Team Info

Principle Power will be co-led by Antoine Peiffer and Sam Kanner.

Principle Power is a small company that has a proven track record in offshore renewable energy. The engineering team designed and led the construction of the WindFloat-1 platform, the world’s first semi-submersible floating wind platform. Since 2003, the team has specialized in cutting-edge offshore engineering problems involving complex hydrodynamics. The innovative solutions utilize a proper mix of essential ingredients that include understanding of our client’s needs, hard work, expertise and creativity. Principle Power is excited to take on the challenge of producing electricity from the ocean’s waves.

Principle Power is excited to explore this new area in offshore renewable energy technologies. Developing clean energy from the ocean will help the US meet its obligations to generate carbon-free, cost-effective electricity. With experience in designing many types of floating platforms (wind, oil and gas, etc), Principle Power is uniquely positioned to leverage its existing competencies, including hydrodynamics, structural dynamics and fabrication and installation experience. The WindFloat technology was chosen as a Phase 2 selection of the DOE’s Offshore Wind Advanced Technology Demonstration Projects, which confirms their ability to provide innovative solutions backed up by sound engineering analysis. Floating offshore wind platforms and wave energy devices must overcome many of the same challenges in order to reliably operate in such a harsh environment. Ushering in a new era in the offshore energy industry requires a diverse set of experiences and networks within the offshore engineering community. Principle Power has the track record to deliver.

Team Bios

Sam Kanner

Sam Kanner is currently finishing his dissertation in Naval Architecture/Ocean Engineering from UC Berkeley on innovative concepts for floating offshore wind platforms. Specifically, his research involves the use of vertical-axis wind turbines on floating platforms to reduce the capital cost of these floating platforms. After graduation he will become an offshore engineer in the Research and Development Team at Principle Power. He has authored or co-authored numerous publications and conference papers on wave energy and floating wind turbines and was formerly a research intern in the Wind and Water Program at Sandia National Laboratories.

Dominique Roddier

Dr. Dominique Roddier is Principle Power Chief Technology Officer, and the co-inventor of the WindFloat. He obtained his doctorate in Naval Architecture from UC Berkeley, and after working in Houston in the offshore division of ExxonMobil’s Upstream Research Company co-founded Marine Innovation & Technology, a marine engineering consulting firm, which developed the Minifloat hull concept, and provided consulting services to ocean related industries. Additionally to Offshore Wind, Dominique is an expert in floating structures and has interests in spar vortex induced vibrations, LNG sloshing in large carriers, and wave energy conversion. He is actively involved in the ASME OMAE Conference management and in SNAME. He also serves as associate editor of multiple journals in the field of offshore engineering and has published extensively in this field.

Alexia Aubault

Alexia Aubault joined Principle Power (formerly Marine Innovation & Technology) in 2005 and is currently the Engineering lead of Principle Power. A graduate of Ecole Nationale Supérieure de Techniques Avancées, a Technology Institute of ParisTech, in Paris, France, she had just earned a Master in Ocean Engineering at the University of California, Berkeley. She has worked on global design of floating structures, complex hydrodynamic modeling and structural loading and analysis. She has been involved in oil and gas conception analysis as well as renewable energy projects. She carried out structural studies for the MiniFloat and WindFloat and was lead structural engineer during the design and onsite fabrication of the WindFloat prototype. In her spare time, Alexia pursues her fascination for the ocean through sailing.

Antoine Peiffer

Antoine Peiffer joined the engineering team of Principle Power (formerly Marine Innovation and Technology) in September 2009 and currently holds the position of Senior Naval Architect, with a double focus on turbine modeling and offshore installation. He is a passionate advocate of marine renewable energies, notably offshore wind and wave power. He received his MS in Mechanical Engineering from the University of California at Berkeley under the Ocean Engineering and Naval Architecture program. Antoine is delighted to be given the opportunity to work on an innovative marine renewable energy technology that will be deployed in the real world. During his free time, Antoine enjoys all the outdoor activities that the Bay Area generously offers, notably mountain biking, surfing, kite-boarding, and tennis.

  • Principle Power continues work on 1:20 scale model

    Posted on Wed 10 Feb 2016

    We have been busy finalizing the design for the 1:20 scale model as well as contacting potential suppliers to manufacture these large pieces. All of our PTO components can be purchased from pneumatic and electrical suppliers. However, we have found that the hull structure may have to be welded or glued together using various parts. Although we anxiously await the judges’ decision on Technology Gate 2, we are hopeful that we can continue on our path to help America obtain a cleaner energy future!

  • Principle Power completes testing at Oregon tank facility

    Posted on Thu 14 Jan 2016

    After weeks of anticipation over the holidays to begin testing, we finally arrived in Corvallis to find…. rain. Coming from drought-stricken California, it was a bit of a shock, but thankfully all of the researchers at the Hindsdale Wave Research Lab gave us a warm welcome. We were duly impressed with their experience, knowledge and professionalism in running a world-class wave tank and tsunami basin. We hope to return in the near future as it was a delight to work with them. Although we hit some bumps along the way, after a long week of installing, troubleshooting and testing the wave energy device, we are relieved to be finishing with this ‘labor-intensive’ part of the application. Here is a video of one of the runs. Go Beavers!
