摘　　要：文章通过对国际和国内碳排放政策的研究,分析了甲醇改装在环境和成本上的优势,以15万DWT穿梭油船为例,叙述了以甲醇为主的双燃料系统改装设计。对甲醇舱、日用柜布置及方案选型,以及主要设备改装等进行研讨,对改装注意事项进行了较详细的叙述,并计算改装前后的船舶能耗指数(EEXI)。对比结果表明:改装后该船的EEXI有较大的提升,绿色性能显著,可为同类型船舶清洁燃料设计研发提供参考。Based on the research of international and domestic carbon emission policies,this paper analyzes the advantages of methanol conversion in terms of environment and cost,and takes a 150000 DWT shuttle tanker as an example to describe the design of the methanol-based dual-fuel system.This paper discusses the layout and scheme selection for the methanol tank,daily tank and the main equipment modification.It details the points for attention in modification,and calculates the energy efficiency existing ship index(EEXI)before and after modification.The comparison results show that the EEXI of the ship after modification indicates great improvement and remarkable green performance,which can provide a reference for the design and development of clean fuel for the same type of ship.
