Seatrium and Mammoet to load out 3 TenneT 2GW substations in Europe

Netherland and Germany to host 15 HVDC connections by 2032.

Seatrium and Mammoet have entered an agreement to load out three substations for TenneT’s two-gigawatt offshore grid connection programme, connecting offshore wind farms to the European mainland, according to a press release.

The programme includes the installation of 15 high-voltage direct current grid connection systems in the North Sea by 2032. Eight systems will be located in the Netherlands, whilst seven will be in Germany, each with a capacity of two gigawatts.

Seatrium will manufacture the topsides at its shipyards, with each weighing more than 30,000 tonnes. Mammoet will be on site to execute the movement and load-out of the platforms, using specialist skidding equipment to transfer each unit between land and sea-going vessels.

The project supports climate targets in the Netherlands, Germany, and Europe. The use of higher-capacity connection systems reduces the number of offshore facilities, helping to limit environmental impact, the press release said.

“We are proud to partner with Seatrium for this innovative offshore wind programme, which will support Europe’s net-zero and energy independence ambitions. Our work is redefining the scale at which these key energy projects can be built,” said Richard Verhoeff, Global Sales Director at Mammoet.
