DEME Bags Cable Contract for Dutch Wind Farm

DEME has won a “substantial” contract to transport and install inter-array cables and secondary steel for the 800-megawatt OranjeWind offshore wind farm in the Netherlands.

The Belgium-headquartered contractor said it would deploy offshore and cable installation vessels, a hopper dredger and fallpipe vessel, as well as supporting equipment, to handle some 114 kilometers of cables, which will connect all 53 foundations to a substation in the Dutch North Sea.

Starting in the second half of 2026, the project will include all engineering, preparation and supporting activities, ensuring DEME offers a “complete solution” to OranjeWind’s partners, RWE and TotalEnergies.

The cables themselves will be installed in areas with large sand waves to ensure they are buried at the required depth and stabilized with rock at the offshore substation and crossings of existing assets. The secondary steel scope of the contract calls for the transport and installation of boat landings, access platforms and internal platforms at the monopile foundations.

DEME values a “substantial” contract at 150-300 million euros.

“This latest contract award highlights DEME’s ability to provide a comprehensive range of solutions to the offshore wind industry. With our diverse offshore fleet and specialized equipment, we are well positioned to successfully deliver this project, while working closely with the RWE and TotalEnergies joint venture,” said Philip Scheers, general manager, subsea power cables at DEME.

“Additionally, the project will benefit from DEME's extensive experience in cable installation, particularly given the dynamic seabed environment at the wind farm location. We are also excited to collaborate with RWE and TotalEnergies, two leaders at the forefront of advancing the energy transition through innovative solutions.”


DEME, TotalEnergies and RWE are members of the Breakbulk Global Shipper Network, or BGSN, a worldwide network of companies and executives involved in the engineering, manufacturing and production of project cargo. The next in-person meet-up for BGSN members will be at Breakbulk Middle East 2025 in Dubai on Feb. 10-11.
