Jack-up Thialf has successfully placed the topside for TenneT’s offshore wind transformer platform Hollandse Kust west alpha on the jacket.
This new milestone for the offshore wind connection took place last night about 50km off the coast of Egmond aan Zee, TenneT said.
From 2026 TenneT aims bring sustainable wind energy onshore via this “offshore socket”.
The ready-made topside left the Port of Antwerp on a floating pontoon on Monday.
The structure was then towed via the Scheldt to Dutch waters to enter the North Sea at Vlissingen.
The topside was built in Belgium by the contractor combination Equans/Smulders and almost two years after the first steel cut, the large steel box weighing over 3600 tonnes was ready for the sail out this week.
For the installation of the superstructure, the Heerema Marine Contractors vessel Thialf set sail for the jacket from the Norwegian port of Stavanger at the same time as the topside.
After both vessels met at sea, the pontoon moored against the Thialf.
