Seaway7’s heavy-lift vessel, Seaway Alfa-Lift installed the 87th and final transition piece onto its corresponding monopile foundation at Dogger Bank C, the third phase of Dogger Bank, in late November 2025. This milestone followed the previous installation of 95 transition pieces at the Dogger Bank A and 95 at the Dogger Bank B phases of the project.
In total, Seaway7 has installed 554 foundation assets on the wind farm, following installation of 277 monopiles earlier in the construction programme, utilising Seaway7’s heavy lift vessel Seaway Strashnov.
