Atlantique Offshore Energy, GE and SDI complete fabrication of Fécamp substation


Atlantique Offshore Energy, Chantiers de l’Atlantique Business Unit dedicated to Marine Energy, just finalised the design, construction, outfitting and onshore commissioning of the Offshore Substation (OSS) which will be soon installed at
Fécamp offshore wind farm.

For this project Atlantique Offshore Energy worked in consortium with GE Grid Solutions and SDI, part of DEME Group. The consortium has previously delivered the substation for the
Saint-Nazaire project which was installed in August last year. It is also responsible for the delivery of the substation and foundation for the Calvados offshore wind farm.

With a capacity of 480 MW the order for the
Fécamp OSS, including the topside and jacket, was places in June 2020. Construction kicked off shortly after in September 2020. The topside weighs around 2100 tonnes with the jacket weighing around 1 600 tonnes. Both are to be installed this summer.

Atlantique Offshore Energy stated that these works have mobilised over the last two years more than 450 persons in Pays de la Loire region. It outlines the new OSS benefits from lessons learned through the execution of previous projects.

Having reached this milestone, Frédéric Grizaud, Atlantique Offshore Energy Managing Director, commented: ”The Sail-Away of this new OSS demonstrates once again our ability to deliver successfully turn-key projects for all our customers, in France and worldwide. Our teams are very proud to be part of this growing Industry and to support the European energy transition. We are reinforcing our efforts through recruitment campaigns, with several job positions opened and accessible to different profiles”.

Bertrand Allanic, Director of Fécamp Offshore Windfarm for EDF Renewables, said: “Since its beginning in 2020, the construction of the windfarm is on schedule. We are happy to reach today another important milestone alongside our partner Atlantique Offshore Energy, division of Chantiers de l’Atlantique, with the finalization of the onshore activities for the OSS. The teams are now preparing its installation off Fécamp coastline planned during summer time. The mobilization of more than 450 persons in Pays de la Loire Region over the last 2 years, for the completion of this key component of the windfarm, reinforces the development of the French Offshore Wind Industry; an effort EDF Renewables and its partners are proud de be part of”.

The
Fécamp 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 gravity-based foundations installed on the seabed at depths between 25 and 30 metres. It is expected to produce the equivalent of the domestic electricity consumption of approximately 770,000 people, representing more than 60% of the inhabitants of the Seine-Maritime area. It is being developed by Eolien Maritime France (a joint venture between the French company EDF Energies Nouvelles and the Canadian company Enbridge) and wpd offshore.
