Offshore Wind
References
Following the award in November 2020 of contracts for Dogger Bank A and B, Dogger Bank Wind Farm has now signed with the Sif-Smulders consortium the contract for the fabrication and supply of all foundations for the Dogger Bank C phase of the project. In total, the consortium will build all 277 monopiles and transition pieces for Dogger Bank A, B & C.
Dogger Bank Wind Farm is being developed in three phases – Dogger Bank A, Dogger Bank B and Dogger Bank C – located more than 130km from the Yorkshire coast. Collectively they will become the world’s largest offshore wind farm when complete.
Dogger Bank A and B is a joint venture between SSE Renewables (40%), Equinor (40%) and Eni (20%). In November 2021 SSE Renewables and Equinor, 50:50 joint venture partners in Dogger Bank C, announced Eni will take a 20% stake in the final phase, with SSE Renewables and Equinor maintaining 40% stakes each, in a deal that is expected to complete in Q1 2022 (subject to Dogger Bank C Financial Close and regulatory approvals).
Dogger Bank C, like A and B, will have an installed generation capacity of 1.2GW. Combined, they will have an installed capacity of 3.6GW and will be capable of powering 6 million UK homes. Water depths at Dogger Bank vary up to 31 metres. Each foundation comprises a monopile and a transition piece.
In the project-specific Sif-Smulders consortium, Sif is responsible for fabrication and supply of monopiles and primary steel for the transition pieces, and for the marshalling of all foundation components at its Maasvlakte 2 Rotterdam terminal (picture below). Smulders will manufacture secondary steel and assemble, coat and test fully equipped transition pieces.
