摘要

考虑排放控制区（ECA）边界宽度的影响，建立了以船舶总运营成本最小为目标的混合整数非线性规划模型，以优化减排策略和航速，并以某公司的东南亚航线为例进行求解和敏感性分析。结果表明：不同减排方案的成本比较主要受燃油价格水平的影响，碳税对不同方案的成本比较结果没有影响；从当前的各种燃油价格来看，安装脱硫塔是经济性最好的一种减排措施，其他依次为ECA内外燃油转换策略、使用MGO燃油策略、使用LNG燃料策略；随着ECA边界宽度的减少和不同燃油价格差的减少，燃油转换方案的成本将低于安装脱硫塔方案；使用LNG燃料的初始投资成本降至80%以下或LNG燃料的价格降至50%以下，而MGO燃油价格保持不变或更高时，使用LNG燃料将比使用MGO燃料成本更低；ECA边界宽度的制定会对航运企业的减排策略产生影响，可以通过适当增加ECA边界宽度来减少船公司在ECA内外进行燃油转换的行为。

Abstract

Considering the impact of the boundary width of the emission control area (ECA), a mixed-integer nonlinear programming model is established with the objective of minimizing the total operational costs of the vessel, thereby optimizing emission reduction strategies and sailing speed. The Southeast Asian route of a certain company is taken as an example for solution and sensitivity analysis. Results show that the cost comparison of different emission reduction schemes is mainly affected by the level of fuel oil prices, while carbon taxes have no impact on the cost comparison results of different schemes. From the current various fuel oil prices, desulfurization towers installation is the most economical emission reduction measure, which is followed by the ECA internal and external fuel conversion strategy, using MGO fuel strategy, and using LNG fuel strategy, respectively. As the width of ECA decreases and the difference in fuel oil prices decreases, the cost of fuel conversion schemes will be lower than that of installing desulfurization towers. When the initial investment cost of using LNG fuel is reduced to 80% or less, or the price of LNG fuel is reduced to 50% or less, while the price of MGO fuel is invariable or higher, the cost of using LNG fuel will be lower than that of using MGO fuel. The setting of the ECA width will affect the emission reduction strategy of shipping companies, while by appropriately increasing the width of the ECA, the behavior of ship companies switching fuels inside and outside the ECA can be reduced.

Key words： ship emission reduction; emission reduction measures; emission control area（ECA）; boundary width; optimization of sailing speed; mixed integer nonlinear programming
