Advancing offshore wind infrastructure with cutting-edge subsea cable installation solutions
Asso.subsea, a leading offshore contractor specializing in subsea cable installation, in consortium with Hellenic Cables, has been awarded a turnkey contract by Réseau de Transport d’Électricité (RTE) for the Dunkerque Offshore Wind Farm. This project reinforces Asso.subsea’s expertise in delivering high-quality subsea cable installation, protection, and burial solutions to support France’s renewable energy transition.
The Dunkerque Offshore Wind Farm, with a planned capacity between 500 and 600 MW, will feature two 225kV HVAC export cable links, enabling the efficient transmission of clean energy to the French grid. Asso.subsea will be responsible for the transportation, installation, and protection of the submarine cable links, deploying state-of-the-art technology and highly specialized in-house-designed equipment. Hellenic Cables will manufacture and supply 32 km of submarine cables and 38 km of underground cables, along with all necessary accessories, and oversee jointing, testing, termination, and commissioning of the cable links.
The submarine cables will be manufactured at Hellenic Cables’ state-of-the-art facility in Corinth, Greece, while the land cables will be manufactured at Hellenic Cable’s onshore cable manufacturing facility in Thiva, Greece, also currently undergoing a capacity expansion programme.
Asso.subsea will utilize the expanded capacity of its state-of-the-art fleet, deploying specialized in-house-designed equipment to ensure precision, efficiency, and the highest quality standards throughout. The project involves complex laying and burial operations in shallow waters, an area where Asso.subsea has demonstrated extensive expertise over the years.
Alexandros Tziotakis, Chief Executive Officer at Asso.subsea stated: “We are proud to collaborate once again with Hellenic Cables and RTE on the Dunkerque Offshore Wind Farm, a landmark project that reinforces our shared commitment to advancing renewable energy infrastructure. Asso.subsea’s expertise in subsea cable installation and protection ensures the seamless integration of these critical components into the wind farm’s network. This project marks our return to France, following the successful completion of key projects such as Gruissan, Fécamp, Saint-Brieuc and PGL. It highlights not only our technical capabilities, but also our dedication to supporting Europe’s energy transition and sustainability goals. We look forward to delivering this project with the highest standards of quality, safety and reliability.”
Kostas Savvakis, General Manager at Hellenic Cables, stated: “This project is an important step forward in supporting France’s renewable energy goals and Hellenic Cables is honored to continue its collaboration with RTE. Our role in the Dunkerque Offshore Wind Farm highlights Hellenic Cables’ commitment to delivering reliable and sustainable energy solutions, while fostering strong collaborations with industry leaders like RTE and Asso.subsea.
