BOIL-OFF GAS COOLING SYSTEM AND METHOD OF LNG CARRIER

摘要

An evaporative gas cooling system and a method of a LNG carrier is provided to prevent the heat penetration and to make the cooling and reliquefaction structure of the evaporative gas simple. An evaporative gas cooling system of a LNG carrier comprises a marine propeller, a thermo-electric cooler(2) and a transformation of electric energy part(12). The marine propeller is a dual fuel combustion engine(10) having a generator(11). The thermo-electric cooler performs cooling by utilizing electrical characteristic of two kind metals. The thermo-electric cooler is electrically connected to the generator of the dual fuel combustion engine with an electric supply line(L11). The transformation of electric energy part is connected to the supply line.
