The consortium of Hellenic Cables, the cables segment of Cenergy Holdings, and Jan de Nul have been selected by RWE to deliver the complete package for the submarine and onshore export cable system along with the inter-array cable system for Denmark’s largest offshore wind farm.

With a planned capacity of more than 1,000 megawatts, Thor will be built in the Danish North Sea, approximately 22 km from Thorsminde on the west coast of Jutland. Once fully operational, which is planned no later than end of 2027, Thor should be capable of producing enough green electricity to supply the equivalent of more than one million Danish households.

The turnkey project for the Thor Offshore Wind Farm includes the design, manufacturing, supply, transportation, installation, jointing, termination, and testing of the 275 kV HVAC export cable system and the 66 kV inter-array cable system. The export cable system consists of two 30 km offshore cables, onshore cables with a total length of approximately 26 km, and related accessories. The inter-array cable system comprises approximately 200 km of submarine cables and associated accessories.

The cables will be produced at Hellenic Cables’ vertically integrated, state-of-the-art submarine cables plant in Corinth, Greece. Highly qualified and experienced personnel following best working practices ensure the delivery of high-quality products and services. Cable production will be phased through 2023-2025 according to the project’s delivery plan.

Jan De Nul will take care of transporting and installing the export and inter-array cables using its Cable Laying Vessel Connector and will protect the offshore cables by burying them under the seafloor using one of its powerful subsea cable trenches.

Pål Coldevin, Executive Vice President Offshore Development Nordics, Poland & Baltics at RWE Offshore Wind: “With Thor, we will massively contribute towards Denmark’s ambitious climate targets. In order to deploy this offshore project, we will rely on our track record of more than 20 years in offshore wind and on experienced suppliers, like Hellenic Cables and Jan de Nul.”

Alexis Alexiou, CEO of Cenergy Holdings: “We are honoured that RWE selected Hellenic Cables in cooperation with our partner Jan De Nul for Thor Offshore Wind Farm. With more than 70 years of experience and knowledge to complete some of the most emblematic projects worldwide, we are convinced that Hellenic Cables will meet all the project requirements and contribute substantially towards Denmark’s ambitious climate targets.”

Wouter Vermeersch, Manager of Offshore Cables at Jan De Nul Group: “We are pleased to extend the successful cooperation between Jan De Nul and Hellenic Cables to support RWE in building the largest offshore wind farm in Danish waters. Our versatile vessels are ideally suited to install both the export as well as the inter-array cables in the challenging North Sea environment on the West coast of Denmark.”
