Danish energy company Ørsted has revealed that the first offshore export cable section has been laid at Hornsea Project One by Dutch construction company Tideway.

The project will see the installation of three high-voltage subsea power cables that will carry electricity from three offshore substations to shore.

For laying the first cable at the wind farm located 120km off the Yorkshire Coast, Tideway is said to have used Ocean Yield’s Connector cable lay vessel.

In addition to cable laying, Tideway will also be responsible for engineering, boulder removal, pre-trenching, pulling in cables to substations, crossing installation, offshore jointing and cable burial.

“This is a very exciting job for us, and an amazing opportunity to work on the biggest construction project in offshore wind.”

Tideway project manager Ken Swaegers 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.”

Upon completion, Hornsea Project One will be the first wind farm in the world with a capacity exceeding 1GW, which is enough to power more than one million homes in the region.

The project is expected to commence operations by 2020.

Hornsea Project One director Duncan Clark 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.”
