PURPOSE: An LNG tank vessel for using LNG to reliquefaction of boil-off gas is provided to effectively manage the operation of a facility by heat-exchanging boil-off gas returning through a boil-off gas return pipe and LNG supplied through a fuel supply pipe in real time for liquefaction.;CONSTITUTION: An LNG tank vessel for using LNG to reliquefaction of boil-off gas comprises a fuel feeding line(300), a boil-off gas line(310), a heat exchanger(400), and a compressor(500). The fuel feeding line supplies LNG from a storage tank of the LNG tank vessel to a fuel tank of a LNG propelled vessel. The boil-off gas line supplies boil-off gas from the fuel tank to the storage tank. The heat exchanger is installed through the fuel feeding line and the boil-off gas line and heat exchanges the LNG supplying from the storage tank and the boil-off gas forcibly transferred and pressurized from the fuel tank. The compressor is installed in the boil-off gas line and compresses the boil-off gas of the fuel tank to make the pressurized boil-off gas.;COPYRIGHT KIPO 2012
