Offshore staff
ELEFSINA, Greece — Asso.subsea and partner Prysmian Powerlink have completed the cable installation, burial and protection operations for the Provence Grand Large Floating Offshore Wind Project.
This project, developed by EDF Renewables and its partners, is located 17 km off the coast on a 100-m deep site in the Mediterranean Sea.
Asso.subsea's scope of work included all marine works, such as engineering, cable loading of export and inter-array dynamic cables, route preparation, cable installation and configuration of lazy wave, burial, and protection, along with horizontal directional drilling operations for the landing point.
By covering a cable distance of about 21,000 m, Asso.subsea connected France’s inaugural floating offshore turbines to the Port-Saint-Louis-du-Rhône station, generating electricity equivalent to the consumption of 45,000 people.
Asso.subsea said its deployment of the CLV Atalanti vessel was pivotal to tackle the challenges of the 780-m landing point at the shallow waters of Port-Saint-Louis-du-Rhône. The vessel was converted in 2023 for this project to create the required cableway for the dynamic cable installation.
TSV Argo, engineered for global operations and equipped to support various subsea trenching vehicles, also assisted the team in navigating challenging environments.
The project also utilized the company's AssoJet III Mk2, which are jetting ROVs with a 1.5-kW of total power that are designed for deepwater subsea burial operations.
