The Grane platform is a large steel jacket installation with integrated topsides housing drilling facilities, multiphase separators, and utility systems. It supports up to ~40 well slots for production and injection wells, with horizontal drilling programs to optimise recovery. Hydrocarbons from production wells undergo primary separation topside: crude oil is stabilised and metered before export via a dedicated pipeline to the Sture onshore terminal, where storage and further transport to markets occur. Associated gas is reintroduced into reservoir zones via gas injection for pressure maintenance, with import gas lines from nearby Heimdal enhancing injection capacity. Utility systems on the Grane platform include power generation (gas turbines), water treatment, produced water handling, gas compression for reinjection and lift, living quarters with safety systems, and integrated control and safety shutdown infrastructure. The fixed platform connects to subsea flowlines and control umbilicals, and its design accommodates harsh North Sea environmental loads, redundancy for critical processing trains, and comprehensive fire and gas detection systems typical of long-life offshore production hubs.
