February 4, 2025, by Adnan Memija

DEME’s installation vessel Apollo has completed the pre-piling campaign at the 496 MW Dieppe Le Tréport offshore wind farm in France.

Starting in June 2024, the campaign involved the transport and installation of 248 pin piles at the site located 15 kilometres off the city of Le Tréport and 17 kilometres off the city of Dieppe.

DEME said that the company is now gearing up for the jacket installation phase, scheduled to begin this summer.

The firm carried out work on Dieppe Le Tréport under a contract from 2023, which covers the transport and installation of the pin piles and jacket foundations for the wind farm’s 62 Siemens Gamesa 8 MW wind turbines.

DEME will also carry out the transportation and installation of the offshore substation’s pin piles, jacket, and topside. In addition, the company is responsible for the EPCI scope of 120 kilometres of inter-array cables.

The pin piles and the jacket foundations for the wind turbines and the offshore substation are being delivered by a consortium between the Spanish manufacturers Navantia Seanergies and Windar Renovables.

The Dieppe Le Tréport offshore wind farm is owned by the consortium formed by the Spanish company Ocean Winds, the Japanese company Sumitomo Corporation, and the French financial institution Banque des Territoires.

The project will have a generating capacity of 496 MW, enough to supply some 850,000 people with sustainable electricity per year from 2026.
