Dogger Bank Wind Farm and Seaway7 have completed installation of all 277 transition pieces on the three-phase, 3600MW project in the North Sea.
The partners said Seaway7’s Seaway Alfa-Lift installed the 87th and final unit at Dogger Bank C in late November, following 95 installations each at Dogger Bank A and B.
Seaway7 has installed 554 foundation assets in total, including 277 monopiles earlier in the programme.
Dogger Bank is being developed by SSE, Equinor and Vargronn.
Alan Evans, senior project manager on Dogger Bank Wind Farm, said: “Today we’re celebrating the safe and successful installation of more than 500 foundation assets across the three phases of Dogger Bank Wind Farm over the last three years.”
He said: “During this time, we’ve enjoyed a strong partnership with Seaway7 and its sub-suppliers who together, have navigated a hugely demanding and complex engineering challenge.”
He added: “We now have the solid foundations in place to support our 277 generating assets that will make a significant contribution to a cleaner, more secure and affordable renewable-led energy system.”
Bruce Willox, project and operations director at Seaway7, said: “Installing the foundations for the world’s largest offshore wind farm is an enormous achievement.”
He said: “Over the three years, hundreds of components and over a thousand lifts have been completed – representing a phenomenal scale in offshore construction.”
He added: “This project demonstrates what can be achieved through strong partnership, shared ambition, and the dedication of our skilled people working onshore and offshore.”
