A future offshore wind farm in Fécamp
Fécamp / France
Gravity-based foundations by Bouygues Travaux Publics in partnership with Saipem and Boskalis
With total capacity of around 500 MW, this offshore wind farm connected to the power grid should produce the equivalent of the domestic consumption of around 770,000 people, i.e. more than 60% of the inhabitants of the Seine-Maritime region. 71 wind turbines will be installed between 13 and 22 kilometres off the coast, on gravity-based foundations laid on the seabed at depths of 25 to 30 metres. Each weighing 5,000 tonnes, these foundations will ensure the stability of the wind turbines. Constructed in the Bougainville maritime works yard in the Grand Port Maritime of Le Havre, they will be transported by barge to the offshore wind farm site. Works began in June 2020 and are due to be completed in late 2022. The future Fécamp offshore wind farm will contribute to the diversification of France’s energy mix with low-carbon energy.

Further information
Kraftanlagen
Kraftanlagen, Bouygues Construction’s German subsidiary, is to be in charge of the extension and modernisation of the InfraLeuna power plant at the Leuna chemical complex. The contract, worth more than €100 million, is to secure the energy supply for the Leuna site and develop its energy capacity. The modernisation of the existing InfraLeuna power plant will provide a high-performance combined-cycle gas and steam turbine plant, with improved efficiency and flexibility.
VSL
VSL, a subsidiary of Bouygues Construction, has won a strategic contract for the Hywind Tampen project in Norway. The world’s biggest floating wind farm will also be the first to use prestressed concrete SPAR buoys. This technology is suited to deep water and makes it possible to place the wind turbines far off the coast, where the wind is faster and more regular.
