| 摘要 |
The present invention relates to a floating storage device and, more specifically, to a floating storage device including: a liquefaction device liquefying natural gas (NG) in a gas state to liquefied natural gas (LNG); a high pressure storage tank in which LNG of a high pressure is transferred from the LNG liquefaction device and is stored; and a low pressure storage tank in which LNG except for LNG transferred from the LNG liquefaction device to the high pressure storage tank is transferred and stored. According to the present invention, the floating storage device stores LNG of the high pressure, which is liquefied in the liquefaction device, in the high pressure storage tank and the low pressure storage tank by separating LNG of the high pressure. Therefore, LNG stored in the low pressure storage tank is supplied to an LNG without additional pressure control process or facility thereof when LNG is supplied to the other vessel, and LNG stored in the high pressure storage tank can be supplied to an LNG fuel vessel. |
