PURPOSE: A ship is provided to prevent the level of LNG stored in a storage tank from lowering below the operational water level of a pump by returning reliquefied boil-off gas to a storage tank. CONSTITUTION: A ship comprises a hull, a storage tank(10), a first path(210), a cooling unit, a second path(220), a pump, a third path(230), a reliquefying device, and a fourth path. The storage tank is installed on a hull to store LNG. The first path guides boil-off gas generated in the storage tank to an engine. The cooling unit is placed in the first path, and cools the boil-off gas. The second path supplies the LNG stored in the storage tank to the cooling unit. The pump is connected to the second path and pumps the LNG. The third path is branched from the first path, and is connected to the storage tank. The reliquefying device is installed on the third path in order to reliquefy the boil-off gas. The fourth path connects the third path with the second path, and is connected to the rear end of the reliquefying device. [Reference numerals] (250) Reliquefying device; (AA) DF engine |
