Ocean Winds has installed the offshore electrical substation for its 496MW Dieppe-Le Tréport wind farm in the English Channel.
The operation marks the first major offshore construction milestone for the scheme, one of three Ocean Winds projects now under build in France.
Chantiers de l’Atlantique designed and built the topside in Saint-Nazaire, with the jacket supplied by Navantia.
Heavy-lift vessel Gulliver, operated by DEME, carried out the installation.
The platform will gather power from 62 turbines and export it ashore through grid links developed by RTE.
“Ocean Winds is adding momentum to France’s offshore sector,” said country manager Marc Hirt.
Chantiers director Frédéric Grizaud said the lift concluded “24 months of fabrication” and strengthens the yard’s renewables credentials.
Project director Frédéric Flaus said the milestone brings the venture “a step closer to delivering clean energy to the region”.
Dieppe-Le Tréport, owned by Ocean Winds, Sumitomo Corporation and Banque des Territoires, will supply electricity for about 850 000 people once fully operational.
