Fécamp Offshore Substation Completed and Ready to Go

Atlantique Offshore Energy has completed the construction of the offshore substation for the 500 MW Fécamp wind farm offshore France.

According to the company, a marine energy business unit of Chantiers de l’Atlantique, the offshore substation will soon be installed at the project’s site located more than 13 kilometres off the Normandy coast.

“ 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”, said Bertrand Allanic, Director of Fécamp offshore wind farm for EDF Renewables.

The company secured a contract for the construction of the substation in 2020, together with its partners GE Grid Solutions and DEME Group’s SDI.

Atlantique Offshore Energy was in charge of the topside and jacket foundation design, manufacturing, and onshore commissioning. Under a contract signed last year, the company will also be responsible for the maintenance of the offshore substation.

GE Grid Solutions was in charge of high and medium-voltage electrical equipment and protection control systems design, manufacturing, and commissioning, while SDI is responsible for the transport and installation.

The OSS jacket foundation is being manufactured by Rosetti Marino, which cut the first steel for the jacket at the beginning of last year, while Chantiers de l’Atlantique kicked off the construction of the topside in September 2020.

The four piles for the OSS jacket foundation were installed by DEME Offshore’s jack-up vessel Sea Installer in April 2022, with the foundation coming up next.

The Fécamp offshore wind farm will feature 71 Siemens Gamesa SWT-7.0-154 wind turbines, all of which will stand on gravity-based foundations, the first of which was completed at the Grand Port Maritime of Le Havre at the beginning of this year.

The offshore wind farm is being built by EDF Renouvelables, EIH Sarl, a subsidiary of Enbridge, and wpd.

Offshore construction is scheduled to be completed and the wind farm fully commissioned by the end of 2023.
