France: DEME has successfully installed the offshore substation (OSS) for the 496 MW Dieppe Le Tréport offshore wind farm, positioning it 15 km off Le Tréport and 17 km off Dieppe, France.

Designed and built by Atlantique Offshore Energy, a division of Chantiers de l’Atlantique, the substation arrived in Le Havre in June. Its jacket foundation is 54 m tall and weighs around 1,900 t. It was constructed at the Puerto Real shipyard in Spain and supplied by Navantia. DEME executed the offshore installation using its heavy-lift vessel, Gulliver.

“This extremely precise and well-prepared phase ends 24 months of construction of the Dieppe-Le Tréport topside at our Saint-Nazaire site,” said Frédéric Grizaud of Chantiers de l’Atlantique, highlighting the company’s growing role in European marine renewable energy.

Once commissioned, the substation will collect electricity from 62 Siemens Gamesa 8 MW wind turbines and feed it to the French grid via infrastructure developed by Réseau de Transport d’Électricité (RTE).

The Dieppe Le Tréport project is developed by Eoliennes en Mer Dieppe Le Tréport (EMDT), a joint venture of Ocean Winds, Sumitomo Corporation, and Banque des Territoires.

Marc Hirt, Ocean Winds’ Country Manager in France, emphasised the significance: “The successful installation of the Dieppe – Le Tréport substation is another major step for France’s offshore wind progress and Ocean Winds’ expanding presence.”
