The St. Fergus Gas Plant
in St. Fergus
, is a set of four gas processing plants
The plant was initially developed by British Gas and Shell. The three main plants have three main pipelines each coming ashore. The Centrica plant receives gas from the other main three plants. In total, St Fergus receives around 35% of the UK's gas.
The Total part of the refinery opened in September 1977 for the Frigg pipeline, with another section opening in 1978 for the Vesterled
pipeline. The Queen
opened this plant officially on May 9 1978.
The Shell plant opened in April 1982, being officially opened by Prince Charles
in October 1982, taking gas from the Brent
field, via the FLAGS
pipeline. Gas came from the Fulmar
field in July 1987, via the Fulmar Gas Pipeline
, and from the Goldeneye field
in October 2004. It employs around 180 people.
This plant uses the SAGE pipeline from the Brae
The purpose of the receiving plants are to clean the delivered gas and present the Methane
content to the adjacent British Gas
has a capacity of around 22.8 Mm SCM
for the FLAGS line and 2.8 Mm SCM/d for the Fulmar Gas Line. It produces 18.19 Mm scu m/d of gas to the British Gas plant and exports 8,000 tonnes of liquid products to Mossmorran
This plant receives gas from twenty gas fields (including Alwyn, Miller, Bruce and most recently Rhum
) and produces 20% of the UK's gas needs. Until 1987, gas only came from the Frigg field, and production from this field finished in October 2004. Gas is transported to the TOTAL plant by the Frigg pipeline
There is also an adjacent plant operated by ExxonMobil.
and heavier products are separated and sent onward to a further plants located at Mossmorran
(owned by Shell) and Cruden Bay
(owned by BP). Separation is by a cryogenic
For the Fulmar Gas pipeline, a gas de-sulphurisation plant is used to remove hydrogen sulphide and reduce the water content.
