Engie Fabricom, working in consortium with Iemants for DONG Energy, built and supplied two offshore HVAC substation platforms for the Walney Extension project, which later formed the Walney Extension OFTO transmission assets. The consortium fabricated the 2,900-tonne topsides and jacket foundations at Hoboken, Belgium, before transportation offshore. These substations collect and export power from the Walney Extension wind farm to shore via the OFTO link.
