    Waveswing America gives thanks

    Posted on Wed 23 Nov 2016 by Waveswing America

    As we reflect on our recent 3rd ranking in the wave energy competition, we are deeply grateful for all the amazing support from all of our partners and colleagues. A key benefit of working with such an outstanding team was that we were able to improve our ACE metric by more than ten-fold over the course of the 1-year competition. This included: (1) Changing the mooring design, (2) optimizing the device structure changing the design from steel to fiber reinforced plastics, and (3) Implementation of three different control strategies in the computational domain that showed a performance upside potential of 2x over the current status. Without our teams relentless efforts, none of these improvements would have been possible:

    1. Mirko Previsic – who led the team to success bringing his deep insights in techno-economic optimization of WEC devices to the table, including the structural design and controls optimization.

    2. Simon & Jude from AWS energy – our primary Scottish partners. They brought in the technology and a deep background and design-intuition on this device having been involved with it’s development for a long time.

    3. Johannes Spinneken who played a critical role during the tank testing campaign.

    4. Anantha Karthikeyan – a member of the team at Re Vision Consulting, who worked on the controls optimization and numerical simulation work leading to a potential performance improvement of 2-3X.

    5. Ajay Mathew – a summer intern who helped us during the tank testing campaign with post-processing of data.

    6. Jeff Scruggs at University of Michigan who developed an optimal feed-back controller for the machine based on the theory he developed.

    7. The COWI group in the San Francisco Bay area. They were instrumental in the structural re-design effort, going from steel to FRP.

    8. 4c Engineering for designing and building the two scale models that were required for the competition.

    9. Oregon Ironworks a steel mfg based in Oregon for the help in assessing steel structural costs.

    10. Orenco Composites a FRP manufacturing outfit based in Oregon who helped us refine our design and manufacturing process.

    11. University of Iowa for letting us test our 1:50 scale and 1:20 scale device there.

    12. We also would like to acknowledge the tremendous effort by the WEC-Prize team, which includes the National lab team and the amazing crew at Carderock.

    Finally, a really warm thank you to the US Department of Energy – in particular Alison Labonte and Jose Zayas for their vision in creating such a transformative effort.

    Waveswing America delighted to have secured a prize

    Posted on Wed 23 Nov 2016 by Waveswing America

    Team Waveswing America are delighted to have secured a prize within the competition and with the validation that this provides to the Waveswing technology. This achievement is all the more worthwhile as the Waveswing design is the result of years of development and real engineering and this is reflected in a conservative cost base which constrained our final score. The remaining technical risk is low and further testing following the prize program has delivered full validation of our numerical simulations and the possibility of a 40% uplift in performance through improved geometry. With this uplift and improved structural design which fully leverages the advantages of FRP composites, we believe that an ACE of up to 20 is a realistic possibility, even at prototype stage.

    As the competition closes out, Team Waveswing would like to congratulate all of the competitors for their performance in what was undoubtedly an arduous and challenging competition. We would like to thank the prize team and judges for their fantastic efforts in running an exciting competition and to thank the DoE and US Navy for initiating, funding and supporting the competition. Well done! Finally it just remains to say good luck to all of the teams in the real competition – who will be first to market!

  • AquaHarmonics

    AquaHarmonics sends big ‘thank you’ to all supporters

    Posted on Tue 22 Nov 2016 by AquaHarmonics

    When it comes to brainstorming, our motto is the more the merrier. We are extremely grateful to all of the talented and brilliant people who let us bounce ideas off of them,and who shared their expertise with us. A big thanks to Chris Patton for his ideas, support, and checking of our Numerical Analysis, Saghy Saidtherani for her revised Numerical Analysis, the one and not only Bill Murray for his cursory review of our device, Young Sang-Song, Justin Guevara and Linda Brown for reviewing our technical submittals.

    We’ve said it many times before, but we wouldn’t have achieved what we did without the structure and focus that the wave energy prize provided us. In addition to providing rational metrics and checkpoints for our development, we were also introduced to extremely helpful, encouraging, and inspirational people along the way. We want to thank the DOE, and Alison LaBonte for putting this all together, Julie Zona for being an amazing administrator, the Carderock Team, The WEP team, the developers of WEC-SIM, the team at the University of Michigan Marine Hydrodynamics Lab, and the team at the Oregon State University O.H. Hinsdale wave lab.

    There is no way we could have tackled the technical challenges we did without the motivation, encouragement and support of our friends and family. The wave energy prize required a lot, especially for two guys working full time jobs with all the associated stress and time commitments. There were times when we questioned why we were giving up so much of our free time, late nights, early mornings, time off of work (that could have been used for vacations!), and even our own funds. It was all the people that believed in us that gave us the extra boost we needed to keep going:Joe Monson for his extreme patience and proficiency as a manager as well as supporting crazy ideas, Hillary Shoop for her enthusiasm, networking skills, and for believing in us, Will Vanlue for making our Logo and for him and his wife Leah being such awesome neighbors when we’re tinkering in the garage at 2 AM, Justin Dedini of Rucksack Roasting for providing us the best, custom coffee, Reuben Brown for helping out with a whole variety of strange tasks, Gabrielle Brown for her support in getting the word out and for finally not referring to Alex as “dumb dumb head” anymore, Elizabeth Collins, Kim Collins, and Ariel McLane for getting the word out and rocking social media for us , Niki Lendo for her enthusiastic support as well as being an excellent tour guide while in Michigan for testing, Jaime Miller for her support and inspiration, Ezekiel Brown for being our stand in CEO as well as providing alternative viewpoints, James Honkola for being Ezekiel’s stand in replacement for bouncing ideas off of, Chris Mesker for his support, sense of humor and enthusiasm, Ivan Lehecka, David Pasc, Nick Cornilsen, for their support, Nick Erwin for his enthusiasm and suggestion of changing our name to “two dudes in a garage”, Devon Bullock for his extreme optimism, Erika Dedini for her good luck charm and optimism, our day job employers, Precision Castparts and Cylance for allowing us the time and means to work on this project, Patrick Hinkle for his support and inspiration Bobby Bochsler, Mathers Heuck, for believing in us, Steve Quinn, who wished only to be referred to as Q, thank you for believing in the crazy ideas as well as dumpster diving for Styrofoam for our first prototype, Linda Brown for her inspiration and support, Neil Slotvig for inspiration, Chris Hager for his culinary skills, cheesecake and- yes maybe I do want to go in with you on a sailboat , Michael and Nellie Hand, Jacob hand ,The Hand father for listening to our crazy idea and when we had patent questions, our parents, Laurie Levites and Harvey Ginsburg, Elke and Wolfgang Hagmuller, our siblings Seagen Levites, Celia Levites, Meira Pomegranate, Sonya Hagmuller, a big thank you to Rebecca for her support and keeping us nourished through the countless late nights, early mornings, and weekends when Max and I were at our wits end, love you tons!

    Thank you to everyone who has chronicled our efforts, especially Pete Danko for visiting us in our “laboratory” and his fantastic articles, and Cinthia Gibbens-Stimson and the Cordova Times for following our efforts and getting the word out in Cordova, Alaska.

    And again, a really big thank you to all of you who have followed us here and on Facebook, it means a lot to us to have this many people interested in what we are doing, and that we can inspire others to dream big!

    We would also like to congratulate all the teams that participated in the Wave Energy Prize and all their technical achievements made along the way. If all goes well, we will be seeing some of these devices in the water in the near future! Best of luck to everyone and their development, and please stay in touch!

    WAVE ON!

  • Harvest Wave Energy

    Harvest Wave Energy attends Frontiers Conference

    Posted on Thu 13 Oct 2016 by Harvest Wave Energy

    This article has been reproduced from the original post on Harvest Wave Energy’s Blog.

    Taking an unproven technology from the laboratory to commercialization is no small task. In order to survive you need to be agile, opportunistic and have plenty of help from your supporters. Our participation in the Department of Energy’s Wave Energy Prize competition has provided a number of monetary and non-monetary benefits that have been critical to our survival so far and for which we are eternally grateful. Foremost was the $125,000 in seed funding the DOE provided to each of the nine finalists in order to fund fabrication and testing of 1:20th scale wave energy prototypes. Of equal value to our technology’s development has been the wave tank testing and engineering support that the DOE has made available to participants of the competition. And we shouldn’t forget the contributions from our corporate partners, MathWorks, Autodesk and Resolved Analytics, who have provided reduced fee software and services as part of their missions to promote entrepreneurship and innovation.

    But perhaps the coolest perk of all is the opportunity offered to us last week to exhibit our wave energy technology at the upcoming White House Frontiers Conference. I encourage you to read more about the conference sponsored by President Obama here as it promises to be a very unique opportunity to see first hand a large number of exciting and innovative technologies attempting to solve the world’s greatest challenges. We share the administration’s belief in the potential of wave energy to provide clean, renewable electricity to communities and cities across the United States. We are thrilled to have this opportunity to share our work with other entrepreneurs and technology developers facing similar challenges and look forward to learning from them as well.

    We will be blogging, tweeting and possibly Periscoping from the conference and hope you tune in. Follow us on LinkedIn and Twitter for the latest updates. And if you will be at the conference please come by our exhibit to learn more. Officials from the DOE’s Wind and Water power program will be there to answer questions about the DOE’s mission and vision as well.

    AquaHarmonics takes break from testing and attends ocean energy conference

    Posted on Mon 26 Sep 2016 by AquaHarmonics

    Team AquaHarmonics has been enjoying a little break after testing was completed at Carderock.

    Last week we attended the Ocean Renewable Energy Conference here in Portland, Oregon. We met a lot of interesting people that have been working within the industry and listened to different panel’s of speakers regarding the many things that will have to happen for wave energy to take off here in the U.S.

    Overall, a great experience and we hope to be there next year. We wish the remaining teams good luck in their testing and will see everyone on November 16th at Carderock!

    Team SEWEC prepares to test at Carderock

    Posted on Fri 23 Sep 2016 by SEWEC

    Did we draw the long straw or the short straw when we heard in July that we would be the last team to test our device in the MASK basin at Carderock? We’ll certainly be older we thought, possibly wiser, maybe even better informed. What we didn’t realize was how much more relaxed we’d be as the rush to complete our device, test it, load it into the container, finish the team test plan etc. etc. by the July deadline has all faded into the past.

    After a well- earned summer break, we’ll swing back into action next week, open up the container, open up the crate and prep SEWEC for tank testing in the week of October 6th. As a warm-up we have been reviewing the vacuum pump we will be using to pull most of the air out of Sewec – enough to get the same “air elasticity” expected with the much higher pressure swings that will be generated in a full scale unit. We lucked out again in finding another great supplier/partner to help us in the competition – Associated Vacuum Services of Santa Anna, California Bob Tumbrello, GM at Associated Vacuum had our pump pre-tested and promptly uploaded a video so we can see what are getting

    Not only that, Bob encouraged us mightily by associating us with previous technology pioneers he has supported – his company has just built a satellite chamber for SPACE X and a few years ago they did the testing for the Alpha Magnetic Spectrometer project which was on the Endeavour shuttle’s last payload up to the International Space Station.

    Says Bob - “We’re a small group of people doing very big things sometimes - it’s a lot of fun!”

    Looking back on our hectic build phase we worked with a whole slew of professionals who enthusiastically helped us with our special needs. We have been very lucky – they all hit it out of the park.

    Back to the checklist for Carderock. Nick, Tom, Byron, Carol, Sean – we’re back on stage! Now where did we stash the keys to our PackRat container?

    CalWave completed testing and reviewing next steps

    Posted on Fri 23 Sep 2016 by CalWave Power Technologies

    After a week of thorough preparation, CalWave Power Technologies completed a successfully week of 1/20th model testing at the MASK basin. Our team was impressed with the Carderock facility and the knowledge and experience of the staff and Prize committee, we had the privilege of working with. It was exciting to observe our prototype in the various Prize specified wave conditions, especially the realistic wave cases and want to thank the facility for the high quality photo and video documentation during this hectic week of testing.

    We are currently in the process of reviewing preliminary data from testing as we plan our next steps with industry partners and are excited to analyze the complete data set when it becomes available. At the same time, we started to reflect on everything we were able to accomplish and all of the hard work from numerous individuals that made it possible in the given time frame of the prize. As we await the final results of the Prize, we would like to wish all other teams the best of luck!

    RTI busy setting up at Carderock

    Posted on Thu 22 Sep 2016 by RTI Wave Power

    Our August update may be a bit shorter than our prior updates because we are now here at Carderock during Set-up Week implementing our Test Plan with a talented and helpful Carderock crew. We hope to complete our load cell and encoder spot checks tomorrow and then Sean and I (the RTI mechanical team) will be joined by part of our electronics team (Dr. Nathan Weise and Diane Liskey) for the remainder of Set-up Week and all of Test Week. Dr. Weise, who teaches EE at Marquette U. and has built a powerful programmable digital Power Take Off system for our RTI F2 QD 1/20 scale model, has focused on the application of power electronics to Wave Energy for several years. He worked with RTI on the predecessor RTI F1 prototype while previously at the U. of Maine.

    We remain confident that the global wave energy industry will converge on one or more WEC concepts which can utilize this huge global renewable resource (which is several times more concentrated than solar or wind) and produce renewable power at a lower cost than solar or wind. Once major international power equipment companies recognize that a new generation of wave energy converters (WECs) can
    compete with wind power and they can apply their recent marine experience with the rapidly expanding off-shore wind market, they will make the commitments necessary to propel the WEC industry forward.

    RTI believes that WEC technology convergence will lead to deep water, surface deployed, terminator type WECs which intercept and capture maximum heave and surge wave energy per cubic meter of WEC marine vessel employed (for lowest CAPEX). We also believe that the most secure way to protect surface WECs during severe sea states is to flood and submerge their float(s), an internationally patented feature of the RTI F2 QD and other RTI WECs.

We were pleased to complete the required competition waves by mid-week, leaving time for a number of additional tests using different configurations. The model’s power output was well matched to our numerical models and earlier testing.

    It was a privilege to have access to one of the best wave basins in the world, and the data and experience acquired will be invaluable on

  • Harvest Wave Energy

    Harvest Wave Energy gives thanks for support

    Posted on Fri 19 Aug 2016 by Harvest Wave Energy

    This article was originally published on the Harvest Wave Energy Blog.

    Over the past year our team has been hard at work on our entry into the US Department of Energy’s Wave Energy Prize competition. The prize was intended to be challenging and to push us to the limits of our capabilities. Our team, along with 8 others, has passed through a series of stage gate reviews including an original technical design package which has followed us through the competition and continues to evolve, a series of numerical model simulations and 1:50th scale modeling verification of those results, and recent preparation for 1:20th scale model testing to be completed at the Naval Surface Warfare Center’s MASK wave basin.

    Teams have worked closely with the DOE’s Wind and Water Power Technologies office and their subcontractors. This collaborative work has provided guidance to teams regarding concept feasibility, numerical modeling procedures, performance verification procedures, scale model best practices, and scale model test coordination. I would guess that between the bi-weekly conference calls, group presentations, and other communications we’ve had over 200 hours of direct collaboration thus far.

    Sounds time consuming, right? The long hours aren’t so much of a bear if you can step back and see a big, shiny pot-of-gold at the end of tunnel. For us, that pot-of-gold is the $2.25M in prize money and the opportunity to get in on the ground floor of a nascent industry with immense potential. That’s a pretty cool motivator.

    But, my last week spent with the folks at the NSWC’s Carderock naval facility has me thinking about the hard work of those behind the scenes that have made the Wave Energy Prize a reality. Though optimizing a novel wave energy device in order to have a valid entry into the competition was a lot of work, planning, funding and launching a competition intended to provide breakthroughs in wave energy must have required 10X that effort. And while our initial technical design package pushed us to the limit, the review and judging of those document was also no easy task. And there were 63 teams which submitted packages! And though performing numerical model simulations and taking part in 1:50th scale modeling was challenging, exponentially more so was the development of a set of computation tools that enabled teams to do just that, and the preparation and coordination of 5 wave tank facilities across the nation that hosted teams in Stage 2 of the competition. And for all the work coordinating the 1:20th scale modeling, we should keep in mind that the WEPrize team has done all the same amount of collaboration with each of the other 8 teams. You are starting to get the picture I’m sure.

    Most impressively, these folks are doing so without the pot-of-gold at the end of tunnel. Largely behind the scenes, they aren’t hoping for wealth or fame as a result of their support of this competition and industry in general. They are, instead, motivated by professional devotion. Maybe they have a passion for what they do. Or maybe it is a personal commitment to their country or the social cause of renewable energy. Whatever it is, I’m all for it and have to take my hat off. If any of the developers participating in this challenge are able to achieve their aspirations it is only because of the hard work of the many selfless, talented individuals who have contributed behind the scenes. So, I just want to call attention to the work of a few here.

    Among many others; Jesse Roberts, Diana Bull, Kelly Ruehl, Vince Neary, Carlos Michelin, et al.. Their motto is accurate: “Enabling a successful water power industry”. They have produced a prolific number of publications in both technical and commercial topics related to wave energy over the past 5 years.
    Michael Lawson, Yi-Hsiang Yu, Nathan Tom, Jochem Weber, Al Levecchi, Daniel Laird, et al.. Same as the folks from Sandia; a tremendous amount of background work in market analysis, risk mitigation, research and development, and modeling tools. Most notably, the work performed in collaboration with Sandia on the WEC-SIM suite of computational modeling tools.

    Jose Zayas, Allison LaBonte, Darshawn Karwat, et al.. The champions of the water power industry in the US. They are responsible for implementation of the DOE’s commitment to developing and deploying a portfolio of innovative technologies for clean, domestic power generation from resources such as hydropower, waves, and tides.

    Wes Scharmen, Julie Zona, Phil Michael, et al.. The prime contractor to the DOE. Ricardo folks continue to do a spectacular job administering, guiding and judging the competition.

    David Newborn, Miguel Quintero, et al.. Right now this team is in the middle of eight straight weeks of twelve hour days in which they are certifying team’s 1:20th scale models and managing the wave tank testing of those models. They have done a top notch job making sure that all of the teams are prepared for final testing and have reliable methods of measuring power absorbed.

    This month M3 was proud to be the first team into (and OUT OF) the water at Carderock!

    It was a hot, humid two weeks at the Naval Surface Warfare Center but the experience was amazing. The folks with Wave Prize, Carderock, the DAs, and many more put in long, grueling hours. Hats off to these professionals who will be doing this over and over again over the next 10 weeks!

    Unfortunately, we were not allowed to take photos or video of ANY KIND on the premises. So instead, for this month’s update, we hired expert sketch artists like they use in the Supreme Court. These individuals were able to capture the essence of the moment:

  • RTI Wave Power

    RTI packed and ready to test

    Posted on Thu 18 Aug 2016 by RTI Wave Power

    Team activities have quieted down since we shipped our Pack-Rat on July 18 (photo of RTI principals John Rohrer and Sean Lewis with loaded container), and then finalized our Carderock Test Plan and Technical Submissions at month’s end. Rooms are booked for team members (Dr, Nathan Weise, Diane Liskey, and Michael Macnicoll) who will be joining Sean Lewis and me for Carderock testing. The team is enjoying some well-earned summer vacation which is especially enjoyable here along the southern Maine coast. Because of the time lapse between our pre-testing at the U. of Maine W2 facility and our team’s late September Carderock test date, we are preparing an F2 QD assembly and operating guide.

    This will also be useful for future planned wave tank and open water tests of our 1/20 scale RTI F2 “QD”. The compressed Wave Energy Prize 1/20 scale schedule did not provide the opportunity to fully utilize our numerical model and maximize our wave energy capture efficiency with tank testing (and reduce F2
    CAPEX) using the many adjustable features built into our 1/20 F2 QD model (including drive arm length and orientation, float mass, drag plate depth and surface area, frame submerged depth and seawater ballasting) under multiple random sea conditions. Utilization of composite float or frame components or a reinforced concrete drag plate may lower CAPEX even further.

    One of the most powerful but as yet underutilized features of our RTI F2 QD 1/20 model is the programmable torque controlled motor-generator PTO system developed by our RTI Wave Power Team Marquette University power electronics members (Dr. Nathan Weise, Ramin Katebi, and Drew Maatman). This system allows us to find and program the optimum resistive force applied by our F2 QD float against each wave as it progresses through each individual wave cycle (allowing for example various latching strategies in wave troughs and declutching on wave crests). In future testing it will also allow wave-to-wave adaptive PTO torque control based on the sensed period and amplitude of each oncoming wave.

    Sea Potential tests at U of Maine facility and ships device to Carderock

    Posted on Thu 21 Jul 2016 by Sea Potential

    We were setup and ready for some wet-testing in University of Maine’s new W2 Wind-Wave Basin when we got confirmation that we were going to Carderock. It has been a great effort to date from all involved with the Sea Potential team and we’ll be doing everything we can to bring the prize back to the “Ocean State”.

    We had heard about the impressive facilities in UMaine’s Orono campus from the teams that did their 50th scale tests at the W2 Wind-Wave Basin and were looking forward to getting the DUO launched into action.

    Many thanks to all the team in Maine for their technical support and generous hospitality.

    Roll on Carderock!

    Oscilla Power has just returned from a productive week of tank testing at University of Maine’s W2 basin. Testing of the 1:20 scale Triton WEC went smoothly and power results showed good agreement with our numerical model predictions. Design improvements implemented between the 1:50 and 1:20 rounds of the competition proved fruitful in significantly boosting WEC’s wideband power capture. With a big thank you to the staff at the University of Maine, the 1:20 Triton model is now en route to the MASK basin, and we look forward to official testing in September.

    In June we did a “wet run” in the wave tank at Hinsdale at Oregon State University.

    We tested punt deployment:

    Rigging to mooring system:

    Remote descent to operational depth:

    Mooring dynamics:

    And line tending/device management under crane:

    We also ran waves and collected power data.

    Finally, for fun, we ran bigger waves at a shallower-than-normal operating depth just to stress test the system:

    After a successful week in the tank, we packed up:

    And company surveillance cameras caught the departure of Wave Prize from M3’s facility:

    Team AquaHarmonics is nearly across the finish line! Since our testing at Oregon State University, we have made some updates to the device and controls software and built a mobile work bench that will serve as our base of operations during testing at Carderock.

    We were able to get some volunteer help from my brother in law with the work bench and packing to help get everything complete prior to shipping-thanks Reuben! Our container is packed with our device, spares, tools and our mobile workbench/control center awaiting to be picked up.

    We are very excited to start testing at Carderock, and are also looking forward to a small break before final testing!

    Many thanks to everyone who has worked with us on this project.

    Good luck to all the competitors!


    SEWEC prepares for testing in October

    Posted on Fri 15 Jul 2016 by SEWEC

    The last month has seen a flurry of activity. On June 19th we finished the 1/20th scale model and loaded it into the crate (Photo Patrick with crate) in California. Over the next 3 days it was driven non-stop across the USA to Maine whereupon Nick G, Nick W and Sean prepped it for operation (see photo Sean and Nick with wires) in the new wave tank at the University of Maine Advanced Structures and Composites Center in Orono. Sewec 1/20 was splashed on June 28th and floated to her marks! We then spent five days putting her through her paces - and everything worked - thanks to Byron and Nick G. We even ran the configuration to skip every second wave - reported as a simulation curiosity in an earlier team update - see the video so bravo to Sewec’s numerical modelling crew. And a big thank you to Anthony Viselli, Matt Fowler and Matt Cameron who got us up and running and got a ton of data for us at U of M.

    Then back into the crate (see photo Tom with crate 2) minus PTO valve and orifice plates which we finally calibrated the following week at San Jose State University, in an upgraded rig. Back on the plane to Bangor the following Monday with the valve and orifices, get Sewec out of the crate and run a vacuum test at the U of M. The Advanced Structures and Composites Center routinely vacuum bag their composites and they kindly deployed their equipment and considerable expertise to evacuate and catch every last air leak on Sewec. The photo (Chris with vacuum) shows Chris Urquhart, vacuum maestro at U of M listening for leaks and photo (0.28 psia) shows the steady state value we ultimately reached of 0.28 psia. We need 1/20th of an atmosphere absolute (0.75 psia) in the Carderock test to account for scaling of the OWC air volume, so we should be ok. As far as we know, this will be the first time this technique has been used to increase scale model air elasticity so we really wanted to be sure we could pump 95% of the air out of Sewec, without leaks or structural collapse. Our fabricator Tom Johansing ran a stress analysis in May and said then “You’re good”. Thanks to Tom we are good to go.

    Our team is the last to test at Carderock and this thought cheered me a lot as I loaded Sewec back in the crate Friday evening. Team Sewec “has a wrap” and is looking forward to an extended summer break.

    RTI completes shakedown testing and is ready for Carderock

    Posted on Fri 15 Jul 2016 by RTI Wave Power

    June was the first month in the water for our RTI F2 QD. Our “first splash” and “first waves” were in the UNH Chase Labs deep tank and wave tank, respectively (RTI Teammates Toby Dewhurst and Sean Lewis in lower left, setting up for “first waves”). All key components arrived in time for a final assembly by mid-June. A special thanks to team sponsors Sensata-BEI (providing marine grade high resolution encoders), Interface (submersible Load Cells) and UNH Chase Labs (wave tank access).

    A successful series of shakedown and preliminary performance tests were conducted in late June at the U. of Maine, Alfond W2 Wind-Wave Facility in Orono Maine (photo lower right). This new world class wave tank facility with its 5 meter depth and Edinburgh Engineering wave makers allowed us to more closely simulate the ONR Carderock Mask basin Wave Energy Prize test conditions. Apparently many of the 9 Finalists also discovered this facility with others testing before and after us. This was the first time our electrical and control system (developed by our Marquette U. E&C group of Drew Maatman and Ramin Katebi under Dr. Nathan Weise plus Diane Liskey) was merged with our RTI F2 QD hydrodynamic and mechanical hardware numerically modeled, designed and fabricated by our Maine/New Hampshire group of Sean Lewis, Toby Dewhurst, Dick Akers, Mike Macnicoll and yours truly, John Rohrer).

    Convergence on the most cost effective ocean survivable Wave Energy Converter (WEC) configuration (a major objective of the Wave Energy Prize) is essential before the nascent WEC industry can effectively tap the huge global wave energy resource which has several times more energy density than the solar and wind energy which produces ocean waves. We continue to believe this WEC convergence is pointing towards surface deployed elongated wave terminator type WECs intercepting maximum wave front using minimum vessel volume (and cost). The patented RTI F2 QD is the only such WEC which floods and totally submerges its elongated surface float safely below the troughs of even 15 meter high waves for secure survival in seas which would destroy other surface WECs.

    Oscilla Power is in the final stages of constructing the 1:20 scale model of its Triton™ WEC. We are currently integrating PTO and instrumentation onto the fiberglass surface float hull, which arrived from Janicki Industries a couple of weeks ago. The foam mold for the heave plate arrived from Janicki today and we will be casting the concrete heave plate structure in it later this week. A trial cast of a heave plate ring section yielded successful results.

    Following the build and final instrumentation checks, the model will be shipped to the University of Maine, where we will perform pre-testing at the W2 wave basin in early July.

    The Waveswing America team has been working hard to finish the build and testing of the 1:20 scale Waveswing with excellent results. Our direct-drive PTO unit is working better than expected with excellent force and velocity control response which allows us to implement the most advanced control strategies available. Combined with the low absorber mass giving excellent response and the low structural volume, we really feel that the Waveswing is the Ferrari of wave power!

    We have now assembled the complete system at the University of Iowa wave tank and commence testing in earnest tomorrow. This will allow us to tune the control system and iron out any problems with the device before finally packing up for shipping to Carderock. It is really pleasing to see the efforts of so many different people all coming together to
    produce such a great result.

    Go Waveswing America!

    SEWEC assembles final 1/20 scale device

    Posted on Mon 20 Jun 2016 by SEWEC

    The past month has been even more hectic with final assembly of our 1/20th scale model - many components had to be “adjusted” to fit at the same time as we were completing our input for Technical Gate 3. Byron Barnes has worked into wee hours many nights.

    Photo 1 shows the bare device core on the left with the bow Styrofoam cutout in the background.

    In photo 2 you can see the assembly being fiberglassed - inverted on our custom build frame/test cart.

    Photo 3 shows SEWEC sitting snugly in the crate (thanks Patrick) before shipment to the University of Maine for pretesting in the last week of June.

    Also in June our calibration team at San Jose State University swung into high gear, measuring and calibrating SEWEC’s PTO system. Professor Liat Rosenfeld’s team - Tamir Alquran and Brian Hulliger followed Nick Gray’s test protocols to measure and document the position/flow/pressure drop data that will be used to measure power absorption in wave tank testing. Photo 4 shows the SEWEC valve and orifice plates being calibrated in the SJSU lab.

    On June 28th we splash and then start to tune and pre-test SEWEC 1/20 in Orono, Maine. Thanks to all hardworking team members and contributors who got us here on time. Our next update will show SEWEC 1/20 in her element, sucking power out of the waves. Stay tuned…

    RTI preparing for shakedown test at University of Maine

    Posted on Sun 19 Jun 2016 by RTI Wave Power

    The pace of activity to complete and pre-test our 1/20 scale model has continued to accelerate this month as we recently completed our Carderock Test Plan and other TG3 submissions and are now preparing our 1/20 scale RTI F2 QD prototype Which Sean Lewis and I will take to the new world class U. of Maine, Orono W2 (wind & wave) Facility for several days of shakedown tests.

    Dr. Nathan Weise (formerly with U. of Maine and now with Marquette) has been busy preparing our NI Lab View based programmable motor-generator control system with assistance from 2 of his Power Electronics students, Andrew Maatman and Kamin Katebi. They have been working with duplicate sensors and a duplicate motor-generator but will connect to our 1/20 scale prototype for the U. of Maine tank pre-testing next week joining our east coast EE Diane Liskey there.

    Our prototype is essentially complete but we wish we had more time to pre-test and optimize its performance. Our hydrodynamics and modeling team (Richard Akers, Toby Dewhurst, and Michael Macnicoll) have provided simulation modeling insights as to what model settings should yield the best results (using PTO resistive force, float and frame weight distribution, drag plate depth, and other adjustable parameters on our 1/20 model).

    We remain excited about the inherent high capture efficiency and low capital cost advantages of our patented RTI F2 QD wave energy converter (WEC) technology combined with our submergible Float for maximum severe sea security. We remain convinced that a successful WEC (which can beat solar and wind farm economics) must intercept more wave front (per unit of WEC vessel weight and cost) to capture more wave energy. This requires a self-orienting WEC with an elongated wave front parallel float deployed on the ocean surface in deep water (where wave energy is greatest) capturing a majority of both heave and surge wave energy.

    A big week for team SeaPotential and the 1/20 scale DUO

    Posted on Sat 18 Jun 2016 by Sea Potential

    This week the ring and float structures arrived in our temporary work space in the HawkWorks at Roger Williams University, delivered by a team of first-rate metal fabricators at Bristol Rhode Island based Luther’s welding.

    After some initial testing, to make sure all the pieces fit (supervised by Team Leader, Tim MacDonald’s pug, Paco), and some wiring of our control panel by local electrician Bud Souza, Chief Technologist Paul Brewster is comforted we know have a complete kit.

    So, we loaded up our kit, and headed up to Maine to do some tinkering in the test tank at the University of Maine, in Orono.

  • As it was for all the teams, this past month has been a busy one for Mocean. Getting our 20th scale model ready for the TG3 deadline was a lot of work. We had to make some last minute adjustments to the model, work with three machinists, and get some overtime help from our machinists and controller maker to get things done for Wednesday.

    As alternates, we are in a more precarious position than the finalists. And it may be that despite our best efforts, this technical submission was our final one. We hope this is not the case, and we are ready test our model in Carderock. But if is was, it’s been a fantastic experience, and we wish the all finalists the best of luck (especially M3)!

  • The Wave Energy Conversion Corporation of America (WECCA) has been busy completing all the necessary tasks associated with completed the 1:20th Scale Model.

    Harvest Wave Energy tests 1/20 scale device at the University of Iowa to prepare for finals

    Posted on Thu 16 Jun 2016 by Harvest Wave Energy

    Recently, in final preparation for our participation in Wave Energy Prize final round model testing, we have performed a series of 1:20th scale model tests at the University of Iowa in order to make final adjustments to our Wave Energy Prize entry. We have posted a video of the deployment of our device on our blog you can find here:

    University of Iowa Testing Facility
    University of Iowa Testing Facility

    Additionally we were asked to answer a few questions about our participation in the Wave Energy Prize; below are our responses:

    Why are you participating in the Prize?

    Our team is primarily motivated by the immense challenges of both engineering the world’s first cost-effective WEC system and commercialization of the technology. We are also motivated by what we see as the immense market opportunity that wave energy will address due to the shortcomings of existing renewable energy technologies related to the intermittent nature of solar and wind energies. We have recently published a video exploring the impact of solar intermittency on future renewable energy marketplace dynamics in California which you can find here:

    What do you think the role of government in driving innovation is?

    The term “driving” may be over-reaching as private enterprise is always going to have greater motivation to drive innovation than public policy makers due to risk profiles. But it’s well established that government has a key role to play in defining technical and commercial challenges that align with societal needs and for financially and technically supporting early-stage technology developers that are pursuing the most innovative concepts. This is the SBIR model and it’s benefits have been proven many times over.

    What has been the biggest challenge so far?

    Convincing ourselves that the technical and commercial challenges are not insurmountable has been key to maintaining the focus and effort level necessary to compete in the Wave Energy Prize. Technically, one of our biggest difficulties is that computational models are inadequate for assessing some of the more complex dynamics of WEC systems and so wave tank testing, with its high costs and effort required, is in some cases the only available method for discovery and validation.

    What is unique about your device?

    It is the first attempt at a deep-water, oscillating wave surge collector type device intended for grid-scale electricity production.

    What changes have you made in your device and approach over the course of the Prize?

    We’ve made so many significant changes that I’ve lost track. Those I can recall include limiting the number of degrees of freedom to improve reliability, transitioning from a fixed frame to a taut-moored design to reduce costs, and to sharing power conversion equipment between multiple energy collectors.

    What have you learned about WECs since participating in the Prize?

    Most importantly we have learned that the oscillating wave surge class of devices has the highest potential for techno-economic performance of all WEC classes.

    What are your plans if you win the Prize?

    Whether or not we win the Wave Energy Prize our plans for the future include a year long R&D process to further develop our conceptual designs to improve techno-economic performance prior to our first ocean-going pilot scale demonstration scheduled for 2018.

Thank you to the Wave Energy Prize and Carderock teams for arranging a tour of the very impressive MASK basin. We were able to assess the test area and laboratory space to ensure that our testing in September goes smoothly.

    Having worked with Einhorn Engineering on the detailed design of our 1:20 scale model, we have started construction on key elements and placed orders for long lead items. The model’s surface float hull is being manufactured by Janicki Industries, a leader in composite manufacturing. We are finalizing the geometry of the model’s heave plate and expect to start construction on it shortly. The damper units that will represent the PTO have arrived and are in the process of being characterized on a custom built test apparatus.

Most of our components are now here - the question is now will they fit together - or has our QA failed us so we have to scramble?

    In parallel to our build we are getting to know SEWEC much better - in particular how to configure her to maximize energy capture from particular sea states. The video shows one strand of our simulation work - and far and away the best for visualizing how crashing right into waves can suck out all their energy. The video shows a eureka moment in team member Paul Mcevoy’s OrcaFlex simulation of SEWEC - we know, numerically, why SEWEC is only hitting on every second wave!

    After deployment and anchoring meetings with OSU Hinsdale (site of June shakedown runs of 1:20 scale device), the team decided the best method to simulate the anchors at Carderock was to hard mount to the 1” threaded holes situated on the tank walls. Thankfully, M3 has experience doing this with our 2011 1:6 scale testing in the same flume. Not only do we still have full CAD of the tank mounts and brackets from that work, but after some bushwhacking on the M3 Wave backlot, we located the original 2011 heavy steel bracketry already pre-drilled to the tank patterns. Score!

    Sea Potential at Team Summit then back to work

    Posted on Fri 13 May 2016 by Sea Potential

    It was great to meet all the teams and Prize administrators at the “Team Summit” in Washington. Phone calls and webinars are good – meeting the people and personalities face to face is much better and it was an excellent idea for the Wave Energy Prize to arrange this.

    The visit to Carderock to see the test facilities was the highlight of the week - it was a bit like walking the pitch before a big championship game!

    Great idea and it is doubtful if any team could deliver a successful test performance without this initial briefing and first-hand experience of the impressive MASK facilities.

    It was then back to action with construction of the 1/20 model – with the support from the engineering and manufacturing talents Rhode Island has in abundance.

    Luther’s are doing a great job constructing the aluminium hulls structures and mechanical components and it’s great to see the parts from the drawings come to life.

    We want to also give a special mention to the team at Roger Williams University who are co-ordinating the component deliveries s and providing the facilities at their Hawkworks Lab for the assembly and component testing over the next few weeks. Tim is pictured at Hawkworks as we inspect the first shipment of parts from Luther’s to begin assembly.

    The next few weeks will be critical to the team’s success in the Prize competition and the challenging timescale of the WEP final is setting everyone’s pulse racing. There will be an enjoyable evening had by all in mid-July when the model has been delivered successfully!!

    RTI Team Leader proud of his “all volunteer army”

    Posted on Fri 13 May 2016 by RTI Wave Power

    April was our Team’s “finalize design and order components” month. May is our “build and assemble” month so we can hit the wave tanks in June. We plan to utilize the UNH Chase Labs tank first for some initial shakedown trials. Its limited depth, however, requires us to finish our RTI F2 QD 1/20 model testing and tuning at the new U. Maine, Orono Wind-Wave (W2) Alfond facility with its 5 meter depth and state of the art Edinburgh digital wave makers. Our local fabrication and welding shops have done a great job with our 1.4 meter wide Float and Drag Plates. Next week they will be working on our twin vertical Spar Frame and our two watertight PTO housings (holding our motor-generator, gear reduction drives and encoders).

    Nathan Weise and our RTI Electronics & Controls group (Diane Liskey, Rick Sparrold, Siavash Pakdelian, and Mahshid Amirabadi) are working with National Instruments Field Engineer, Peter Rifkin to assemble our DAQ and Programmable Control system.

    Our Hydrodynamics & Simulation group (Dick Akers, Toby Dewhurst, and Michael Macnicoll) have our new 1/20 scale RTI F2 QD model up and going and are optimizing Float and Frame weight distributions, water plane areas and lots of other cool CFD stuff which I honestly do not fully understand.

    As Team Leader I am proud of the work and accomplishments of our entire “All Volunteer Army”. The F2 QD is the 10th Generation of WEC RTI has developed and wave tank tested over the past 7 years. Wave Energy has an intrinsic cost advantage over solar and wind because it utilizes a renewable resource with several times higher energy density. We are hopeful that the Wave Energy Prize will provide the convergence needed on the most economically viable WEC concept(s) to make Wave Energy attractive to global global power equipment producers and renewables project developers which will turn wave energy into a major renewables industry.

  • Harvest Wave Energy

    Harvest Wave Energy shares industry perspective

    Posted on Fri 13 May 2016 by Harvest Wave Energy

    The following was originally posted on the Harvest Wave Energy blog.

    In February of 1987 the New York Times published an article on the potential for electricity produced from ocean waves. Fast forward 30 years, and we have a more recent article by ABC musing, “Whatever happened to Wave Power?”. The easy scapegoat would be the unwillingness of public and private capital to take part in high risk endeavors. That position is dubious when you look at the following facts. US DOE funding of wave power research has totaled >$100M from 2008 - 2015. Available data indicates that cumulative European government funding was likely twice that amount during the same period. Other data points indicate that private capital funding of early stage research has easily surpassed public funding levels. So, with such a high level investment, why has the industry failed to progress?

    We believe that private enterprises involved in wave energy have, over and over, made the critical mistake of ignoring market risk. That is, as Eric Ries states in his book “The Lean Startup”, such companies have failed to ask and answer the question of whether or not a product should even be built in the first place. Let us explain.

    When launching new products, innovations or ventures, companies have a tendency to focus all their attention on technology risk. They barrel ahead, asking and resolving the important technological questions concerning “what is my innovation?”, “how can I build it?”, and “what resources will I need?” and then they set forth building it. At the end of the journey they finally get around to asking “How does my new product fill a market need?”. Unfortunately by now, so much time, energy, and resources have been plowed into the technical research and development process that companies experience an escalation of commitment to the new innovation and tend to brush over and sprint through the appropriate market research in order to bring it to market as fast as possible.

    Based on progressive results over the past decade, solar and wind energies are now considered the de facto standards of sustainable power production. Even conventional hydropower is finding it hard to find a seat at the table. Therefore, now more than ever, wave energy device developers need to begin by asking “Who is going to be willing to pay for this technology if I spend the time and effort to develop it?”. Without the answer we may be doomed to repeat the mistakes of those that have come before us. So what’s our answer?

    Stay tuned.

    Posted on Fri 13 May 2016 by AquaHarmonics

    Team AquaHarmonics is proud to present the first complete build of our device! This photo was taken late at night as a tribute to our strange schedules, but the result of our dedicated work is a complete device ready for bench testing on schedule! We have a few remaining final parts to be manufactured and final ballasting to be completed, but the device is nearly tank ready. Next up for us is bench testing of the device with the control system and characterization of the Power Take Off. This puts us on track to do preliminary testing at Oregon State University in early June. Many thanks to everyone who has helped us get here on our highly demanding schedule. Stay tuned for more updates!

    What do you think the role of government in driving innovation is?

    The role of government in driving innovation is critical in the renewable energy sector in progressing these technologies towards viable commercialization in a few ways.

    Particularly challenging to wave energy is the all important payback of the initial investment. Private investors typically seek short payback periods for their investments, and this has placed a huge burden on past wave energy development.

    This has caused early developers to go from a partial scale model to full scale too quickly, and the resulting cost overruns in deployment and maintenance as well as less than anticipated power production has made investors of wave energy a bit leery. Wave energy development needs a more long term plan with more realistic expectations on payback to keep it moving.

    Government funding, implemented in ways such as the Wave Energy Prize allow for a focused and critical view of the available technologies from highly skilled people in the field with these long term outlooks as a final goal. This can quickly reduce the field of available technologies to the most likely ones to succeed while giving developers direction into what matters in the big picture at the utility scale instead of only focusing on how to make power out of a single device.

    The difficult part about wave energy is not how to make power as many devices that have been tried do in fact make power, but rather how to do it in an economic way. The Wave Energy Prize in particular can help fast track this solution by comparing the entire available field of devices in a true “Apples to Apples” comparison.

    If you look at the state of wave energy technology, you have over topping devices, point absorbers, oscillating water column devices, line terminators—-the list goes on. As humans we are very good at optimizing something once we know what to optimize, and with wave energy, we don’t know what that is yet. We all know the best ways to make power from wind energy for instance. It is a blade attached to a generator placed on a tower.

    All of these aspects have been around for awhile and we have put our time into optimizing the height of the tower, it’s location, the design of the blade, the design of the generator, etc. This has resulted in wind energy being a very competitive resource. We know what a car and an airplane should be and we have optimized them. Wave energy simply hasn’t found the device to focus on for optimizing. Once we do, the development will certainly move very quickly to becoming highly competitive.

    What is unique about your device?

    Our device Power Take Off is unique in that it uses relatively simple and well known power technologies to convert wave motion to electrical power in very few steps, with no limit in operational stroke, meaning it can make full use of any given wave height with no “end stop” conditions. The device hull is a simple, robust shape designed to handle the worst weather conditions it may see in operation.This design strategy results in a wave energy converter that is simple, light weight, robust and low in capital cost.

  • Chris had a great time at the Team Summit and NHA/IMREC/METS Conference. It was fantastic to meet the other teams and very exciting to see the Carderock MASK basin. And we are continuing to make good progress with our 20th scale build.

    Waveswing America finalizing design and preparing to build

    Posted on Mon 09 May 2016 by Waveswing America

    The Waveswing America team has been working hard to finalize the design of the 1:20 scale model for testing at Carderock. Whilst the design is very similar to that used for the 1:50 trials earlier this year, we have focused on improving the fidelity of the model, incorporating the active PTO system and engineering for reduced losses. We now have now signed off on the design and parts are being machined.

    In parallel with the mechanical design, we have also been progressing our dynamic control software. Data from the 1:50 trials has allowed us to refine and validate our numerical models which are essential for tuning the control system so that we can achieve maximum output.

    Lead members of our team attended the Wave Energy Prize Finalists Summit in Washington DC in April and enjoyed meeting both the other competitor teams and the DoE and Prize Administration teams. The even proved most useful with the highlight being the visit to the MASK basin at Carderock.

    Over the next few weeks we will begin assembling the model, complete the design and build of the self-deploying anchor system necessary for the large tank, finalize the control systems and make preparations for a return to the University of Iowa for pre-testing of the 1:20 scale model.

    Sea Potential focuses on optimizing the 1:20 scale model

    Posted on Mon 18 Apr 2016 by Sea Potential

    The team’s focus at the moment is on optimizing the 1/20 model for the final.

    The analysis of the data from our 1/50 tests at University of Iowa and numerical modelling using the advanced coupled analysis features of Wood Group Kenny’s Flexcom software have helped identify some small structural improvements that will increase the ACE metric for the 1/20 model.

    The state-of-the-art coupled analysis capabilities of Flexcom are also key to optimizing the mooring design for the MASK basin – this will be important for the HPQ score that will determine prize winners from the teams that can exceed the 3.0 m/$m threshold.

    An animation from the Flexcom modelling is shown below.


    The other software Sea Potential are employing for the optimization work is the new techno-economic software from Exceedence. The unique “Goal Seek” and “Sensitivity” modules have enabled the Sea Potential team to identify where specific improvements can be made for the range incident wave conditions for the 1/20th-scale experiments at NSWC Carderock’s MASK. The Exceedence software will be a valuable asset in transforming the DUO’s performance data from the Wave Energy Prize into a finance model for wave energy farms around the world - a key step in making wave energy commercial.

    We are looking forward to the Team Summit at “Water Power Week” in Washington – with an opportunity to meet the other teams as well as catching up with colleagues from the wave energy sector.

    One of the more interesting opportunities that could emerge from the Wave Energy Prize is for teams to merge and co-operate to bring the promising technologies through to commercial reality – while some technologies will fall short of meeting the necessary performance metrics, the skills and capabilities from the wave energy prize teams can play an important role in achieving the longer term goals that everyone shares for the wave energy sector.

    One of the reasons for participating in and supporting the Prize is that for the first time in this emerging sector there is a clear and transparent bench-marking process that will give confidence to potential investors that the world’s abundant offshore wave energy resources can be harvested in a commercially competitive manner. Convergence around technology that produces independently verified performance metrics that can lead onto commercially viable wave energy technology is a key step to overcoming the fragmented nature of this nascent industry.

    Posted on Mon 18 Apr 2016 by M3 Wave

    The team is looking forward to participating in the WEC Prize Showcase at NHA in a couple weeks and touring Carderock (with a tape measure!). Joining us on the NHA trip will our newest team member, Alice G. Alice is expanding the scope and detail of the numerical models for M3’s technology to provide deeper insights into full scale survivability and reliability. At our Corvallis lab, Mike Delos-Reyes has commissioned the 1:20 PTO test stand and is running initial calibration checks and tuning evaluations. Mike Morrow has completed the first round of PTO and structural designs and will be reviewing them this week with fabricators and machine shops for manufacturability refinements.

    Team member Glosten has wrapped up a series of mooring dynamics models for various operational depths, buoyancy configurations, and ballast ratios. From these curves, we will narrow in on our final system configuration that will be tested at scale prior to shipping to Carderock.

    AquaHarmonics nearing completion of 1:20 scale device design

    Posted on Fri 15 Apr 2016 by AquaHarmonics

    What an exciting time for team AquaHarmonics! We are just about wrapped up with the 1/20th scale device design and have all fabrication drawings completed with many parts and pieces completed or in the process of being fabricated. Our longest lead item appeared to be the hull and we went back and forth a bit on the best way to construct it quickly, precisely and make it robust enough to allow changes.

    Even surprising to us, we landed on a carbon fiber reinforced plastic hull which fits the bill in all those categories as well as allows easy additions of items and repairs if needed. The other exciting thing about CFRP is making a back up device becomes pretty easy and quick once the molds are made. Our first layer of carbon has been laid up, and many of the custom fabricated components are complete and en-route to us. This means that the hull is now waiting on these parts for completion instead of the other way around! We are targeting the last week of April as a first build date, with bench testing to follow.

    Many thanks to everyone who has been providing parts for us and working with our rapid development schedule!

    What has been the biggest challenge so far?

    The biggest challenge for team AquaHarmonics so far has been time. Our focus is primarily the Wave Energy Prize, but the obligations of day to day life, day jobs, etc. tend to come first. This can be quite challenging. We often do the biggest chunks of work between 4AM-7 AM and 8PM-2AM throughout the work week, and then really get some focused hours in over the weekends.

    What are you most looking forward to?

    Team AquaHarmonics is most looking forward to getting the device in the tank and testing with our revised control as this is the biggest “make or break” point for our device. If it works as intended, it can mean a huge improvement in power absorption which translates to a reduction in payback period. This puts us on the path towards commercial success, and furthering development of the device.

  • The team has already started construction of the 1/20th Scale model and is working to finalize the integration of the control system and solidifying the representative PTO system. Working with a constrained budget and time limitations, the team is working to have the model complete and pre-testing completed within the next two months.

    Why are we participating in the Prize?

    Our group is participating in the Wave Energy Prize because this competition is serving as a much needed catalyst for the MHK/WEC industry. Our journey started with a simple and robust idea that has already survived 9 years in the harsh Irish seascape. While that device proved the concept at full scale, the timing wasn’t right. Today with the help of the DOE and initiatives like the Wave Energy Prize, innovative and robust solutions are now receiving the assistance and validation that has been absent historically.

    What do we think the role of government in driving innovation is?

    The government has an important role in encouraging the development of cutting edge capital-intensive development projects such as MHK devices. In the 1970’s, the US Government played a big role in the commercial development of wind turbines for utility scale applications. Since then, the last 45 years has seen an exponential increase in market penetration and confidence with wind generation. The US Government should similarly continue and increase its efforts to develop the MHK industry that arguably has as much if not more potential than the current wind industry. Initiatives like the Wave Energy Prize, grants and government backed loans for MHK developers would significantly decrease risk and increase the rate of development of revolutionary WEC devices.

  • Mocean Energy is progressing with its 20th scale model design, placing orders and making drawings.

    We are also continuing to optimize the shape of our device using a genetic algorithm combined with a custom Rhino3d plug-in.

    Chris is looking forward to meeting some of the other teams at the NHA/IMREC/METS conference in Washington DC at the end of April.

  • CalWave Power Technologies

    CalWave Power Technologies shares video and responds to prize related questions

    Posted on Fri 15 Apr 2016 by CalWave Power Technologies

    Watch the CalWave Power Technologies April update video:

    CalWave responds to questions asked of the competing teams:

    Why are you participating in the Prize?

    Wave power is the third largest renewable resource after wind and solar with the advantage of higher predictability and power density.
    The main goal of the US Wave Energy Prize is double the state of the art economic performance of Wave Power and we want to contribute to that mission in order to secure a sustainable and independent energy supply for the coming generations. Similar to the competition in the US that the Pelton turbine won in 1883 for the most efficient water wheel turbine and that is been in use till today, the US Wave Energy Prize can help to move the entire industry and state of the art forward. It’s the first time in history that multiple wave power technologies are all compared in the same scale and testing conditions by a third party with special focus on economic performance.

    What do you think the role of government in driving innovation is?

    Similar to the duty of our generation of engineers to developed new solutions, it is the duty of the government to support this effort. Sustainable and independent energy is a critical infrastructure challenge that is driving the entire countries economy. If we look back who were the critical players to help wind and solar power to mature to its current stage, the governments and their incentives played a critical role in adoption and scaling of these technologies.

    What have you learned about WECs since participating in the Prize?

    The structure of the prize and feedback of the judges was very valuable and we continued to design based on first principles. Our most valuable learning was to be able to design for the entire life cycle of a converter and economics as the main design specification. We learned how strongly design changes effect the entire system life cycle and how interconnected all aspects and parameters are.

    What are your plans if you win the Prize?

    The prize would allow us to continue to further our technology to support DOE’s mission to help wave electricity generation systems achieve a Levelized Cost of Energy (LCOE) target of 15 c/kWh by 2030.

    What words of advice and encouragement do you have for the remaining teams in the Prize?

    We all have the shared larger mission to develop an economically viable solution to secure us a sustainable and independent energy mix in the future allowing high percentage of renewable power generation. In the mist of the competitive nature of the prize and market, we should step back once in a while and remind ourselves about that fact.

  • Waveswing America

    Waveswing focuses on final design

    Posted on Fri 15 Apr 2016 by Waveswing America

    This month we focused on the final design of the 1/20 scale model, resolving interface issues with Carderock and re-working our numerical models. We have also started ordering parts and are planning our wave tank testing campaign . We are looking forward to visiting the Carderock facility during the waterpower week in DC.

    Also, here are some responses to questions asked of the teams:

    Why are you participating in the Prize?

    Response: Commercially viable wave energy conversion has remained an elusive goal, despite decades of research. The WEC prize is providing an avenue to get radical with our design approaches and pursue game-changing approaches and technologies. These step-changes are critically needed if we are going to crack this problem. It’s also simply fun!

    What do you think the role of government in driving innovation is?

    Response: The government’s role is to encourage innovation by providing appropriate funding mechanisms and development targets. To do that, it needs to provide a sensible mix of market push and market pull mechanisms that are fair and equitable for all players involved. Done properly, it will encourage and nurture a culture of innovation and entrepreneurship typically found in silicon valley startups.

    What has been the biggest challenge so far?
    Response: The 1:50 model scale was difficult to build and was probably too small to provide reliable validation data. We also encountered some issues with modeling our device and were lacking model validation data during the development of our computational model to allow us to debug our model.

    What are you most looking forward to?
    Response: Testing at Carderock!

    RTI welcomes new team members

    Posted on Fri 15 Apr 2016 by RTI Wave Power

    Our team hydrodynamics and simulation (H&S) group (Toby Dewhurst, Michael Macnicoll, and Dick Ackers) continue to calibrate, refine and crunch our RTI F2 QD models to provide design inputs for our 1/20 model to our mechanical design and fabrication (M&F) group (Sean Lewis and John Rohrer). The M&F group is finalizing shop drawings and has started working with local fabrication shops on Float, Frame, and Drive components.

    With our 1/20 scale RTI F2 QD we are attempting a more complex and ambitious PTO control system which should pay dividends in even higher wave energy capture efficiencies than those obtained in our 1/50 scale official Wave Energy Prize wave tank testing. Our Electronics and Controls (E&C) group has, therefore, been expanded. Dr. Nathan Weise, Asst. Prof. of ECE at Marquette has joined us (in spite of the fact that my undergraduate Alma Mata, Villanova, dominated Marquette and Big East basketball this year and went on to win their 2nd National Championship title in March). Nathan previously headed up the Power Electronics group at U. of Maine, where he and several students successfullydeveloped the rotary electric generator PTO for our prior generation RTI F1 WEC. Also joining our team is Dr. Siavash Pakdelian, Asst. Prof. of ECE at U. Mass, Lowell. While previously at Texas A&M he worked on MHK PTOs including those using magnetic gearing. Welcome back to wave energy and thank you for assisting us in selecting our 1/20 scale generators. Our third E&C group addition is Dr. Mahshid Amirabadi, Asst. Prof. of ECE at Northeastern, where she is part of a strong power electronics department. Diane Liskey and Rick Sparold welcome the new E&C group help.

    Waveswing America prepares for pre-testing in June

    Posted on Wed 23 Mar 2016 by Waveswing America

    The Waveswing America team has been working hard on the initial phases of the design of the 1:20 scale model and the associated control system. As our device uses advanced reactive controls, specification of the PTO and the controls system hardware is critical. Because our device is relatively small at full-scale, design at model scale is challenging, particularly due to the scaling effects with regards to mass. We have however found off-the-shelf components which will meet the required specifications and we are now integrating these into the model design. In parallel with this we are further validating the computational models of the device and advancing the controls strategies to maximize production. This work is being complemented by parallel work on hydrodynamics and computational modelling of the device that we are carrying out for Wave Energy Scotland.

    The team recognizes the importance of pre-testing ahead of the prize runs at Carderock and so we are busy planning for this activity during June. All of this puts a degree of pressure on schedules however we are confident that we will meet the necessary deadlines.

    Finally we are looking forward to the Finalists Summit in DC in April and are working on an in-water desk-top display of the 1:50 scale model for the exhibition. See you all there!

    RTI Wave Power celebrates and then gets back to work

    Posted on Mon 21 Mar 2016 by RTI Wave Power

    A brief team celebration followed the March 1 Wave Energy Prize announcement of Finalists. Soon thereafter, however, reality set in with lots of work before us between now and July 18 to do our promising RTI F2 QD WEC technology justice. Sean Lewis of our RTI “mechanical team” has produced initial CAD 3D drawings of our 1/20 RTI F2 QD prototype. It is designed such that most key dimensions (and weight distributions) effecting performance can be modified as our RTI “hydrodynamics team” (Dick Ackers, Michael Macnicoll, and Toby Dewhurst) refine our F2 QD numerical model with the excellent data obtained during the Prize 1/50 scale test week at the new U. Maine Alfond W2 (Wind-Wave) Facility and use our updated model to optimize 1/20 scale F2 QD performance. We are one of several Wave Energy Prize teams who booked 1/20 scale model wave tank testing time at the Alfond W2 Facility.

    We were sorry to learn that Justin Stocker, the leader of our RTI “electronics & controls” team, will play a more limited role as he relocates to the west coast. We are pleased, however, that Rick Sparrold has joined our E&C team. Rick is recently retired from Raytheon Missile Systems where he was Senior Principal Electrical Engineer and spent his entire professional career after graduating from U. of Arizona as an EE. We are also considering additional electronics & controls team additions as we attempt to implement a challenging “adaptive control” strategy for our 1/20 scale RTI F2 QD.

    Rohrer Technologies, Inc. (RTI) has previously successfully built and wave tank tested two 1/25 scale RTI prior generation WECs (the G2 and F1) which preceded the F2 QD but they used less complex control systems and more comfortable time schedules.

Currently M3 is working closely with team member Glosten to refine the mooring dynamics models and structural systems. Carderock deployment concepts are underway with RPS Evans Hamilton (the same team member who oversaw M3’s APEX deployment in the Pacific Ocean in 2014).

  • The team is very excited to be continuing on in the Wave Energy Prize as first alternate! The time since the 1/50th scale testing has been filled with planning for the 1/20th scale model design, build and pre-testing. There are numerous design considerations that will need to go into the larger model and it is critical that we get it right. The representative PTO, data collection system and control system are all components that will change slightly given the revised scale, scope and available resources for this round. The team is also coordinating pre-testing to occur at a wave test facility which will give a baseline for testing if given the opportunity to test at Carderock. Below we have included a neat perspective of the 1/50th scale WEC from the bridge that spans the wave tank.

  • First, we have changed our name back to Mocean Energy from MOE. The name change came as a result of the formation of Mocean Energy LLC, a US company based in Maryland.

    M3 works on 1:20 scale design and welcomes new team member

    Posted on Mon 15 Feb 2016 by M3 Wave

    Since preparations for 1:20 scale testing are a long lead time item, we have commenced preparations for a Finalist “field campaign” as we await the selection process results.

    This month the team began developing the framework for designing, transporting, and deploying a 1:20 scale NEXUS.

    For pre-testing, we are undertaking a lengthy project to double the operational depth of our company wave tank to improve testing fidelity of deep water systems like NEXUS at 1:50 scale. Additionally, we secured a tentative Spring slot at a suitable 1:20 test facility for shakedown runs.

    M3 Wave is pleased to welcome a new Senior Scientist, Alice G., to the team. Alice will help with hydrodynamics and sediment modeling around submerged structures (like NEXUS anchor systems). Welcome Alice!

    Oscilla Power works on optimization of WEC device

    Posted on Fri 12 Feb 2016 by Oscilla Power

    Oscilla Power submitted its 1:20 build plan successfully at the end of January, and since then, we have continued to work on system optimization. We have identified specific improvements that should significantly enhance wideband power capture of the Triton WEC and there appears to be room for even further improvement, giving us a good shot at exceeding WEP’s ACE threshold in the 1:20 scale tests.

    Tim Mundon and Rahul Shendure will be at ICOE 2016 in Edinburgh, Scotland later this month where Tim will be presenting recent research results on Triton’s asymmetric heave plate. If you will be in Edinburgh, please drop by the Oregon Wave Energy Trust booth and say hello.

    Finally, we wanted to share a video that was taken during the 1:50 scale testing. While were running some additional tests, a glitch with the wave generators resulted in generation of a ‘rogue wave’ equivalent to a height of about 40m. The Triton model rode the wave without any problems and we were able to continue testing.

    IOwec making improvements while eagerly waiting for finalist announcement

    Posted on Fri 12 Feb 2016 by IOwec

    The preparation of the 1/20th Scale Building schedule, the BOM and the budget took quite a large portion of this month. Most of the energies were spent to find commercial components for our innovative device in order to fit the desired specifications and find the best balance between performance and cost. We are looking forward to receive the results of the tests at Stevens that did not evidence any big problem or failure (structural or functional) and of course keep our finger crossed for the judges’ response on Technology Gate 2 hoping to continue as finalist the adventure in this very demanding and inspired competition.

    In this eagerly waiting, we cannot stay with our hands folded, because we want to arrive at March 1st with the best IOwec possible configuration. In order to perfect every detail of the 1/20th prototype all the members are working hard for the last improvements, thanks to the experience gained in the 1/50th scale tank tests.

    The MIT team is working on a new time domain potential flow model with non-linear free surface conditions that will be used for the optimization of the floater shape and PRTT characteristics, as well as different active control strategies for the PTO, that will be allowed during the tests at MASK. The new potential flow model, in fact, is faster than a RANSE simulation and more accurate than the state of the art linear frequency domain methods like WAMIT or AQWA. In parallel, viscous, multi-physics, multi-body numerical simulations are running day and night to verify the new non-linear potential flow model.

    The Italian part of the team will come soon to Boston with the aim to work together with the MIT colleagues on the final optimization of the device and with the building activities.

    While waiting for the judges decision on the finalists, our team has been hard at work on business strategy efforts. Our technology team is continually adapting our WEC conceptual design in-sync with our continued deeper understanding of the future market requirements for WECs gained through discussions with renewable energy industry thought leaders. In this regards, we strongly recommend to other WEC developers Dr. Weber’s recent publication “WEC Technology Readiness and Performance Matrix - finding the best research technology development trajectory” for its insight into how early-phase technology decisions play an over-sized role in future business results and guidance on what should drive those early-stage decisions. It can be found on Dr. Weber’s Research Gate page Meanwhile, our intellectual property team is nearing completion on multiple patent applications, our marketing team will be launching our website soon, and our business development team is gaining traction in identifying opportunities for our first pilot project.


    SEWEC welcomes new team members

    Posted on Fri 12 Feb 2016 by SEWEC

    Team SEWEC is pleased to announce that Dr. Paul McEvoy has just joined our team. Paul is Technical Director at TFI Marine, a global leader in marine mooring systems and tethers and will bring us hard core knowhow in this area. We will use Paul’s expertise to both minimize mooring loads in survival conditions and to cross check our numerical simulations as we continue to optimize our adaptive control algorithms prior to (fingers crossed) 1/20th scale testing.

    In planning our 1/20th scale design/build we have been fortunate to secure the services of Peter Jeal – a versatile metalsmith based in San Francisco. Peter is not just a highly skilled craftsman with an artistic bent, but also eight times winner of the Folkboat Class Championship sailing USA-113 in San Francisco Bay.

    Team SeaPotential had the honor and privilege, as guest of the Tinker|Bristol Manufacturing Incubator and Makerspace, to visit with US Congressman David Cicillini (D. RI), and to share updates on our progress in the Wave Energy Prize. Our report included our expression of gratitude for, and excitement about, the support we are receiving from Tinker|Bristol, and through introductions made by Tinker, from Roger Williams University and the local marine manufacturing business community.

    The Congressman was especially pleased to hear of our ambitions to build an ocean energy research, development and manufacturing center based in Bristol and powering the world.

    Also, the University of Iowa, where Team SeaPotential tank tested our 1/50th scale model of the DUO, published this news item on their participation as a tank testing venue in the Prize Contest at

    As our team awaits the news in March, we continue to work on fine-tuning designs and drawings for a 1/20th scale model of our DUO wave energy converter and building stronger connections into the local marine manufacturing community here in Bristol, RI, which is already home to many leading edge marine materials and manufacturing companies, both for continued support in our hoped-for continued competition for the Prize, and looking beyond the Prize, to quarter and eventually full-scale DUO design, development, testing and deployment as an important contributor to a new energy economy for the United States and the world.

  • Super Watt Wave Catcher Barge Team

    SWWCB Teams develops 1:20 scale model

    Posted on Fri 12 Feb 2016 by Super Watt Wave Catcher Barge Team

    The Super Watt Wave Catcher Barge team has continued to made good progress with the following accomplishments since its last progress report:

    • As a result of the model test, the Team removed the hull’s stern rake which increased the flat bottom area of the barge by about 6% with only a small increase in the barge’s weight. This additional stern flat bottom area will increase the wave lift forces on the stern and the power output of the stern generators to better match the bow generators’ power output.

    • The Team updated the design of the mechanical equipment which resulted in a significant weight savings. Further equipment weight reductions are underway.

    • The Team submitted its 1-20th_Build_Plan_Template on January 29th as required by the Wave Energy Prize which included: 1/20th Scale Model Drawings in PDF and DXF format, updated installed costs, updated weights based on design changes, a demonstration video of the flywheel and recoil spring combination, a demonstration video showing the power of a recoil spring in pull back cars and complete CAD Models of the entire barge and its equipment.

    • The Team responded to DOE questions on its Newsletter.

    • The Team confirmed SWWCBT RST for TG2 with the Wave Energy Prize.

    • The Team has added Bridon International Ltd, Asian Star Anchor Chain Co., Ltd. and Orbital Traction.

    • The Team hopes to add ATI Integration, who are specialist in mechanical model building.

    • The Team hopes to soon add a mechanical engineering consultant who has been recommended who specializes in flywheel and recoil spring design. He will help us size the recoil spring and flywheel for optimum temporary torque storage, optimum weight and minimum costs.

    • Thanks to the 1/20th model scale, the Team is working on the design of the very light uni-directional pulley and a light recoil spring/flywheel combination based on readily available off-the-shelf mechanical components.

    • The Team will be sending formal requests for quotes out to potential hull and enclosure model builders with the updated 1/20th Scale Model drawings, weights, specs and scope of work. (One possible model builder
    has already seen the model and confirmed he can build the model in 6 to 10 weeks depending on his work load at the time and has provided a rough cost estimate.)

    • The Team will soon be sending inquiries out to potential barge model mechanical equipment detailed designers and fabricators for material procurement, fabrication and transportation of the mechanical equipment base on the new off-the-shelf component supply design concept.

    • The Team will soon be preparing a model testing plan and meeting agenda for an early kickoff meeting with MASK Model Basin personnel.

    The [email protected] MULLET was successfully tested at Stevens Institute (, in spite of an historic snowstorm delaying travel and closing the campus. Team members were all set to arrive in Hoboken on Sunday, January 24 for our week of scheduled Wave Energy Prize testing, but Mother Nature had other plans. Luckily, the folks from Blacksburg were able to reschedule their flights, and our Team Leader took the somewhat unorthodox move of driving to Hoboken in the snow, with his cat! All arrived to begin testing Tuesday. Unfortunately someone got left behind. Sue Sorlie, scheduled to take the train, was twice thwarted by Amtrak and had to concede defeat, unable to get to Hoboken at all.

  • Atlas Ocean Systems

    Atlas Ocean Systems refines system and works on business plan

    Posted on Wed 10 Feb 2016 by Atlas Ocean Systems

    January was an exciting month. We completed our 1:20th build plan and submitted it to the DoE. This activity was very educational and involved as we strove to create a 1:20th system that would demonstrate key concepts and generate data that will help finalize the control laws and design of the full scale commercial system. We planned for the multiple engineering challenges that the scale presents to allow our ballasting and bag systems to be fully controllable as they will be in full scale as well as accurate measurement and testing of the pneumatic systems. We also met with welding and machining shops to understand the construction methodology that will best suit the 1:20th needs. We are very pleased that the 1:20th turns out to be large enough to validate our pneumatic flexible systems using the same construction methodology as the full scale. This provides us with a surprise opportunity for early risk reduction!

    In parallel we continued to run analysis to help refine the necessary spread of ballast and bag control authority in support of the 1:20th design. We have run nearly 20,000 individual cases to generate our response functions!

    The remainder of our time has been dedicated to investor relations and business planning. We were privileged to present at multiple investment group meetings and have had extremely positive feedback. Along the way we have gained a handful of extremely valuable advisers that are helping us understand all that we need to do to be a successful investment candidate. We have had very good discussions with Naval Architects, testing facilities, turbine manufacturers, and ship yards. We continue to work to assembly the full scale development team and financing.

    As always our best wishes to all the competitors, March 1st is fast approaching!

  • RTI Wave Power

    RTI Wave Power designs for simplicity and cost

    Posted on Wed 10 Feb 2016 by RTI Wave Power

    Our RTI Wave Power Team was fortunate to complete its 1/50 scale model testing at the new U. of Maine Alfond Wind-Wave (W2) Facility on December 18th giving the team time over the Holidays to enjoy some well-earned relaxation.

    While the 1/50 scale modeling, design, build, and test schedule did not afford us the opportunity to test a fully optimized design, we were extremely pleased with our model performance during test week. In early January we started the design of our 1/20 scale model and specifying key components with longer delivery times. We look forward to receiving our test week data set so we can confirm the accuracy of our numerical model and use it to further improve our 1/20 scale model RTI F2 QD.

    Our WEC design features the simplicity and low cost of a single elongated wave front parallel surface float (which remains parallel to oncoming wave fronts). The F2 QD moves both upward and rearward on wave crests and forward and downward on ensuing wave troughs (for concurrent multi-mode heave and surge energy capture). Our patented float can be partially seawater flooded (to tune float mass to current wave conditions). It is fully flooded in severe seas allowing the float to rotate on its two swing arms (which are attached to our direct drive generator housed below the water line in our twin vertical spar frame) to the 6 o’clock position safely below wave troughs even in 25 meter seas. Our concave float rear surface, extending into its attached lower shoaling lip extension, protrudes deeply into the water column yet its motion creates no energy robbing “back wave”. This patented configuration provides major performance and cost advantages over other WECs using elongated wave front parallel surface floats (like the Salter Duck, Stingray, and Azura) which require massive costly central cylinders (or circular section floats).

Team leadership and structural model assembly takes place at the Advanced Research Institute in Hampton, while the Power-Take-Off (PTO) physical modeling group and integrated Numerical Modeling group are based in the Department of Aerospace and Ocean Engineering on our main campus in Blacksburg.

    The Advanced Research Institute in Hampton is located on the campus of the National Institute of Aerospace ( Our facilities include a high-bay lab with a still water tank that has a molded depth of 5 ft and a waterplane area of 7ft by 7ft. We inherited the lab and its tank from former Virginia Tech Associate Professor Leigh McCue, who last year was appointed Executive Director of the American Society of Naval Engineers ( While here, Dr. McCue used the tank in her research as well as giving local middle schoolers hands-on experience building and testing remotely operated vehicles in summer STEM camps.

    By adding synchronized, pulsating pumps to the tank (commercially sold to simulate wave flow in saltwater aquariums for coral-growing enthusiasts), we’ve been able to create a quite respectable standing wave having a height of 8 to 9 cm and a resonant period of 1.2 sec, which approximates one of the 1:50 monochromatic waves used in Stage 2 of the Wave Energy Prize competition.

    Team AquaHarmonics arrived at the University of Michigan just in time to enjoy some chilly winter weather. However, the world class climate controlled wave tank at the University of Michigan’s Marine Hydrodynamic Laboratory helped keep us focused on testing without having to bundle up. Working with Steve, Brent and Nick was fantastic and having a top notch support team made it so we were able to complete all our required testing with no issues by Thursday afternoon.

    We brought along our control system that we had shelved prior to starting work on the Wave Energy Prize and after accidentally frying a Rasberry Pi during and then finding a replacement at a local Radio Shack,we were up and running again Friday morning.

    The team managed to fit in an additional 20 runs with our preliminary control system! We look forward to receiving our terabyte of data from the testing and learning more about our device. We are now designing our 1/20th scale device and will continue working on our control system as well as revising our numerical analysis.

    Posted on Fri 15 Jan 2016 by Oscilla Power

    In January, Oscilla Power completed 1:50 model testing at the University of Maine. Real-time results suggested that we achieved excellent agreement with our numerical model and earlier tank testing. Staff at the University of Maine were extremely helpful during the testing, enabling everything to go very smoothly. Once the official testing was complete, we were able to spend extra time investigating alternate system configurations that will provide increased power capture at longer periods.

    Video of device in operation:

    We are currently completing the 1:20 model build plan for submission at the end of the month.

  • Testing occurred at the Davidson Laboratory at the Stevens Institute of Technology in Hoboken, NJ January 11-15, 2016. The model was inspected, assembled and verified on Monday and Tuesday and the model was placed in the wave tank for testing on Wednesday which concluded Friday. While the assembly and verification process took a significant amount of time and effort, the testing process went exceedingly smooth due to the hard work and dedication of the team at the Davidson Laboratory.

    The video below is of a polychromatic wave impacting the device during Thursday’s testing. The device is operating extremely well, even when encountering waves with high amplitudes and short periods. Ideally the device would be optimized via a tune-able damping system based on the waves encountered. Unfortunately for testing purposes, variable damping was not allowed. A significant challenge proved to be the impact of the cables to the data acquisition system. Even small forces from the cables yielded large impacts on the yaw angle of the device in relation to the incident waves.

    The team is very happy with the testing and is very thankful for the opportunity to test at the Davidson Laboratory. We are very much looking forward to future testing and refinement.

  • Super Watt Wave Catcher Barge Team

    SWWCB Team continues to make good progress

    Posted on Wed 13 Jan 2016 by Super Watt Wave Catcher Barge Team

    The team has continued to made good progress with the following major accomplishments:

    • The SWWCB Team completed its updated installed cost estimate which now includes: a Bridon Rope quote for the wire rope portion of the horizontal storm survival mooring system complete with connectors, testing, certification and delivery, an ASAC quote for chain portion of the horizontal storm survival mooring system complete with connectors, testing, certification and delivery, a Bridon Rope quote for the polyester rope vertical power generation mooring system complete with connectors, testing, certification and delivery, updated structural weight from the elimination of the barge’s stern rake which increases the power output of the stern generators to match the power output of the bow generators, improved and lighter articulated pulley system, new wave slam double bottom, etc. These changes did not significantly change our earlier cost estimates because the spring buoys are no longer required in the catenary horizontal mooring system. The SWWCB with four 6 megawatt direct drive wind turbine generators had significantly lower installed CAPEX or OPEX costs as compared to 4 separate 6 megawatt direct drive onshore wind turbine generators.

    • A capacity factor expert informed us that Super Watt Wave Catcher Barge should have a capacity factor close to 60% which is roughly double the capacity factor of 30 to 35% for onshore wind turbines also in ideal locations. The Super Watt Wave Catcher Barge’s higher capacity factor should enable it to produce almost twice the power, with lower installed CAPEX or OPEX costs than onshore wind power, making Super Watt Wave Catcher Barge a good choice over onshore wind turbines near significant wave areas.

    • The Super Watt Wave Catcher Barge included in the model test is a heavy weather location barge designed for 100 year storm survival in heavy weather locations like off the West Coast of Oregon and Washington. Lighter barges with possibly smaller direct drive wind turbine generators may be more appropriate in smaller wave environment locations like off the US East Coast or the US Gulf of Mexico.
