Abu Dhabi Future Energy Company (Masdar) and ScottishPower Renewables have completed a major construction milestone at the £4-billion ($5.4 billion) East Anglia THREE offshore wind farm, with all 95 foundations now installed off the Suffolk coast.

Weighing 1,200-1,800 tonnes, and standing 67-84 m tall with a diameter of up to 10.6 m, the monopiles are the largest to be installed from a jack-up vessel in Europe.

The installation of all 95 transition pieces – 20 m in height, 8 m in diameter and weighing more than 400 tonnes – has also been completed.

With turbine installation already under way, offshore and onshore construction will continue at pace over the coming months, clearing the way for East Anglia THREE to become fully operational by the end of 2026, delivering 1.4 GW of home-grown clean power to the UK.

Once operational, East Anglia THREE will provide 1.4 GW of clean energy, helping to meet rising demand and strengthen the UK’s energy security, he added.

East Anglia THREE is Masdar’s first 50:50 offshore wind joint venture in the UK.

The project has consumed more than 200,000 tonnes of steel anchored spot on into a seabed area the size of almost 43,000 football pitches.

The turbines with huge 115-m blades are the biggest built and here in the UK.

The project supported thousands of jobs during construction and around 100 jobs delivered during the windfarm’s lifetime.
