Abstract: Natural gas carriers are the mainstream green ships built in recent years, with significant increase in demand. In this paper, to solve the problem of rather slowly filling into Type C storage tank at present, we have invented a new method and practiced to precool the tank quickly through analysis of the precooling process and time, so as to obtain a method for filling temperature. In comparison with the precooling process currently in use, it has the effect of short filling time and low cost, which is successfully used in a LPG carrier.
Key words: type C tank filling; precooling way; LNG filling
