Jan De Nul hires Correll for 1 GW Thor offshore wind farm in Denmark

Correll, part of SPIE Group, has been awarded a contract by Jan De Nul to complete the 66 kV inter-array cable (IAC) termination and testing on wind turbines for RWE’s 1 GW Thor offshore wind project in Denmark.

The works are planned to commence in July 2025 with the mock-up scheduled for November 2024.

RWE signed up a Jan De Nul-Hellenic Cables consortium for the supply and installation of the entire cable system for the 1 GW offshore wind farm.

Under the contract, Hellenic Cables and Jan De Nul will manufacture and install 60 kilometers of export cables on the 30-kilometer-long cable route from the offshore wind farm to shore and approximately 200 kilometers of inter-array cables.

Offshore installation and commissioning of the cable system are expected in 2025.

The two companies are also in charge of delivering and installing the onshore cables from the landfall to the onshore substation, delivered by Siemens Energy, which is working with MT Højgaard Danmark on the civil engineering and construction work.

The offshore wind farm, located around 22 kilometers from Thorsminde on the west coast of Jutland, will feature Siemens Gamesa SG 14-236 DD wind turbines installed on monopile foundations. Of the 72 turbines at the Thor offshore wind farm, 40 will be equipped with recyclable rotor blades.

At the beginning of October, Axess Technologies secured a cable installation contract with HSM Offshore Energy for the 1 GW project.

The work is expected to start in the first quarter of 2025 at HSM’s Schiedam yard in the Netherlands.

Once fully commissioned in 2027, the project will become Denmark’s largest offshore wind farm and will be capable of producing enough renewable electricity to supply the equivalent of more than one million Danish households, said Correll.
