The HSI joint venture, comprising HSM Offshore Energy, Smulders and Iv, has completed the rollout of the OSS Zingst offshore substation topside at HSM Offshore Energy’s yard in Schiedam, the Netherlands. OSS Zingst is one of two offshore substations, together with OSS Darß, that form the OST-6-1 grid connection in the German Baltic Sea and will connect the Gennaker Offshore Wind Farm.
The OSS Zingst topside measures 48 × 33 × 17.5 metres and weighs around 4,700 tonnes. Once installed offshore, the substation will collect and transform up to 450 MW of electricity generated by the Gennaker Offshore 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, as well as their jackets.
Located in the German Baltic Sea, the OST-6-1 offshore grid connection has a total transmission capacity of 927 MW. The two substations, Zingst and Darß, will connect the Gennaker Offshore Wind Farm to the 50Hertz transmission grid, supporting grid capacity in northern Germany.
