International classification society Bureau Veritas has issued Approval in Principle for the WindFloat Floating Offshore Wind Turbine (FOWT) foundation. WindFloat is designed by Principle Power and consists of a ballasted floating platform which supports a multi-megawatt wind turbine generator.

Matthieu de Tugny, Senior Vice-President and Head of Offshore, Bureau Veritas, says, “FOWT technology will help exploit clean renewable offshore wind power. It offers substantial advantages over fixed offshore wind turbines as the entire unit can be assembled ashore and FOWTs can be installed in deep water and areas with varied underwater landscapes. There is also a much lower environmental impact from their installation. Our expertise with the offshore floating structures and metocean conditions means we can ensure designs for new FOWTs will be safe, reliable and will produce power over the expected range of environmental conditions.”

The WindFloat is a floating platform that supports a multi-megawatt wind turbine generator. It is unmanned, and carries no significant quantity of pollutant substances. The platform is moored with a three-line catenary mooring system. It is a three-column platform, equipped with a closed-loop ballast system to compensate for changes in mean wind velocity and direction.

A first WindFloat prototype has been deployed in Portugal, 5 km off the coast of Aguçadoura, since 2011. To date the system has produced and delivered over16 GWh of electricity to the grid, demonstrating the concept feasibility without significant issues.

The second generation of WindFloat technology, addressed by the present Approval In Principle, is intended to be part of a pilot array of floating offshore wind turbines in the French Mediterranean sea, to be developed by ENGIE and EIFFAGE.
