Belgian offshore construction and dredging company Jan De Nul Group has announced a major contract with Ørsted for the export cable component of the massive Hornsea 3 offshore wind farm in the UK.

Jan De Nul Group’s responsibilities will include seabed preparation, transportation, installation, and protection of a staggering 350 km of DC export cables. These cables will serve as the vital link connecting the wind farm to the UK’s national electricity grid.

The Hornsea 3 wind farm, situated about 160 km off the Yorkshire coast, is set to become the world’s largest individual offshore wind farm. It boasts a capacity of 2.9 GW, which will bring the total capacity of the Hornsea offshore wind zone to an impressive 5.4 GW.

The project will feature two DC export cables with a combined length of 350 km. It is estimated that Hornsea 3 will generate enough renewable electricity to power 3.3 million UK households.

“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,” said Wouter Vermeersch, manager of offshore cables at Jan De Nul Group.

The project, set to commence in 2025, will engage several vessels for the installation and protection of the DC export cables. The Isaac Newton and Connector vessels will be responsible for the transportation and installation of the cables, while the Simon Stevin vessel will install up to 150,000 tonnes of rock to safeguard the cables. The project is slated for completion in early 2027.
