The North Morecambe Area Development is located in the Irish Sea approximately 38 km South-West of Barrow. It consists of three separate fields with estimated recoverable reserves of 1 Tcf. Utilization of North Morecambe gas required a wide range of processes due to significant quantities of carbon dioxide and nitrogen. The overall philosophy on the North Morecambe project was to minimize plant and processing facilities offshore such that the platform could be considered ’not normally manned’. In order to locate the majority of equipment onshore, a wet sea line was required with methanol acting both as a hydrate inhibitor and as a carrier for a corrosion inhibitor. To meet National Transmission specifications, the gas required the removal of all the carbon dioxide, some of the nitrogen as well as the more conventional conditioning requirements of separation, condensate stabilization and sweetening, hydrocarbon and water dewpoint control, compression and methanol recovery, making it the most complex gas processing terminal in Europe. The paper will review the overall process route, the choice of processing facilities, taking into account declining field pressures/flows and the development of new satellite fields with varying gas compositions feeding the terminal, as well as the commissioning of the plant in 1994 and its current operability.
