April 23, 2025, by Adnan Memija

After installing all 95 monopiles at Dogger Bank B, the offshore installation vessel Seaway Strashnov has moved on to the third phase of the UK’s Dogger Bank Wind Farm, where it has now begun foundation work at 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 work at Dogger Bank A, where wind turbine installation is currently underway.

Seaway Strashnov completed the installation of the remaining two monopiles, while Seaway Alfa Lift will return to the site to install the final five transition pieces (TPs).

On 22 April, Seaway Strashnov kicked off the same work on the third phase of the Dogger Bank Wind Farm, according to the latest notice to mariners. The monopile installation is expected to take place until approximately the fourth quarter of 2025.
