The HSI joint venture has rolled out the Zingst offshore substation topside at HSM Offshore Energy’s yard in Schiedam for transmission system operator 50Hertz.
The partners, a consortium of HSM Offshore Energy, Smulders and Iv, said the structure is part of the OST-6-1 grid connection in the German Baltic Sea, which will link the Gennaker offshore wind farm to the onshore grid via the Zingst and Darß substations.
The topside measures 48×33×17.5 metres and weighs 4700 tonnes, while the roll-out marks progress ahead of load-out, sail-away and installation.
Under the EPCIC contract, the consortium is delivering the Ostwind3, Zingst and Darß topsides and jackets.
Hans Leerdam, chief commercial officer of HSM Offshore Energy, said: “Rolling out the Zingst topside underscores the strength of our consortium and our shared commitment to supporting Europe’s offshore wind expansion.”
“This milestone highlights the dedication and technical excellence of our teams across all partners. Zingst represents not only impressive engineering, but also a meaningful contribution to Europe’s sustainable energy ambitions,” said Wim Vaes, commercial director Smulders.
Fedor van Veen, managing director offshore & energy at Iv, stated: “We are pleased to see the Zingst platform reach this important phase. It shows how months of engineering have resulted in a buildable platform.”
