In early December 2017, members of the ACT Acorn Project Team braved the elements and visited the North Sea Midstream Partners (NSMP) facility at the St Fergus Gas Terminal in north east Scotland, north of Aberdeen. Natural gas from the North Sea is brought onshore at the terminal, which consists of three gas receiving plants that process and pass the gas onto a fourth facility, National Grid Gas, connected to the National Transmission System (NTS).
Up to half the gas used in the UK currently flows through the St Fergus gas terminal. Its receiving plants, operated by Ancala, Shell and NSMP, are responsible for the gas processing and sweetening operations to ensure the correct methane content and composition prior to compression and injection into the transmission system.
Despite being battered by the atrocious weather afforded by Storm Caroline, the team were warmly hosted by NSMP and px, who operate the NSMP facility. Respective presentations were followed by a site tour in full personal protective equipment.
During the tour, the team were able to see the main emission points at both the NSMP and adjacent Shell facilities, get a good understanding of the geographical layout of the facilities with respect to CO2 capture options and visit the capped end of the preserved Miller Gas System (MGS) offshore pipeline.
The terminals import gas from a wide variety of North Sea gas fields and have pipeline links to the West of Shetland and Norway. In addition to the pipelines currently in use, there are three offshore pipelines which are no longer in use: Atlantic, Goldeneye and MGS. One or more of these pipelines provides opportunity for re-use for CO2 transport. St Fergus is the third largest CO2 emissions location in Scotland, after Grangemouth and Mossmoran.
The ACT Acorn Project Team wish to take this opportunity to again thank NSMP and px for their excellent hospitality.
