The Britannia field lies approximately 130 miles (210km) northeast of Aberdeen, Scotland, in the UK Central North Sea, in water depths of approximately 480 feet (146m). The Britannia field is operated by Harbour Energy (58.65%), with Ithaca Energy owning a 32.38% non-operated working interest in the field alongside NEO Energy 8.97%.
Discovered in 1975 and extending across Blocks 15/29a, 15/30a, 16/26a, 16/27a and 16/27b, Britannia was one of the largest natural gas and condensate fields in the North Sea when first production was achieved in 1998. The field includes a drilling, production and accommodation platform and a bridge linked platform at its eastern end.
Britannia condensate is delivered through the Forties Pipeline System to the oil stabilisation and processing plant, Kerse of Kinneil, near the Grangemouth Refinery in Scotland. Britannia gas is transported through a dedicated Britannia Gas Pipeline to the Scottish Area Gas Evacuation facility at St. Fergus, Scotland. The Brodgar, Callanish, Enochdhu and Finlaggan fields have been developed as satellites of the Britannia field. The Ithaca Energy operated Alder development is also a satellite of the Britannia field. Production started at Alder in November 2016.
