Located off the coast of Le Croisic in Brittany, Floatgen is the first 2 MW floating wind turbine in France. This project, launched in 2013, brings together seven European partners including BW Ideol, which designed the entire floating system (the foundations, the anchoring system and the configuration of the electricity export cable) and supplies the wind turbine, Centrale Nantes engineering school, which provides its expertise in ocean engineering, supplies the anchoring system and makes available its SEM-REV sea trial site, and Bouygues Travaux Publics, which built the floating foundation. For this project, Bouygues Travaux Publics developed a specific formulation of lightweight, self-compacting concrete to build the foundation, as well as innovative construction methods on three coupled barges. Connected to the national electricity grid, Floatgen has been operational since September 2018.
