Danish wind firm Ørsted said today that the first offshore export cable had been laid for the Hornsea Project One project.
Ørsted said Tideway BV had successfully put down the first section.
The Hornsea Project One development, located 120km of the Yorkshire coast, will be capable of generating 1.2GW when complete in 2020.
Ørsted say that the finished offshore wind project will produce enough energy to power one million homes.
The three high voltage subsea power cables will carry electricity from three offshore substations to shore.
Tideway BV is using Ocean Yield’s cable lay vessel Connector.
Tideway BV will also undertake engineering work, boulder removal, pre-trenching, pulling in cables to substations, crossing installation, offshore jointing and cable burial.
Duncan Clark, Hornsea Project One director, said: “We are pleased that Tideway has been able to mobilise the Connector to meet our specific requirements for this project, and we look forward to Living Stone coming to site to help build this remarkable wind farm project.”
Ken Swaegers, project manager, Tideway BV, said: “This is a very exciting job for us, and an amazing opportunity to work on the biggest construction project in offshore wind. Due to its scale we have several vessels operating at the Site, and over summer, the Connector will be accompanied by our own brand new cable laying vessel Living Stone.
“The Living Stone will be equipped with an innovative dual-lane cable installation system, consisting out of two cable highways – one for laying the cable and one where the next cable can be simultaneously prepared, significantly improving production rates.”
