It is based on the French Sea
For the first time in France, 22 km off the coast of Le Croisic (Loire-Atlantique), a wind turbine produces electricity at sea. The Floatgen wind turbine became fully operational on Tuesday 18 September 2018 and it has been realized by Ideol, a company specialized in floating foundations for offshore wind, while the project is being supported by the European Union as part of the FP7 programme, with a consortium composed by 7 European partners.
The 2 Mw floating wind turbine produces electricity capable of supplying the equivalent of 5,000 inhabitants. The technology is particularly innovative in its ring-shaped float: Ideol developed the world's first floating barge designed for offshore wind; the water thus forms a kind of swimming pool in the center of this square of 36 m. of side, which contributes to stabilize the structure.
For Ideol developers, Le Croisic site will test if technology works properly. Thus after €25 Mln. investment and one year of construction at the port of Saint-Nazaire, the 80 m/diameter wind turbine was towed in less than 12 hours to the site where the Ecole Centrale de Nantes had 3 weeks to install the 6 nylon cables required for attachment.
