Smulders has revealed that, on 19 and 20 April, the first 4 of 95 transition pieces for the first phase of Dogger Bank Wind Farm were loaded out at its yard in Hoboken. The transition pieces were shipped to Sif’s Maasvlakte 2 terminal in Rotterdam.

The Dogger Bank transition pieces each have a diameter of 8 meter and weigh about 550 tons. That makes these transition pieces the widest and heaviest transition pieces ever manufactured in Hoboken.

In November 2020, the consortium Sif-Smulders was awarded the contract for the manufacture of all 190 monopiles and transition pieces for Dogger Bank A & B, the first two phases of Dogger Bank Wind Farm. In late 2021, the consortium was also awarded the contract for the third phase of the wind farm, Dogger Bank C.


Located off the north-east coast of England, Dogger Bank Wind Farm is being built in three 1.2 GW phases,
Dogger Bank A, Dogger Bank B, and Dogger Bank C. It is poised to be the largest offshore wind farm in the world when operational, with an overall capacity of 3.6 GW.

Dogger Bank Wind Farm is a joint venture partnership between SSE Renewables (40%), Equinor (40%), and Eni (20%). SSE Renewables will to lead on the development and construction of Dogger Bank Wind Farm, and Equinor will operate the asset on completion.  

Once the three phases are complete, the project is expected to generate around 18 TWh annually, enough renewable electricity to supply 5% of the UK’s demand and equivalent to powering six million UK homes.

Onshore construction began in 2020 and is currently underway for
Dogger Bank A and Dogger Bank B, with offshore construction on Dogger Bank A due to begin in Q2 2022. First power is expected in Summer 2023 and Summer 2024 for Dogger Bank A and B respectively, with commercial operations to follow around 6 months later.

Onshore cable installation civil works for
Dogger Bank C will start in Q1 2022, with construction of the onshore convertor station to commence in Q2 2022. Offshore export cable installation will commence in Q1 2024 with offshore platform installation to commence in Q2, 2024. Foundation installation will commence in Q3, 2024 while turbine installation will commence in Q2, 2025. First power is anticipated in Q3, 2025 and full power in Q1, 2026.
