PROBLEM TO BE SOLVED: To decrease boil-off gas generated, when liquefied gas is received. SOLUTION: LNG gas is received in an LNG storage tank 11 via a funnel pipe 14 after a flow of LNG via a feed pipe 13. A float 20 is situated in the funnel pipe 14 and serves as an obstacle to a drop of LNG received from the receiving port 18 of the funnel pipe 14, and also reduce an amount of boil off gas(BOG), rolled in accompanying its drop, through the decrease of a drop speed. Since the amount of BOG rolled when LNG is received is decreased, the peak of an amount of BOG generated in the LNG storage tank 11 increased after being decreased once, when LNG is received is also decreased. Treatment capacity necessary during the peak of BOG treatment equipment connected to a BOG piping 16 is decreased, and equipment cost is also decreased.
