Contract awarded for world’s biggest wind farm

Heerema Marine Contractors have been awarded a contract for the transport and installation of the Dogger Bank C offshore substation off the northeast coast of England.

Owners SSE Renewables, Equinor and Eni made the award as part of the third and final phase of the Dogger Bank project, which means total energy generating capacity will be 3.6GW combined with Dogger Bank A and B. This should be enough to supply 5% of the UK’s electricity demand, the owners say, powering six million homes.

For the 3,500-tonne jacket foundation, four main piles and  9,500-tonne offshore substation topside, Heerema will perform offshore lifting to position the jacket foundation on the scour bed, using main piles to provide on-bottom stability. 

The offshore substation will be lifted from a barge prior to the set-down on the jacket foundation.

”Inatalling sizeable offshore substations is core business for us and we are looking forward to working together on the preparation and installation of Dogger Bank C,” SAID Heerema’s wind director, Jeroen van Oosten.

Dogger Bank c is around 560 km² in area, and almost 200km from shore at its closest point.

SSE will lead the development and construction, and Equinor will operate the farm on completion for its predicted life of around 35 years.
