World's Largest Crane Vessel Sleipnir Returns to East Anglia Three Wind Farm for Key Milestone
The world's largest semi-submersible crane vessel, Heerema Marine Contractors' Sleipnir, is set to make a significant contribution to the East Anglia Three wind farm project in the UK. The vessel, which completed the installation of the jacket foundation for the offshore substation in August, is scheduled to return to the site around 17 October to place the offshore substation (OSS) topside on top of the jacket foundation.
The East Anglia Three wind farm, a joint venture between ScottishPower Renewables and UAE-based Masdar, is expected to begin initial operation in the fourth quarter of 2026. The project will comprise 95 Siemens Gamesa 14+ MW wind turbines, generating a total capacity of 1.4 GW.
The offshore construction of the wind farm started in April 2023 with the installation of the first monopile foundation. The installation of the topside of the Offshore Substation, a crucial step in the project's development, is expected to take place around October 2025, with Sleipnir performing this vital task.
The upcoming topside installation by Sleipnir marks a key milestone in the East Anglia Three wind farm project. Once operational, the wind farm is set to make a significant contribution to the UK's renewable energy sector, furthering its commitment to reducing carbon emissions.
