Floating foundation specialist Ideol has successfully installed the Floatgen floating wind turbine off the Atlantic coast of France.

Floatgen was towed to its installation location at the SEM-REV test site off Le Croisic on 30 April 2018, after which it was connected to pre-installed mooring lines laid on the seabed in July 2017.

Ideol said an episode of severe weather immediately after the floater was installed with 5 m waves and wind speeds of 15 m/s demonstrated its seakeeping characteristics and the accuracy of Ideolís simulation models.

Connection to the export cable and to the grid is due to be completed in the near future after a final series of tests.

The project brings together Ideol, which is responsible for the design of the floating system, including foundation, mooring system and export cable, and  the supply of the wind turbine; Centrale Nantes, which is providing engineering expertise and access to its offshore test site; Bouygues Travaux Publics, which built the foundation; the University of Stuttgart, which played a key role in the simulation work during the study phase;  RSK Group, which was responsible for the environmental impact analysis; Zabala, which is responsible for project management; and Fraunhofer-IWES, which undertook comparative analysis of the different floating solutions.

The project is supported by the European Union as part of the FP7 programme, the French Environment and Energy Management Agency and by the Pays de la Loire region.
