Wedoany.com Report-Aug. 27, ScottishPower Renewables announced that the steel structure for the HVDC offshore converter station at the East Anglia Three offshore wind farm has been installed in the southern North Sea. The four-legged jacket foundation, weighing about 3,700 tonnes and standing 59 metres high, has been fixed to the seabed at a depth of 36 metres, located 69 kilometres off the Suffolk coast.

The installation was carried out by Heerema Marine Contractors’ SSCV Sleipnir, one of the world’s largest crane vessels. The structure was transported from Aker Solutions’ fabrication yard in Verdal, Norway, before being positioned and secured at the site. Supporting vessels in the operation included tugs Bylgia, Skandi Handler, EEMS Wrangler, and the guard vessel Tess.

East Anglia Three is a £4 billion ($5.4 billion) offshore wind project and will have a capacity of 1.4GW once operational. It is planned to become the largest offshore wind farm within Iberdrola’s portfolio and among the largest worldwide. Scheduled to start operations by the end of 2026, the wind farm will provide enough electricity to supply more than one million homes.

Pedro Fernandez, East Anglia Three Project Director at ScottishPower Renewables, highlighted the importance of this achievement: “The offshore construction programme for East Anglia THREE is the biggest feat of engineering we’ve ever undertaken – to see 3,500 tonnes of steel lifted safely and securely into place, with exacting and medical precision, is a truly impressive sight. This is the latest milestone for the project and is testament to the tremendous teamwork with our supply chain partners, so my thanks to everyone involved from ScottishPower, Aker Solutions and Heerema.”

The project represents a major step in advancing the UK’s offshore wind capacity, combining large-scale engineering with international collaboration. The converter station is a crucial part of the development, ensuring that the electricity generated offshore can be transmitted efficiently to land. The jacket installation marks one of the key milestones in a broader construction programme that will continue over the next two years.

With its large capacity and advanced infrastructure, East Anglia Three is expected to strengthen renewable energy supply in the UK and demonstrate the role of offshore wind in meeting long-term energy needs. Its scale places it among the most significant renewable projects in Europe, and the progress achieved so far underscores the coordinated efforts of multiple international partners.

The successful installation of the converter station foundation signals strong momentum in the project’s construction phase, with further milestones planned as the wind farm moves toward its targeted 2026 completion. At full operation, East Anglia Three will not only supply clean energy but also support energy transition goals by complementing the UK’s renewable power generation portfolio.
