Carillion has won a £30M contract to design and build the UK’s longest onshore connection for an offshore wind farm cable in Norfolk.
Dudgeon Offshore Windfarm Ltd appointed the firm to design, supply, install and test the 47km cable system, which runs Weybourne, on the coast, to Necton. It will serve the Dudgeon Offshore Wind Farm, which is being built 32km off Cromer.
The cable will connect the subsea cable that will take the power from the offshore wind turbines to a new National Grid sub-station. The contract will involve the design, supply and installation of 288km of 132kV cable and associated jointing accessories.
As part of the project, Carillion will undertake all civil engineering and cable installation activities, including crossing a number of watercourses and strategic roads using trenchless techniques. The project is the longest of its type ever delivered in the UK.
The onshore cabling project will start later this year and is scheduled to be commissioned in 2016.
Graham Carr, managing director of Carillion Network Services said: “We are delighted to have been selected for this complex contract to deliver the onshore cabling project for the Dudgeon Offshore Windfarm. This project builds on the excellent relationship that Carillion has developed with Statoil and Statkraft.”
Dudgeon Offshore Windfarm is a joint venture between Statoil, Statkraft and Masdar, which will invest approximately £1.5bn in the offshore windfarm. It aims to provide enough energy to power 410,000 homes each year.
