Heerema awarded Hornsea 3 offshore converter stations transport and installation contract

Aibel has contracted Heerema Marine Contractors to transport and install two offshore converter stations (OCS) for the Hornsea 3 offshore wind farm. The Hornsea 3 offshore wind farm will be capable of generating up to 2.852 GW of green energy, enough to meet the average daily needs of over 3 million UK homes. The contract was awarded following the Hornsea 3 wind farm developer Ørsted being allocated a Contract for Difference on July 7, 2022. Heerema previously completed the installation of Ørsted’s Hornsea 2 offshore substations in 2021.

The work will include transporting and installing the two OCS jackets, eight skirt piles, and the two OCS topsides. Heerema will perform offshore lifting of the jackets onto the seabed before installing the piles to ensure fixation to the seabed. After executing the jacket installation, the OCS will be completed by installing the topsides onto the jackets.

Heerema’s Chief Commercial Officer, Jeroen van Oosten: ‘We are very pleased to be awarded this contract by Aibel for the Hornsea 3 project. We have established a good working relationship throughout various successful projects together, which we will now extend to the transport and installation of these two substations.’

Hornsea 3

Hornsea 3 will be located in the North Sea, approximately 120 km off the Norfolk coast and 160 km off the Yorkshire coast. The project will include up to 231 offshore wind turbines and will be capable of generating up to 2.852 GW of green electricity.
