Seaway Heavy Lifting Contracting Limited was appointed by the Westermost Rough developer to install the offshore substation platform for the Westermost Rough transmission assets. Using its heavy‑lift vessel, Seaway Heavy Lifting transported and lifted the STX‑built topside onto the pre‑installed jacket foundation within the wind farm area. The company’s scope covered offshore transport, lifting, positioning and installation of the HVAC offshore substation, which subsequently became part of the regulated Westermost Rough OFTO transmission system.
