The offshore wind farm will be located between 13 and 22 kilometres off the coast of Fécamp in Normandy. The 71 wind turbines will be connected to the gravity-based foundations installed on the seabed at depths between 25 and 30 metres.
Within the consortium, Bouygues Travaux Publics and Saipem are tasked with the design, construction and installation on the seabed of the gravity-based foundations with an individual weight of up to 5,000 tonnes necessary to provide the stability of the 7MW wind turbines. Boskalis is tasked with the design and preparation of the seabed rock foundation prior to GBS installation, and the scour protection and ballasting of the GBS’ after installation on the seabed.
The foundations will be constructed in the Bougainville maritime works yard in the Grand Port Maritime of Le Havre and will be transported by barge to the offshore wind farm site.
