FUEL GAS SUPPLY SYSTEM AND AN LNG CARRIER WITH THE SAME TO SELECTIVELY RE-LIQUEFY EVAPORATED GAS SUPPLIED TO A DOUBLE FUEL ENGINE

摘要

PURPOSE: A fuel gas supply system and an LNG carrier with the same are provided to reduce the amount of evaporated gas unnecessarily consumed.;CONSTITUTION: A fuel gas supply system comprises a compressor(30), a supply pipe(42), a branch pipe(44), a heat exchanger(110), and a cooling unit(120). The compressor compresses the gas evaporated from an LNG storage tank. The supply pipe supplies the compressed evaporated gas to a double fuel engine. The branch pipe is branched from the supply pipe and selectively provided with the evaporated gas. The heat exchanger re-liquefies the evaporated gas passing through the branch pipe. The cooling unit provides cooling heat for cooling the evaporated gas to the heat exchanger.;COPYRIGHT KIPO 2011
