Jan De Nul Inks Orsted Hornsea 3 Export Cable Contract


Jan De Nul Group has signed the export cable contract for the Hornsea 3 offshore farm with Ørsted and will be responsible for the seabed preparation, transport, installation and protection of 350 km of DC export cables connecting the wind farm to the UK electricity grid.

“We are proud to support Ørsted in building the world’s largest individual offshore wind farm by connecting 2.9 GW of renewable energy capacity to the UK’s national grid,” says Wouter Vermeersch, Jan De Nul Group’s offshore cable manager. “Thanks to our collaboration with Ørsted, which includes recent projects such as the monopile installations for Gode Wind 3 and Borkum Riffgrund 3 in Germany, we keep on constructing the energy transition together.”

The company plans to deploy several vessels for the installation and protection of the two DC export cables. Isaac Newton and Connector will transport and install the cables. To protect the cables, a variety of burial solutions will be used. Work is expected to start next year, with a 2027 completion date.

The project is located 160 km off the U.K. Yorkshire coast. Its 2.9 GW capacity brings the total capacity of the Hornsea offshore wind zone to 5.4 GW.
