Theddlethorpe Gas Terminal (TGT) is a large gas terminal on the Lincolnshire coast on Mablethorpe Road at Theddlethorpe St Helen close to Mablethorpe in East Lindsey in England. It is just off the A1031 and next door to a holiday camp and Mablethorpe Seal Sanctuary (Animal Gardens).

History

From December 1969, there were plans for the terminal proposed by the Gas Council. Planning permission was given in April 1970. It was built in 1972 to receive gas from the Viking gas field from 4 July 1972, being the UK's third main gas terminal when owned by Conoco. The first stage cost around £5 million. A new 86-mile (138 km) 28-inch (710 mm) offshore gas pipeline had to be built for the plant. It was originally called the Viking Gas Terminal, changing to its current name in 1984.

In the early 1990s, a new pipeline was built to the terminal by Kinetica, a company jointly owned by PowerGen and Conoco. The pipeline to Killingholme was opened by Tim Eggar on 21 July 1992.

Operation

The main site is owned by ConocoPhillips, with pipelines to National Grid's National Transmission System, and E.ON's 20-inch (510 mm) Killingholme Pipeline System[1] to both Killingholme A power station and Killingholme B power station, transporting 256,000 m3/h at a pressure of 40-55 bar. 10% of the UK's ever increasing gas requirements come from Theddlethorpe. Around one hundred people work on the site.

Offshore pipeline systems

These are in the areas known as the UK Southern Gas Basin or Southern North Sea Basin. This is part of the UK Continental Shelf (UKCS).

Natural gas liquids

Any liquids from the refinery operation get transferred to Phillips 66's (previously ConocoPhillip's when the two companies were one) Humber Refinery next door to the Killingholme Power Station (ICHP), twenty six miles away to the north-west of Theddlethorpe.

Gas fields

Viking

The main field that connects to the terminal is the Viking gas field, via the Viking Transportation System. It is 86 miles (138 km) off the Lincolnshire coast, and is in two sections - Viking A and Viking B. It is 50% owned by ConocoPhillips. Production on the North Viking Field began in July 1972 and South Viking in August 1973 after the North Viking field was discovered in March 1969 and South Viking in December 1968. It was initially operated by Conoco and the National Coal Board, then by ConocoPhillips on behalf of BP (former Britoil), and was jointly owned by both. It is close to the Indefatigable field, and a plan was to use the (nearer) Bacton gas plant instead. Production from the Viking gas field was the main incentive to build the Theddlethorpe site.
