Prysmian connector for Gruissan offshore array

14 September 2021

Prysmian Group, in a consortium with Asso.subsea, a submarine installation specialist, has signed a contract worth approximately €30 million with RTE, Réseau de Transport d'Électricité, for the development of an export submarine power cable system for the Gruissan floating offshore wind farm located in Southern France.

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

All submarine 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 planned for the end of November, and commissioning scheduled for July 2023. 

Asso.subsea will undertake the installation services for the project, including all marine works such as cable loading, route preparatory works, and cable installation and protection.
