The Bacton Gas Terminal is a large gas terminal found on the North Sea coast in North Norfolk near Paston and between Bacton and Mundesley. The nearest main town is North Walsham. The other main UK gas terminals are at St Fergus, Aberdeenshire and the Easington, East Riding of Yorkshire.

The plant opened during 1968, initially built by Shell and the Gas Council. Planning permission had been given on 16 June 1967 by Anthony Greenwood, Baron Greenwood of Rossendale. The Leman field began on 13 August 1968 (joint Shell-Esso), and the Hewett field (Phillips Petroleum) began operations in July 1969. Construction of the £5 million Phillips plant began in April 1968. The Leman field (Shell-Esso) needed a 34-mile-long pipeline. A 36-inch diameter 140-mile-long pipe (Number 2 feeder main) costing £17 million was built by Italsider from Bacton to near Rugby. The Gas Council marketed the new North Sea gas as High Speed Gas.
On 13 August 1981, 11 gas workers lost their lives in the G-ASWI North Sea ditching, in a Wessex helicopter. At 6pm on 28 February 2008, there was an explosion and fire at the Shell UK terminal, for which Shell were fined £1 million.
It consists of five gas terminals, taking gas from the Southern North Sea (SNS). From there, they connect to the National Transmission System or to Belgium via the Interconnector and to the Netherlands via the BBL Pipeline. The gas terminals are run by Royal Dutch Shell, ExxonMobil, Perenco (which took over the BP operations in September 2003) and ENI (which took over the Tullow Oil operations in December 2008). Tullow had begun operations in 2003.
The five terminals are
- National Grid - The National Transmission System (NTS)
Initial gas processing takes place on the gas rigs, where the gas is received with a slugcatcher, dehydrated using triethylene glycol then compressed. Sour gas (sulphurous) had previously been removed by amine gas treating, but not presently. Gas enters the NTS at around 1000 psig. Condensate is removed and piped by the British Pipeline Agency to the North Walsham rail terminal.
The Shell terminal takes gas from the 474 kilometres (295 mi) long SEAL Pipeline, which connects to the Shearwater and Elgin-Franklin gas fields in the Central North Sea. The SEAL Pipeline is the longest on the UK Continental Shelf. It employs 46 people and began operations in 1968. It connects to the BBL Pipeline to the Netherlands which became operational in December 2006.
Hewett Bacton Terminal
This takes gas through seven pipelines from the Leman, Indefatigable, Trent & Tyne, Thames, Hewett & Lancelot Area Pipeline System (LAPS) and its Arthurian fields.
The ENI terminal was integrated in to the Perenco Terminal in 2011, thereby diverting the Hewett, LAPS and Thames pipeline gas and liquids via the Perenco Terminal. The remaining and now unused facilities on the ENI terminal are at this time (April 2014) being demolished.
The Eni-operated terminal takes two pipelines from the Hewett complex, one from the Thames complex and one from the Lancelot (LAPS) complex. Each set of pipelines are received and processed separately.
