114km of wires to connect 800MW Dutch wind farm’s 53 foundations to offshore substation
DEME has been awarded a contract to carry out the transport and installation works for the inter-array cables and secondary steel for RWE and TotalEnergies’ 800MW OranjeWind offshore wind farm in the Netherlands.
The Belgian contractor will transport and install a total of 114km of wires, which will connect all 53 foundations to the offshore substation in the Dutch North Sea and the project scope includes all the engineering, preparation and supporting activities.
Pre-sweeping will be conducted at the wind farm, situated 53km from the Dutch coast, before cable installation in areas with significant sand waves to ensure the wire is buried at the required target depth.
At the offshore substation and crossings of existing assets, the lines will be stabilised with rock.
The secondary steel scope includes the transport and installation of boat landings, access platforms and internal platforms at the monopile foundations.
“This latest contract award highlights DEME’s ability to provide a comprehensive range of solutions to the offshore wind industry,” said general manager subsea power cables at DEME Philip Scheers.
He added: “With our diverse offshore fleet and specialised equipment, we are well positioned to successfully deliver this project, while working closely with the RWE and TotalEnergies joint venture.
“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.”
Scheduled to start in the second half of 2026, DEME will deploy offshore and cable installation vessels (pictured), a hopper dredger and fallpipe vessel, as well as additional supporting equipment.
This is the fourth cable project the company has been awarded in recent months.
It won two contracts from Prysmian for the engineering and installation works for TenneT’s IJmuiden Ver Alpha and Nederwiek 1 offshore grid systems in the Netherlands.
As well as this, a consortium consisting of DEME and Hellenic Cables, won a major contract for the supply and installation of the high-voltage subsea cables for the Princess Elisabeth Island in the Belgian North Sea. |
