The Netherlands / Germany: The offshore substation OSS Jasmund has started its transport from the Netherlands towards the Baltic Sea, marking a key milestone for the Ostwind 3 offshore grid connection project led by German transmission system operator 50Hertz.
The HSI consortium, made up of HSM Offshore Energy, Smulders and Iv, has completed the start-up of both the OSS Jasmund topside and its jacket structure. The 4,500-t platform departed from HSM Offshore Energy’s Stormpolder yard and was carefully transported through central Rotterdam, passing under the Brienenoord and Erasmus bridges in a complex logistics operation.
At the same time, the 72-metre-high jacket structure left the Smulders shipyard in Vlissingen. Both components are now bound for the Baltic Sea, where they will be installed near the island of Rügen.
Once offshore, Heerema Marine Contractors will handle the installation works. The substation will serve as the grid connection point for the Windanker offshore wind farm, transmitting electricity from the Baltic Sea to the mainland network. With a planned capacity of 300 MW, OSS Jasmund will play an important role in strengthening northern Europe’s offshore wind infrastructure.
The project forms part of the wider Ostwind 3 programme, which also includes the future Zingst and Darß offshore platforms. Together, these assets are intended to support the growing contribution of offshore wind to Germany’s energy mix.
According to the HSI consortium, the project reflects close technical cooperation across design, fabrication and transport, with a strong focus on safety and coordination. The delivery of OSS Jasmund represents another step forward in expanding offshore grid capacity in line with Europe’s energy transition goals.
