Abstract
British Gas has 20 above-ground LNG tanks in service, representing some 250 tank-years of experience. No major incidents have occurred with any of these tanks. Operational problems have been experienced with tanks, bunds, LNG valves and pumps; these have all been overcome without recourse to warming up or decommissioning the tanks. This paper summarizes British Gas's operational experiences, describing, in particular, how problems have been overcome. One above-ground tank has been decommissioned recently, for operational rather than technical reasons. This provided an excellent opportunity for detailed study of the condition of an LNG tank after 14 years of operational service. In addition mention is made of the (now decommissioned) in-ground LNG storage tanks, formerly used by British Gas.
