The cable deck, weighing 842 tonnes, was manufactured in two parts at Smulders’ Hoboken yard in Belgium and then joined and fully outfitted in Vlissingen, the Netherlands.
With the jacket now structurally complete, Smulders will focus on final preparations for the load-out scheduled for later this year. The jacket features four fully equipped rooms, including locker rooms and technical spaces.
The project is being executed on behalf of 50Hertz by the HSI consortium, comprising HSM Offshore Energy, Iv, and Smulders. The consortium is responsible for the full engineering, procurement, construction, installation, and commissioning (EPCIC) scope of the Jasmund offshore substation topside and associated jacket.
The topside was rolled out at the HSM Offshore Energy yard in Stormpolder, the Netherlands, in March 2025. The unit weighs 5,300 tonnes, and its dimensions are 68x37x21 metres.
Once operational, the Jasmund substation will serve as a connection point between the Windanker offshore wind farm, located northeast of the island of Rügen in the Baltic Sea, and the electricity grid.
The substation is planned to have a capacity of 300 MW, supplying enough renewable energy to power about 260,000 households.
