Heerema’s semi-submersible crane vessel Sleipnir has successfully installed the Hornsea 3 Link 1 Jacket and the offshore converter station (OCS1). Hornsea 3 offshore wind farm will be located 120 km off the coast of Norfolk, UK, and will be the largest offshore wind farm in the world.
These lifts showcased safe, efficient, and precise execution under typical North Sea conditions, supported by strong coordination across project management, engineering, and marine operations. Heerema Marine Constractor‘s project teams in Houston and Leiden were responsible for the operation, together with the crews of Sleipnir, Heerema’s anchor handling tugs Bylgia and Kolga, third party offshore vessels Island Champion and Boulder.
The Link 1 jacket was constructed by Heerema Fabrication Group (HFG) and was loaded out of the construction yard on 11 March. HFG is also constructing the second jacket, Link 2, which is to be completed in August 2026. Heerema will install the Link 2 jacket and OCS later this year.

About Hornsea 3
Hornsea 3, located 120 km off the Norfolk coast, is an £ 8.5 billion project that will deliver enough green electricity to power more than 3 million UK homes. Nearly 550 km of array cables will connect the wind turbines to two OCS platforms, where power is converted from alternating current (AC) to direct current (DC) for efficient transmission to shore.
