Ocean Winds (OW), an international company dedicated to offshore wind energy and created as a 50-50 joint venture by EDP Renewables and ENGIE, announces the successful installation of the offshore electrical substation for the Dieppe – Le Tréport offshore wind farm (EMDT), project in consortium with Sumitomo Corporation and Banque des Territoires.
This important milestone represents a decisive step forward in the offshore construction of the project and an achievement made possible by close collaboration between experienced French and European industry leaders. Designed and built by Chantiers de l’Atlantique at its Saint-Nazaire shipyard, the substation highlights the strength of the French offshore wind industrial sector. Its foundation, a steel jacket structure, was supplied by Navantia in Spain, and the installation operation at sea was carried out by DEME with its installation vessel Gulliver.
Once operational, the substation will collect the renewable electricity generated by the wind farm’s 62 turbines and transfer it to shore via the grid connection infrastructure developed by Réseau de Transport d’Électricité (RTE), operator of the French national electricity transmission system.
Marc Hirt, Country Manager for Ocean Winds in France, declared: “Following the first power of the EMYN project earlier this month and our continued progress on EFGL, the successful installation of the Dieppe – Le Tréport offshore substation is another significant milestone for Ocean Winds, and a further demonstration of the momentum building across France’s offshore wind sector. It also reflects the trust placed in us by the French State to contribute to the country’s energy transition, supported by a robust French and European industrial supply chain.”
The complex offshore operation was completed over several days, bringing together expert teams from the project, its contractors, and partners.
Frédéric Grizaud, Director of the Marine Energies Business Unit at Chantiers de l’Atlantique, said: "This extremely precise and well-prepared phase ends 24 months of construction of the Dieppe-Le Tréport topside at our Saint-Nazaire site. Through this project, we continue to strengthen Chantiers de l’Atlantique’s position as a key player in marine renewable energy in Europe. We are thankful to Eoliennes en mer Dieppe Le Tréport for their trust, as well as to all the teams involved. Now their mission goes on with the completion of offshore works, testings, and then the energization of the substation."
Frédéric Flaus, Project Director for Dieppe – Le Tréport, added: “This milestone is the result of months of rigorous preparation, technical expertise, and close coordination between all those involved. The arrival and installation of the substation not only marks the start of the project’s visible presence at sea but also brings us a step closer to delivering clean, renewable energy to the region. I want to thank our teams, partners and suppliers for their dedication and professionalism in delivering this decisive phase safely and successfully.”
Once fully operational, the Dieppe – Le Tréport offshore wind farm will generate electricity equivalent to the annual consumption of around 850,000 people, supporting France’s renewable energy ambitions and strengthening Europe’s offshore wind leadership.
