摘要

全面分析一艘沿海货船对排放控制区(ECA)的应对策略，结合船舶航行路径和航速关系，分别建立非规避和规避策略下航行成本最小化模型，对船舶进出不规则ECA边界点位置和航速进行优化，得到船舶最佳航行模式和策略选择。研究表明，规避策略的触发条件取决于ECA内外的燃料价格比及港口与ECA边界之间的相对位置。对中国沿海区域船舶规避情况进行实证分析，结果表明，规避策略既能节约航行成本又能减少航行时间，但会大大降低排放控制区政策的减排效益。

Abstract

In this paper, the response strategy of a coastal cargo ship to the emission control area (ECA) was comprehensively analyzed, and combining with the relationship between the ship’s navigation path and speed, the navigation cost minimization model under non-avoidance and avoidance strategies was established respectively to optimize the location and speed of the ship’s entry and exit irregular ECA boundary points, and resulting in the best navigation mode and strategy selection of the ship. It is shown that the trigger condition of the evasive strategy depends on the fuel price ratio inside and outside the ECA and the relative position between the port and the border of the ECA. The empirical analysis of ship evading in China’s coastal areas shows that the evading strategy can save the navigation cost and reduce the navigation time, but will greatly reduce the emission reduction benefits of the emission control area policy.

Key words： emission control area(ECA); coastal ship; irregular ECA boundary; path and speed optimization; evasion strategy
