Wind energy – Dogger Bank OWF
Sif Netherlands, in a consortium with Smulders, has signed the contract for the manufacture of all 87 monopiles and transition pieces (approx. 130 kton steel) for the third phase of the Dogger Bank Wind Farm.
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.
The foundation fabrication and supply are subject to financial close on Dogger Bank C which is foreseen late 2021.
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. Dogger Bank C is expected to require 87 foundations. Water depths at Dogger Bank vary up to 31 metres. Each foundation comprises a monopile and a transition piece.
Sif is responsible for the 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. Smulders will manufacture secondary steel and assemble, coat and test fully equipped transition pieces.
Dogger Bank Wind Farm Project Director, Steve Wilson, said: “We’re delighted to expand our ongoing work with the consortium on the first two phases of the wind farm with this contract for DBC. 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.”
