Mammoet has signed an agreement with Seatrium to carry out the load-out of three substations for TenneT’s 2GW offshore grid connection programme.
The work sits within a wider plan to install 15 HVDC grid connection systems in the North Sea by 2032—eight in the Netherlands and seven in Germany—each rated at 2GW.
Under Seatrium’s One Seatrium Global Delivery model, topside fabrication will be carried out across its key yards. Each topside is expected to weigh more than 30,000 tonnes.
Mammoet will manage the movements and load-out using specialist skidding equipment to transfer each structure between land and sea-going transport vessels. The company said its hydraulically compensated skidding systems are intended to support accurate positioning during transfer and reduce structural deflection.
The partners added that deploying higher-capacity systems offshore is expected to support Dutch, German and wider European climate targets while reducing the number of offshore facilities required.
Richard Verhoeff, global sales director at Mammoet, said the company is proud to partner with Seatrium on the programme and will apply engineered solutions to load the structures onto transport vessels in a controlled manner.
