transport and installation of inter-array cables… transport and install a total of 114 kilometres of inter-array cables
DEME was awarded a contract by OranjeWind (the RWE and TotalEnergies joint venture) to carry out the transport and installation of the project’s inter-array cable system and associated secondary steel at the OranjeWind offshore wind farm (Hollandse Kust (west) Site VII) in the Dutch North Sea, about 53 km off IJmuiden. Offshore work was scheduled to start in the second half of 2026. Under the contract, DEME was set to transport and install a total of 114 km of inter-array cables that connect the 53 turbine foundations to the offshore substation. DEME’s scope also included engineering, preparation and supporting activities required to deliver the complete cable installation solution in a dynamic seabed environment. In addition to cable lay and burial activities, DEME planned to undertake pre-sweeping at the wind farm site in areas with significant sand waves to help achieve the required target burial depth. At the offshore substation interface and at crossings of existing assets, the cables were planned to be stabilised with rock. DEME’s secondary steel scope covered the transport and installation of items such as boat landings, access platforms and internal platforms at the monopile foundations. The contract value was described by DEME as falling within its “substantial” range (EUR 150–300 million).
