Cable lay begins at Hornsea Project One wind farm

The first offshore export cable section has been laid at the Hornsea Project One wind farm off the English coast.

Three high-voltage subsea power cables will carry electricity from three offshore substations to shore from the wind farm, which is located 120 kilometres off the Yorkshire coast.

Tideway is carrying out the cable lay, using a bespoke back-deck cable-lay spread on Ocean Yield’s vessel Connector.

Project Manager Ken Swaegers said Connector will be accompanied by Tideway’s new cable-laying vessel Living Stone, which is equipped with a dual-lane cable installation system.

In addition to cable installation, Tideway’s contract includes engineering, boulder removal, pre-trenching, pulling in cables to substations, crossing installation, offshore jointing and cable burial.

When operational in 2020, Hornsea Project One will be the first wind farm in the world with a capacity of more than 1GW and capable of providing clean electricity to more than one million homes.
