Dogger Bank Wind Farm and its delivery partner Seaway7 have achieved a major construction milestone with the installation of the final transition piece, marking the completion of all foundation work on the colossal three-phase offshore wind project in the North Sea.

The final transition piece, the 277th overall, was installed onto its corresponding monopile foundation at Dogger Bank C in late November, utilising Seaway7’s heavy-lift vessel, Seaway Alfa-Lift. This final installation followed the earlier completion of 95 transition pieces at Dogger Bank A and 95 at Dogger Bank B.

In total, Seaway7 has installed 554 foundation assets on the wind farm over the last three years. This figure includes the successful installation of all 277 monopiles, which were completed earlier in the construction programme using the heavy-lift vessel Seaway Strashnov.

Alan Evans, Senior Project Manager on Dogger Bank Wind Farm, hailed the achievement: "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."

Bruce Willox, Project and Operations Director at Seaway7, highlighted the scale of the work: "Installing the foundations for the world’s largest offshore wind farm is an enormous achievement. Over the three years, hundreds of components and over a thousand lifts have been completed—representing a phenomenal scale in offshore construction."

The completion of this work means the solid foundations are now in place to support the project's 277 generating assets, which will make a significant contribution to a cleaner, more secure, and affordable renewable-led energy system for the UK.
