The contract for manufacture and supply of monopiles and transition pieces has gone to Smulders, the Belgian subsidiary of Eiffage Métal, as part of a consortium with Sif (a Dutch company specialised in offshore foundations).
As a result approximately 260,000 tonnes of steelwork for first two phases of the Dogger Bank offshore wind farm project in England will be produced in Smulders’ facilities in Poland and Belgium.
The contract is subject to financial close on the two phases, which is expected soon.
The Dogger Bank wind farm, a joint venture between SSE Renewables and Equinor, will be erected in the North Sea, 130km off from the Yorkshire coast of England. At 3.6 GW, it will be the largest offshore wind farm in the world, and is being developed in three phases: Dogger Bank A, B and C.
The first two phases, Dogger Bank A and B, will require 190 foundations in total. Each foundation comprises a monopile and a transition piece in water depths varying from 18 to 63 metres.
For this contract, Smulders will manufacture the secondary steel of the transition pieces, and will assemble, coat and test the fully equipped transition pieces. Sif will manufacture and supply the monopiles and primary steel for the transition pieces, and marshal all foundation components.
Production in Smulders’ facilities in Poland and Belgium will begin in May 2021. The assembly, which will be done at the Belgian Hoboken facility, is scheduled to last approximately 10 months. The first phase, Dogger Bank A, is expected to be operational in 2023.
