Offshore LNG (liquefied natural gas) production and storage systems
A barge, outfitted with gas liquefaction processing equipment and liquefied natural gas (LNG) storage tanks, is suggested as a possible way to exploit remote offshore gas production. A similar study with a barge-mounted methanol plant was conducted several years ago, also using remote offshore feed gas. This barge-mounted, LNG system is bow-moored to a single point mooring through which feed gas is piped via seafloor pipeline from a nearby gas production facility. The barge is arranged with personnel accommodation forward, LNG storage midships, and gas liquefaction processing equipment aft. A flare boom is cantilevered off the barge's stern. The basis of design stipulates feed gas properties, area environmental data, gas liquefaction process, LNG storage tank type plus other parameters desirable in a floating process plant. The latter were concerned with safety, low maintenance characteristics, and the fact that the process barge also would serve as an offshore port where LNG export tankers would moor periodically. A brief summary of results for a barge-mounted methanol plant from an earlier study is followed then by a comparison of LNG and methanol alternatives.
