摘　　要：基于某多功能海上重吊船液化天然气(Liquefied Natural Gas,LNG)双燃料系统的设计,结合其典型运营工况,采用经济性(Economic Performance,EP)分析方法对LNG燃料和低硫船用轻质柴油(Low Sulfur Marine Gas Oil,LSMGO)燃料的能量消耗、额外初始投入成本、运营成本(Operating Expense,OPEX)等进行分析比较。结果表明,在满足设计要求的前提下,在中长期的船舶运维周期内,LNG燃料的EP更好。考虑未来船用清洁燃料的发展,相关研究可为海上工程作业船舶的燃料动力系统的设计和选择提供思路。Based on the design of Liquefied Natural Gas(LNG)dual-fuel system of a multi-purpose marine heavy lift vessel and combined with its typical operating conditions,the energy consumption,extra initial cost,and Operating Expense(OPEX)of LNG fuel and Low Sulfur Marine Gas Oil(LSMGO)fuel are analyzed and compared with the Economic Performance(EP)analytical method.The results show that under the premise of meeting the design requirements,EP of LNG fuel is better in the medium and long term of ship operation and maintenance cycle.In view of the development of marine clean fuel in the future,the relevant research can provide ideas for the design and selection of fuel power system for marine engineering vessels.
