Dogger Bank Wind Farm and delivery partner Seaway7 have installed all 277 transition pieces on the 3600 MW Dogger Bank Wind Farm, marking the completion of all foundation installation work on the 3-phase offshore wind project in the North Sea.  

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 Wind Farm, 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 the successful installation of 277 monopiles earlier in the construction programme, utilising Seaway7’s heavy lift vessel Seaway Strashnov. Dogger Bank is being developed by SSE, Equinor and Vargronn.
