Haven's facilities were configured for crude oil production from multiple wells tied into the platform's steel jacket structure, with primary separation and metering for export. The platform exported stabilized crude via subsea pipeline networks to onshore terminals, and produced associated gas was either flared or exported according to field connections at the time. Utilities included platform power generation systems, fire and safety systems, and accommodations for personnel when operational. In its decommissioning phase, wells are being plugged, topsides and jackets removed, and seabed restoration undertaken per regulatory requirements. The design reflected typical 1980s North Sea oil production platforms with robust processing and export capabilities tailored to the shallow Block Q reservoirs.
