Sif-Smulders consortium to manufacture Dogger Bank C foundations

A consortium of Sif Netherlands BV and Smulders Projects Belgium NV has confirmed a contract to manufacture all 87 monopiles and transition pieces for Dogger Bank C, the third phase of the Dogger Bank Wind Farm project in the North Sea, off the Yorkshire coast. The contract depends on Dogger Bank C reaching financial close, which is expected by the end of the year. The Sif-Smulders consortium already holds contracts on Dogger Bank A and B, so it is now supplying for the whole project.

Sif will fabricate and supply the monopiles and primary steel for the transmission pieces, as well as marshalling all foundation components at its Maasvlakte 2 Rotterdam terminal. Smulders will manufacture secondary steel as well as assembling, coating, and testing fully equipped transmission pieces.

“We’re delighted to expand our ongoing work with Sif and Smulders on the first two phases of the windfarm with this contract for DBC"
, said Steve WIlson, Project Director for the Dogger Bank Wind Farm project. "The consortium will supply monopiles and transition pieces that are among the largest to be installed on any offshore wind farm and which continue to push the boundaries of foundation design.”

Earlier today, 4C Offshore
revealed who will be transporting and installing these foundations: Seaway 7 ASA.

The 3.6 GW Dogger Bank project is to be built in three 1.2 GW phases (A, B, and C), in the North Sea, 130 km off the coast of Yorkshire. In November 2021, Dogger Bank C’s 50/50 joint venture partners, SSE Renewables and Equinor, announced that Eni will take a 20% stake, with SSE Renewables and Equinor maintaining 40% stakes each. That deal will complete in Q1 2022, again subject to financial close and regulatory approvals.
