<P>PROBLEM TO BE SOLVED: To minimize a generation risk of roll over, when a plurality of kinds of LNG different in density are stored in one and same LNG tank. <P>SOLUTION: The LNG receiving structure employed includes a lead pipe that is set below a receiving pipe penetrating through the roof of an LNG tank and extends to the bottom of the LNG tank; a hopper that is set at the upper end of the lead pipe and receives the LNG ejected from the receiving pipe; a gas-liquid separation structure that is arranged in the lead pipe so that the LNG ejected from the receiving pipe drops through the center of the lead pipe while reducing its speed and the gas separated from the LNG rises upward along the inner wall of the lead pipe; and a gas discharge port that is formed in the hopper and discharges, outside the hopper, the gas rising upward from the lead pipe. <P>COPYRIGHT: (C)2012,JPO&INPIT |
