Ocean Winds (OW) has announced the successful installation of the first turbine foundation at the Dieppe–Le Tréport offshore wind farm (EMDT), marking a key milestone for France’s offshore energy transition. Located 17 km off the coast of Dieppe and 15.5 km from Le Tréport, the project will ultimately include 62 turbines, generating renewable electricity equivalent to the consumption of around 850,000 people.
The installation follows the completion of the project’s offshore substation earlier this summer. Each foundation consists of a steel jacket structure, fabricated in Spain and transported via the port of Cherbourg using DEME’s installation vessel Innovation. Depending on water depth, the jackets measure between 48 and 55 metres in height and are anchored into pre-installed piles up to 63 metres long.
Strengthening France’s offshore wind industry
The Dieppe–Le Tréport project highlights the growth of France’s offshore wind supply chain, with turbine components manufactured in Le Havre and logistics coordinated through regional ports. Ocean Winds said the development reflects its commitment to supporting a competitive and resilient national offshore wind sector while contributing to European decarbonisation targets.
Marc Hirt, Ocean Winds’ Country Manager for France, said: “Ocean Winds has been committed to the French offshore wind market for more than a decade, across all maritime façades and technologies. With Dieppe–Le Tréport, we are adding another major step to our industrial footprint, with more than 1 GW of capacity currently under simultaneous construction in France.”
Next steps
Frédéric Flaus, Project Director of EMDT, said: “The successful installation of this first foundation marks the start of a new chapter in the construction of the Dieppe–Le Tréport wind farm. It is the result of close collaboration between our teams and partners. We now look forward to the safe installation of all 62 foundations, continuing through to 2026.”
Alongside the Dieppe–Le Tréport project, Ocean Winds is progressing with the Yeu-Noirmoutier (EMYN) and the floating Éoliennes Flottantes du Golfe du Lion (EFGL) projects. Together, these developments represent more than 1 GW of offshore wind capacity under construction, expected to provide clean energy to over two million French households each year.
