Compared with 1975 data, the economics and technology of today's baseload liquefaction plants call for sharply higher capital costs due to worldwide inflation and design changes. Two major trends are evident in process design: increased liquefaction train capacity reduces the capital investment while more efficient refrigeration and power generation cycles cut plant fuel consumption. Safety devices in storage tank design have had the biggest economic impact. Both the double integrity and spherical tank designs increased installed storage costs by 100% or more over the cost of older single-containment, double-wall tanks. Other safety and design features, such as full hydrostatic testing of the inner tank and the use of intank pumps, further added to the installed tank cost. New concepts in plant design philosophy involve floating and bargemounted plants as a means of reducing costs associated with field construction in remote and hostile environments. Coupling the updated cost data with new information for LNG shipping permits rapid estimation of total facility costs (liquefaction, shipping, and regasification) for an entire baseload LNG project.
