摘    要：天然氣船舶是近年來的主流綠色船舶，需求量大幅增加。本文針對(duì)目前C型LNG儲(chǔ)罐加注較慢的問題，通過預(yù)冷流程和時(shí)間分析，創(chuàng)新并實(shí)踐了一種迅速預(yù)冷儲(chǔ)罐，達(dá)到加注溫度的方法，與目前常用的預(yù)冷流程對(duì)比，具有加注時(shí)間短費(fèi)用低的效果，并在某型液貨船上成功應(yīng)用。

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
