OSS Zingst & Darß
50Hertz
Baltic Sea, Germany
Through the HSI joint venture, Smulders HSM and Iv were responsible for the full EPCIC scope of the Zingst and Darß offshore substations.
We constructed the topside and jacket for OSS Darß at our site in Vlissingen: works on the topside began in March 2024, those on the jacket in the spring of 2025. In the autumn of 2026, we delivered both structures safely and successfully.
The construction of OSS Zingst took place at our yard in Schiedam. We began work on the topside in May 2024 and on the jacket in early 2025. Like OSS Darß, Zingst was ready for transport to its offshore installation site by the end of 2026.
In October 2026, Allseas successfully installed both jackets and topsides during a single offshore campaign.
OSS Zingst and Darß are located approximately 15 km off the German coast near Darß. The two wind farms form part of 50Hertz’s OST-6-1 grid connection. This will transmit the electricity generated by the 927 MW Gennaker offshore wind farm to 50Hertz’s onshore transmission grid.
