WindFloat 1 Prototype (WF1) Floating Wind Farm

28 Sep 2016: Principle Power announces the successful completion of the project. At an event held in conjunction with the WindEurope Summit in Hamburg, Principle Power announced the successful decommissioning of WindFloat 1. The project, originally installed in 2011, was a full lifecycle demonstration of the features and benefits of the WindFloat floating offshore wind foundation concept, and featured a Vestas V-80 2MW turbine. Fabricated using the local supply chain and fully assembled and commissioned ashore, the WindFloat was then towed 400km to its project site, where it ultimately delivered over 17 GWh of energy to the grid and successfully operated through waves that at times exceeded 17m and winds of over 60 knots. In July 2016, having completed all of its project objectives, Principle Power initiated the WindFloat decommissioning process. The WindFloat foundation was detached from its mooring lines and electrical cable, and then towed back to Southern Portugal’s Port Sines facility, where the wind turbine was dissembled. This was the first time an offshore wind turbine had been dismounted from a floating structure and it demonstrated the procedures to be used in commercial projects in the event of unanticipated major component failure. The turbine has now been transferred to another project and the inspections reveal that the WindFloat foundation itself is in excellent condition. “The WindFloat’s very successful 5-year deployment, in the open ocean of the Atlantic, has proven that the technology can meet its promise and is ready for commercialization,” said Joao Metelo, Principle Power’s President and CEO. “The simplified assembly and installation, in addition to the ability to tow the unit to shore in the event of major maintenance issues, represents a sea-change in the way offshore wind can be done. The WindFloat reduces risk, and cost, for deep or transitional depth offshore wind projects.” Principle Power is now completing design for the WindFloat Atlantic project, a 25 MW project planned for deployment off of Northern Portugal which is backed by a consortium of major energy and industrial players including: EDP Renewables, Trust Wind (a 50/50 JV between Engie and Marubeni), Chiyoda Corporation, Mitsubishi Corporation and Repsol.
