The offshore installation vessel Seaway Strashnov has installed all but two monopile foundations at the Dogger Bank B offshore wind site in the UK and will return in the second quarter of 2025 to complete the installation.
Five more transition pieces (TPs) are also left to be installed, according to the latest notices to mariners from the project.
The monopiles and TPs at Dogger Bank B are being installed by Seaway Strashnov and Seaway Alfa Lift under contract OHT, now part of Seaway7 , secured for Dogger Bank A and B in the summer of 2020. The following year, Seaway7 was awarded a contract for the same work on the third phase of the Dogger Bank Wind Farm, Dogger Bank C.
Seaway Strashnov and Seaway Alfa Lift commenced the installation work at Dogger Bank B in the spring of 2024, after completing the first phase.
The monopiles and TPs, on top of which 95 GE Vernova’s 13 MW Haliade-X turbines will be placed, were manufactured by Sif and Smulders, who are also the suppliers for the other two phases.
A total of 277 monopiles and TPs will be installed across all three phases of the Dogger Bank Wind Farm. The first two 1.2 GW phases, Dogger Bank A and Dogger Bank B, will each comprise 95 Haliade-X 13 MW turbines. The third phase, Dogger Bank C, will feature 87 Haliade-X 14 MW turbines.
Dogger Bank Wind Farm, the world’s biggest offshore wind farm under construction, is owned by SSE Renewables (40 per cent), Equinor (40 per cent), and Vårgrønn (20 per cent).
