The Shetland Gas Plant is a natural-gas processing plant in the Shetland Islands, Scotland.
History The Shetland Gas Plant is the collection and gas processing facility for the offshore Laggan-Tormore project, comprising two large gas and gas condensate fields. The Laggan gas field was discovered in 1986. The Tormore condensate field was discovered in 2007. The development plan for the site was approved in March 2010.
The site was formally opened by Amber Rudd, the Secretary of State for Energy and Climate Change, on 16 May 2016.Shetland Times
Structure The plant is connected to the Shetland Islands Regional Gas Export Pipeline (SIRGE). The plant was built by Petrofac's Offshore Engineering & Operations unit; Petrofac is a recent constituent of the FTSE 100 Index.Petrofac The site and pipelines cost around £800m. The gas is exported from the site via a diameter pipe south to the Frigg UK System in Aberdeenshire.
The site is adjacent, to the east, of the Sullom Voe Terminal.
Operation The Laggan and Tormore gas fields are around north-west of the Shetland Islands, in sea depths of . Production from the plant began on 8 February 2016. The production from the Laggan-Tormore project is expected to be around 93,000 barrels of oil equivalent per day.
