摘　　要：为更方便地研究船舶能效营运指数(EEOI)的影响因素,以46 000t油船为目标船,将其顶浪直线航行时受到的影响因素按蒙特卡罗方法分为确定因素和随机因素。通过运用软件对目标船能效进行仿真建模,获得了EEOI随时间的变化关系曲线;在此基础上,进一步计算和分析海浪特征波高和船舶载重对EEOI的影响。结果表明,提高载货率能够直接提高船舶的EEOI;降低主机转速也是有效降低船舶EEOI的方式,并且这种降低的效果会随海浪特征波高的增大而减少。该方法对单船能效管理方案的制定具有一定的参考价值。To study the influence factors of energy efficiency operation indicator （EEOI）,an EEOI model is established with the aid software,taking a 46000-ton oil tanker as an example.The factors affecting EEOI are divided into determined factors and random factors by the Monte Carlo method.The curves of EEOI vs time are obtained and analysis of the influences of the characteristics wave height and load on EEOI is further made.Results show that improving the loading rate and reducing engine speed effectively improve the EEOI but the effect reduces as height of wave increases.The method helps in making energy efficiency management scheme.
