Heerema bags offshore substation contract for dogger bank wind farm

Heerema has won an offshore substation contract for the world’s biggest offshore wind farm Dogger Bank Wind Farm.

Owners SSE Renewables, Equinor, and Eni have awarded Heerema Marine Contractors a contract for the transport and installation of the Dogger Bank C offshore substation.

The work will include transporting and installing the 3,500 metric tonne jacket foundation, four main piles, and the 9,500 metric tonne offshore substation topside. Heerema will perform offshore lifting to position the jacket foundation on the scour bed, using main piles to provide jacket on-bottom stability. The offshore substation will be lifted from a barge prior to the set-down on the jacket foundation.

This project is part of the third phase of the world-leading Dogger Bank Wind Farm project, a joint venture offshore wind farm being constructed off the north-east coast of England by partners SSE Renewables, Equinor, and Eni. Due to its size and scale, Dogger Bank is being built in three consecutive 1.2GW phases; Dogger Bank A, Dogger Bank B, and Dogger Bank C. Dogger Bank C is around 560km² in size and at its closest point is 196km from shore. SSE Renewables is leading the development and construction of Dogger Bank Wind Farm while Equinor will operate the wind farm on completion for its expected operational life of around 35 years.
