Team Info

The IOwec team will be led by Stefano Brizzolara.

The IOwec team is born thanks to the collaboration between the MIT Sea Grant College Program, the Politecnico di Torino, the experience of the company Wave for Energy and the Florida Atlantic University.

The team leverages previous experiences in the industry and created a WEC technology for installation in coastal areas as well as offshore. The main focuses of the team are in the reduction of Capital Expenditure and minimization of Maintenance operations for the technology.

The team experience in the offshore sector draws back to more than 10 years ago. Professionals within the team have acquired high expertise in WEC designing, prototyping, testing and overall assessment.

With expertise in mechatronics, hydrodynamics, electrical and ocean engineering the team works with a multidisciplinary approach to tackle one of the world most demanding challenges: producing electricity from the ocean with high levels of reliability and at low costs able to meet grid parity requirements.

Team Quote

Water covers more than 70% of our world.

Why do we want to make it greener, if we can have a world more blue.

The Ocean is still an almost unexplored source of sustainable energy production. The IOwec team wants to exploit the power contained in oceans and seas to provide energy to many different offshore applications and supply the world demand of renewable energy. These are almost new markets, but the available quantity of energy is vast.

With more than 60% of the US population living along or very close to the West and East Coast, the IOwec team strongly believes that the proposed WEC technology can become a reliable and strategic source for all the activities carried on by our country in those areas. The technology, in fact, has been devised with the simplicity and : no articulation or moving parts in direct contact with water; the main system components taken individually are well proven, highly reliable and mature technologies; finally, the engineered overall system results highly flexible/adaptable (capacity of converting energy from characteristic sea states of different application areas) and safe/reliable.

Team Bios

The IOwec team is composed by members of the MIT Sea Grant College Program, the Politecnico di Torino and the Florida Atlantic University.

Dr. STEFANO BRIZZOLARA, Assistant Director for Research of MIT Sea Grant, with more than 15 years experience in naval architecture and ocean engineering.

Dr. GIULIANA MATTIAZZO, Assistant Professor at the Politecnico di Torino, CEO of Wave for Energy, with 20 years experiences in Mechatronics and renewable energy.

Dr. MANHAR DHANAK, Director of The Institute for Ocean and Systems Engineering (SeaTech) at Florida Atlantic University, having served as the chair of the Department of Ocean Engineering for the past six years. He is also a professor in the newly formed Department of Ocean and Mechanical Engineering with research interests in hydrodynamics and physical oceanography.

  • IOwec making improvements while eagerly waiting for finalist announcement

    Posted on Fri 12 Feb 2016

    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.

  • IOwec tests at Stevens Institute

    Posted on Fri 15 Jan 2016

    The holidays are already gone and the IOwec team has come back to work more motivated than ever!

    The great experience gained by testing the 1:50 scaled device at the Steven’s Laboratory in New Jersey has infused a new and greater zeal to pursue the goal of the Prize.

    Currently the team is working on the 1:20 scale prototype carrying out modelling activities and is starting by contacting different suppliers to be ready for the next step of the Prize.

    In February the MIT colleagues will join the rest of the group at the Politecnico in Turin in order to work side by side as done at Steven’s in December.
