For the two substation topsides for the Neart na Gaoithe offshore wind farm in Scotland, GE Renewable Energy’s Grid Solutions selected HSM Offshore and Iv-Offshore & Energy in January 2020.

GE Grid Solutions is in charge of the design, supply, construction, and commissioning of onshore and offshore wind substations for the 450 MW wind farm. In a consortium arrangement, HSM will provide offshore topside platforms designed by Iv-Offshore & Energy, which will house GE’s 220 kV and 66 kV substations.

Neart na Gaoithe, developed by EDF Renewables and located some 19 kilometres off the Fife coast, entered the offshore construction phase in August 2020.
