The work will include transporting and installing the 3,500t jacket foundation, four main piles, and the 9,500t 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.

Dogger Bank Wind Farm will be the largest offshore wind farm in the world when operational in 2026, with an overall capacity of 3.6GW. In total the wind farm is expected to generate enough renewable electricity to supply five per cent of the UK's demand, equivalent to powering six million homes and helping the UK government to reach its targets set for the desired transition to renewable energy.
