摘　　要：为提升现有的营运船舶,特别是高船龄营运船舶的EEXI指数,以某船龄达到16年的5300 TEU集装箱实船为例,分析讨论方案设计、技术改造方法及具体的方案实施,从实船项目的角度分析高船龄船舶应对现有船舶能效指数要求的难点和可行的解决方案,确定采用限制主机功率加上球鼻艏局部改装的组合方案可保证该船舶满足EEXI指数要求。In order to improve the EEXI index of the existing ship,especially for the high-aged existed operating ships,a 5300 TEU container ship with 16 years ship age was taken as an example,the initial scheme design,the method of the technical transformation and the final specific implementation were analyzed.From difficulties of the high-aged ship project in dealing with the existing ship EEXI,the feasible solutions were discussed.It was shown that by the method combining limiting M/E power with partial modification of the bulbous bow,the ship can meet the EEXI requirements.

关 键 词：高船龄船舶 EEXI 球鼻艏优化 主机功率限制
