Aibel has contracted Heerema Marine Contractors to transport and install two Offshore Converter Stations (OCS) for the Hornsea 3 offshore wind farm.

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 said: "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."


The company is expected to take final investment decision on
Hornsea 3 within 18 months and potentially as soon as by end of 2022.

The UK Department for Business, Energy and Industrial Strategy (BEIS) recently awarded Ørsted a contract for difference for
Hornsea 3. The project, being developed by Ørsted, was awarded at an inflation-indexed strike price of €37.35/MWh in 2012 prices.

With a capacity of 2,852 MW,
Hornsea 3 is expected to produce enough electricity to power 3.2 million UK homes. Ørsted is expected to take final investment decision on Hornsea 3 within 18 months and potentially as soon as by end of 2022. When the wind farm has been fully commissioned, Ørsted will, in accordance with UK regulation, divest the transmission assets to a new owner.
