Heerema Fabrication Group fabricated the offshore substation for the Galloper project, which forms part of the Galloper OFTO transmission assets. At its Hartlepool yard in the UK, Heerema built the substation topside and the associated jacket foundation before loading them onto transport barges for delivery to the offshore site in the Outer Thames Estuary. These structures house the 33/132 kV equipment that collects and transforms power from the Galloper turbines for transmission to shore and were later transferred as part of the OFTO sale to Diamond Transmission Partners. Lifecycle stage: construction.
