UK, England, Norfolk: ScottishPower Renewables has announced the completion of the foundation works for the East Anglia Three offshore wind farm substation, a key stage in the 1.4 GW project located 74 km (46 mi) off the Norfolk coast.
Heerema Marine Contractors’ semi-submersible crane vessel Sleipnir carried out the installation of pin piles and jacket foundations between 9 and 18 August. The operation followed its earlier work at the Inch Cape offshore wind farm in Scotland, where the same vessel installed a jacket foundation and platform.
The Sleipnir will return to East Anglia Three in November to install the substation topside, which typically weighs between 1,200 and 3,000 t.
Onshore, one of the project’s main export cables has already been pulled ashore at Bawdsey, Suffolk. From there, the cable will connect to a converter station in Bramford, near Ipswich. In total, up to four subsea export cables will link the offshore platforms to the onshore grid infrastructure.
Once operational in early 2027, East Anglia Three will comprise 100 turbines producing 1.4 GW of clean energy, enough to supply more than 1.3 million homes.
The project has secured a 15-year Contract for Difference (CfD) under the UK government’s AR4 and AR6 allocation rounds, providing revenue stability and supporting delivery of one of the largest offshore wind developments in the UK.
