‘Completion of Subsea Cables Installation at French Floating Wind Pilot by Asso.subsea’

Asso.subsea, a subsea cable services company, has successfully completed the cable installation, burial, and protection operations for the 25 MW Provence Grand Large floating offshore wind project in France in partnership with Prysmian Powerlink. The project, located in the Mediterranean Sea and developed by EDF Renewables and its partners, is a floating wind pilot project aimed at demonstrating the economic viability of offshore floating wind farms.

Asso.subsea was responsible for all marine works, including engineering, cable loading, route preparation, installation, and configuration of cables, as well as Horizontal Directional Drilling (HDD) operations for the landing point. The company covered a cable distance of approximately 21,000 meters, connecting France’s inaugural floating offshore turbines to the Port-Saint-Louis-du-Rhône station and generating electricity equivalent to the consumption of 45,000 people.

To carry out the operations, Asso.subsea utilized CLV Atalanti and TSV Argo vessels, along with the AssoJet III Mk2 jetting ROV. The specially designed vessel CLV Atalanti played a crucial role in navigating the challenges of the shallow waters at the 780-meter landing point in Port-Saint-Louis-du-Rhône.

Owned by Parc Eolien Offshore de Provence Grand Large, a subsidiary of EDF Renewables in partnership with Enbridge Eolien France 2 (EEF2), the floating wind farm features three tension leg floaters supporting 8.4 MW wind turbine generators supplied by Siemens Gamesa.

The Provence Grand Large project is expected to produce the annual equivalent of electricity consumption for 45,000 inhabitants. Dimitris Panagos, Director of Offshore Wind at Asso.subsea, expressed pride in the company’s contribution to France’s first floating wind farm, emphasizing their commitment to innovation, sustainability, and the green transition.
