Abstract
At present, the annual output of the offshore natural gas in the world is 4500×108m3accounting 21% of the total annual output of the natural gas in the world. For the exploitation of offshore natural gas, not only the stern environ ment, complex technique and tremendous investment will be confronted with but also the cycle is long, the cash recovery slow and the risk relatively great. Up to now, the devdoped gas fidds are all large-sized commercial ones, while a large number of marginal offshore gas fields are generally medim- and small sized ones. If these gas fidds are developed by use of the com mon fixed platform, the profits will be relatively low and risk great,having no sufficient appeal to the investors. The floating production, storage and off-loading is a new technique for marginal gas field development,having the advantages of few in vestment,short construction cycle and repeatable utilization. In this paper, the concept of FPSO is presented and the technologi cal process of the liquefaction, storage and off-lond systeans of LNG and the overall arrangement of FPSO are explained.关键词
