Construction contract for 1.36 GW offshore wind project in UK

Subsea 7 S.A. has been awarded a contract for the installation of the entire inner array grid cable system of the 1,386 MW Hornsea Two offshore wind project developed by Optimus Wind Ltd., a subsidiary of the Ørsted Group.

The Hornsea Two offshore wind farm project is located approximately 90 kilometers off the Yorkshire coast within the UK sector of the North Sea. The offshore wind farm consists of 165 wind turbine generators, each with a capacity of 8.4 MW.

Subsea 7 will work on the inner array grid cable system that consists of 165 66kV copper-core submarine composite cables with a total length of more than 420km. In addition to the submarine cable installation works, Seaway 7 will also undertake a pre-installation submarine cable route survey, perform pre-installation boulder clearance activities and execute post-lay trenching services.

Project engineering will commence immediately and offshore activities are due to commence in 2021.

Once operational, the offshore wind farm will be able to provide power to 1.3 million homes.

Steph McNeill, Subsea 7’s SVP Renewables and Heavy Lifting, said: “We look forward to continuing our collaborative relationship with Ørsted to install the entire inner array grid cable system on the Hornsea Two offshore wind farm project. This award follows on from our reliable performance and successful completion of the installation activities for the Hornsea One offshore wind farm project earlier this year.”
