Prysmian Group and Asso.subsea have signed a contract worth approximately €30 million with Réseau de Transport d'Électricité (RTE) for the development of an export subsea power cable system for the
Gruissan floating offshore wind farm in Southern France.

Prysmian Group will be responsible for the design, supply, termination, testing, and commissioning of one 66 kV three-core subsea export cable with EPR insulation for a total of 25 km and attached another 66kV subsea dynamic cables with EPR insulation for about 1 km connecting the shore to a floating sub-station. The group will also provide additional 3 km of onshore 66 kV cables with XLPE insulation.


All susbea cables will be produced at Prysmian Group’s facility in Nordenham (Germany), while the land cables will be manufactured at the Gron plant in France. The notice to proceed is expected by the end of November. Commissioning is scheduled for July 2023.


Asso.subsea will undertake installation services. Asso.subsea will design and perform all marine works required for the project, such as cable loading, route preparatory works, cable installation and protection and HDD works at landfall.

The project is located 16km off the Languedoc-Roussillon in waters around 55 metres in depth. It will have an overall capacity of 30 MW.
