摘要： 计算非装载状态下液化天然气（LNG）闪蒸气（BOG）,根据BOG气相出口阀门开度、装载LNG温度、组分维度,利用HYSYS软件对BOG产生量进行对比,得出在不同边界条件下的舱压、温度变化规律,并根据该规律提出设备配置及运营建议。

Abstract: The boil-off gas （BOG） of LNG in an unloaded state is calculated. Based on the opening of the BOG gas-phase outlet valve,LNG loading temperature,and component dimensions,the BOG production is compared by using HYSYS software,and the variation rules of cabin pressure and temperature under different boundary conditions are obtained. According to the rules,suggestions for equipment configuration and operation are proposed.

Key words: FSRU, BOG calculation, BOG dynamic simulation, LNG loading
