General – EPCIC Contract
The HSI joint venture, comprising HSM Offshore Energy, Smulders, and Iv, has safely rolled out the topside of OSS Zingst at HSM Offshore Energy’s yard in Schiedam, the Netherlands.
This is the next step in delivering Germany’s newest and most powerful offshore wind infrastructure for transmission system operator, 50Hertz.
OSS Zingst is one of two offshore substations, together with OSS Darß, forming the OST-6-1 grid connection in the German Baltic Sea. With a combined transmission capacity of 927 MW, OST-6-1 will connect the Gennaker offshore wind farm, which will be Germany’s largest upon completion, to the onshore grid.
The topside of OSS Zingst is an impressive structure, measuring 48 × 33 × 17.5 m (L × W × H) and weighing 4700 metric t. Once installed offshore, the offshore substation will collect and transform the 450 MW of power generated by the Gennaker wind farm before transmitting it to the onshore grid.
Under the EPCIC contract, the HSI-consortium is responsible for the engineering, procurement, construction, installation, and commissioning of the Ostwind3, Zingst, and Darß topsides and their jackets.
The joint venture’s integrated approach enables efficient coordination, consistent technical consistency, and the highest safety and quality standards, which are essential for delivering a project of this scale.
