摘　　要：针对船舶主机COx排放量需满足国际海事组织(IMO)的要求,文章基于甲醇燃料动力系统展开设计和布置分析。具体针对加注系统和惰化监测功能等关键问题方案进行研究,结果显示:采用U型包围式顶平设计可节省主甲板空间和实现自流通断功能。分析表明,在燃料舱上设计PV阀并在其出口管路上设置干燥气吹扫(风速0.5~3.0 m/s)和可燃气体探测,可有效进行燃料舱压控制和惰化监测,并增强了系统的安全性。The COx emissions of ship main engines should meet the relevant requirements of IMO.This paper conducts design and layout analysis based on methanol fuel power systems,and meanwhile studies specifically key issues such as the bunkering system and inerting monitoring function.The results show that the utilization of the Utyped enclosed top flat design can save space on the main deck and achieve self-flow on/off function.The analysis shows that PV valves set on the fuel tank,and dry gas purging(wind speed of 0.5~3.0 m/s)and combustible gas detec⁃tion installed on the valve outlet can effectively control fuel tank pressure and conduct inerting monitoring,with en⁃hanced system safety.
