Seaway7 awarded contract for world’s second-largest offshore wind farm worth up to $750 million

(WO) – Subsea 7 S.A. confirmed the award to Seaway7, part of the Subsea7 Group, of a very large contract by ScottishPower Renewables for the transport and installation of the foundations and inner-array cables for the East Anglia THREE offshore wind farm. According to a company statement, the contract is worth between $500 million and $750 million.

East Anglia THREE – located in the Southern North Sea, 69 kilometers off the Suffolk coast – will be the world’s second largest wind farm when it begins operation in 2026. Its 95 14.7MW turbines will have a combined capacity of 1,400MW, generating enough green electricity to power the equivalent of more than 1.3 million homes.

Seaway7’s scope of work includes the transport, logistics and installation of 95 monopile foundations, associated seabed preparation and scour protection along with the engineering, supply and installation of the 95 inner-array cables. In addition to the heavy lifting and cable lay vessels, Seaway7 will also utilize its heavy transportation fleet to handle the significant transportation scope.

Ross Ovens, ScottishPower Renewables’ Managing Director for the East Anglia Hub offshore windfarms, said, “We’ve been moving at pace to put all the building blocks in place to ensure East Anglia THREE can get to work as quickly as possible, producing more green electricity in the UK, for the UK. I’m very proud that there’s more of the same to come while driving that transition to a cleaner, greener net zero future alongside partners like Seaway7.”
