摘　　要：针对No 96和Mark Ⅲ两种薄膜型LNG船的屏壁非常薄,承受压力的范围有限的问题,为保证货舱安全,比较分析这两种船型的货物围护系统、货舱和主次绝热层正常压力范围,以及引起压力过高和过低的原因,介绍货舱压力升高、降低可能触发的报警,总结薄膜型LNG船货物操作过程中应注意的问题。Considering the pressure of cargo tanks of membrane type LNG carrier including No 96 and Mark Ⅲ can bear is limited due to their very thin barriers,in order to protect cargo tanks,cargo containment systems of the two types of LNG carriers are interpreted,as well as the routine working pressure range of cargo tanks and insulation spaces of these two membrane types LNG carrier. The reasons of over pressure and under pressure are also presented. The alarms may be activated due to high or low pressure of cargo tanks are specified,and the precautions to be paid during cargo operations for LNG carrier are summarized.
