The gas is landed at three terminals at Westfield Point in Barrow-in-Furness, collectively referred to as the Rampside Gas Terminal. The South Morecambe Central Processing Complex is connected via a 36-inch pipeline to the South Morecambe terminal. North Morecambe gas has a different composition so the unmanned Drilling and Production Platform is linked by a separate 36" wet sealine to the North Morecambe Terminal, where it is stripped of water, CO2 and nitrogen. The Rivers Terminal has a dedicated pipeline for sour gas from the Calder field, which must be stripped of hydrogen sulphide before processing by the North Morecambe Terminal. The hydrogen sulphide is converted to sulphuric acid which is sold for industrial use. In 1991 a 229 MW CCGT power plant was opened near the terminals, on the site of the former coal-fired Roosecote Power Station. There is a support base at Heysham Port and personnel are typically moved by helicopter from Blackpool International Airport. Five rig workers and the two pilots of a Eurocopter AS365 Dauphin were lost when it crashed in sight of the platform on 27 December 2006.
