Seaway 7 to provide additional installation vessel at Dogger Bank offshore wind farm

Dogger Bank Wind Farm has entered into an agreement with Seaway 7, part of the Subsea 7 Group, to charter a second turbine installation vessel to support the ongoing delivery of the offshore wind farm off the coast of England.

This contract signing follows on from the earlier reservation agreement between Dogger Bank Wind Farm and Seaway 7 announced in December 2024.

Under the contract, the jackup installation vessel Seaway Ventus will commence turbine transport and installation work of GE Vernova Haliade-X offshore wind turbines at the Dogger Bank site in mid-2026.

This contract represents additional work for Seaway 7 at the Dogger Bank development where the company already has the contracts for transport and installation of the monopile foundations and transition pieces on all three phases of the project, with the works on Dogger Bank A complete and the works on Dogger Bank B substantially complete.

Turbine installation and commissioning work is continuing at Dogger Bank A, with completion of the first phase of the offshore wind farm expected in the second half of calendar year 2025.

SSE Renewables said that, when fully complete, Dogger Bank will be the world’s largest offshore wind farm, capable of powering around six million UK homes annually.

Dogger Bank Wind Farm is a joint venture between SSE Renewables (40 per cent), Equinor (40 per cent) and Vårgrønn (20 per cent). SSE Renewables is leading construction of the project on behalf of the three joint venture partners.

Equinor will be lead operator of the wind farm on completion for its expected operational life of around 35 years.
