Abstract: The plan for tank configuration in LNG terminal's design is of significance. The number and capacity of LNG tank not only restricts the terminal scale in receiving, storing and gasifying, but also affects the investment and the economy of LNG terminals. Definitions of capacity, calculation method and influencing factors of LNG terminal are described. And the influence of LNG shipping program, differential gas supply and storage period on tank configuration program of LNG tank in receiving terminals are analyzed with actual cases.
