Yesterday, the load-out of the first of two offshore substation (OSS) topsides for the 450 MW Scottish Neart na Gaoithe offshore wind farm took place at HSM Offshore’s yard in Schiedam.
The Neart na Gaoithe offshore wind farm is being built 15.5 km off the Fife coast in Scotland by a consortium of EDF Renewables UK and ESB. The wind farm will feature 54 Siemens Gamesa Renewable Energy 8 MW wind turbines. Two offshore substations will collect and transform the electricity produced by these wind turbines.
A consortium of GE Renewable Energy’s Grid Solutions business, HSM Offshore and IV-One was commissioned to deliver both the two offshore substations and the onshore station for Neart na Gaoithe. The scope of work includes the design, supply, construction and commissioning of the substations. GE is responsible for the turnkey delivery of all infrastructure within the perimeter, including ground works and civil construction.
HSM Offshore delivers the offshore topsides, designed by Iv-Offshore & Engineering, that will house GE’s 220kV and 66kV substations. Each topside measures 35 x 25.5 x 15 metres, weighs 1200 tonnes and has a capacity of 225 MW. A single HV transformer transforms the electricity from 66 kV to 220 kV.
Offshore construction in the wind farm started in August 2020. The wind farm is expected to be fully operational in 2023, generating enough electricity to provide green power to around 375,000 households. Source: HSM Offshore Image: Iv-Offshore & Engineering
