为应对IMO提出的日益严格的排放法规，降低船舶EEOI值，本文分析了EEOI的数学计算公式以及简化公式，并以某8063TEU大型集装箱船为目标船，基于MATLAB/Simulink建立了船舶能效系统的仿真模型。通过仿真研究，分析了船舶航速、航期、载货量、航程对船舶EEOI的影响，同时研究分析了EEOI对航速、载货量、航程变化的敏感性。结果表明随着航期的增加船舶EEOI逐渐减小；EEOI对航速的敏感性最高，对载货量的敏感性其次，而对航程的敏感性较低；降低主机工作负荷从而降低航速，以及提高船舶载货量都能有效降低船舶EEOI值，而增加航程则对降低EEOI值效果不明显。
With the stringent emission regulation proposed by IMO, this paper analyzed the EEOI formula and the simplified one in order to find a way to reduce the respective EEOI value of the ship. Taking one 8063TEU containership as the target ship, the ship energy efficiency system model was built in MATLAB/Simulink environment. The impact of the voyage speed, the sailing period, the full rate as well as voyage distance on the EEOI were analyzed through the simulation, respectively. Additionally, the research investigated the sensibility of the voyage speed, the cargo capacity and the voyage distance by the EEOI. The study indicates that the EEOI decreases as the rise of the sailing period. Besides that the EEOI has the most impact on the voyage speed sensibility, and the cargo capacity is less influenced whereas it has the least effect on the voyage distance. The lower load of the main engine leading to the corresponding decline of the voyage speed and the growth of the cargo capacity will reduce the EEOI value effectively. However, the increase of the voyage distance does not have a sparkling effect on the reduction of the EEOI.
