Abstract
A system is provided for disposal of gaseous hydrocarbons produced from an undersea well, which minimizes the gas disposal cost. The system includes a polymerization station (80) mounted on an anchored floating vessel arrangement (12), which converts the gas to a liquid hydrocarbon that is stored and then transported by a shuttle tanker (52) to a refinery. The liquified gas can be mixed with liquid hydrocarbons originally obtained from the undersea well, both in the shuttle tanker and in storage tanks on the anchored vessel arrangement. Sea water can be used to create steam for the polymerization process.
