Hellenic Cables will supply inter-array cables for the Eoliennes en Mer Dieppe Le Tréport OWF in France





Brussels, 31 August 2023


Cenergy Holdings announces that Hellenic Cables, its cables segment, recently signed a contract with DEME Offshore, a leading offshore energy contractor, for the supply of inter-array cables for the Eoliennes en Mer Dieppe Le Tréport (EMDT), an offshore wind farm in France, located off the coast in the English Channel and expected to be commissioned in 2026. The EMDT OWF is a joint venture between Ocean Winds, Sumitomo Corporation and Banque des Territoires.

Hellenic Cables was entrusted with the responsibility of designing, manufacturing, and supplying the 66kV inter-array cables and associated accessories that will interconnect the wind turbines and connect them to the offshore substation. The scope of supply involves approximately 120km of 66kV inter-array cables with XLPE insulation. Manufacturing operations are scheduled to take place at the state-of-the-art factory of Hellenic Cables in Corinth, Greece commencing in 2025, with delivery expected to take place in the second semester of 2025.

With a total installed power of 496 MW, the offshore wind farm is located 15km off the city of Tréport and 17km off the city of Dieppe. Its 62 wind turbines will supply with electricity 850,000 people every year, the equivalent of two thirds of the inhabitants of Seine-Maritime department, or more than all the inhabitants of the Somme department.

Philip Scheers, Business Unit Director Cables at DEME Offshore, said: “DEME Offshore and Hellenic Cables have already established a fruitful collaboration on several large-scale offshore wind projects. With our combined expertise and commitment to excellence, we look forward to delivering this project safely and successfully.”
