CS WIND, previously known as Bladt Industries, partnered with Semco Maritime to design and build the three offshore substations for Hornsea One, which are part of the Hornsea 1 OFTO transmission assets. CS WIND contributed to the detailed engineering and fabrication of the offshore substation platforms, working alongside Semco Maritime to deliver the structural and topside scope required to collect power from the wind farm and feed it into the 220 kV export system.
