Enersea has completed the detailed design of two offshore substation jackets for the Hornsea 3 offshore wind farm.

The two jackets, Link 01 and Link 02, weigh approximately 3,500 tonnes and will support offshore substations of around 9,000 tonnes. Heerema Fabrication Group is responsible for the EPC scope of the jackets and subcontracted the detailed engineering work to Enersea.

Enersea’s scope covered the detailed structural design of the jackets and engineering support during the fabrication phase. The company said close collaboration between all parties contributed to an efficient fabrication process and swift progress of the structures.

Link 01 was successfully installed last week. Link 02 is progressing towards completion, which is anticipated in August 2026.

Project developer Orsted, which is developing the Hornsea 3 offshore wind farm, awarded the EPC contract for the complete substations to Aibel. Aibel subcontracted the EPC contract for the jackets to Heerema Fabrication Group and is developing the topsides itself.

Hornsea 3 will be one of the world’s largest offshore wind farms once operational, supporting the continued expansion of offshore renewable energy capacity in the UK.
