摘要:鉴于2020年后更加严格的限硫规定的实施,在硫排放限制下研究燃油切换和脱硫洗涤两种策略下班轮运输航线配船优化与减排策略选择问题。综合考虑船型、船舶数量、船速、环境等因素,分别建立两种策略下船队运营和环境整体成本最小优化模型,并设计遗传算法进行求解。通过对某班轮公司的航线网络进行实例演算验证模型和算法的有效性。结果表明,与燃油切换策略相比,脱硫洗涤策略的经济效益更加明显,更能减少大气污染物的排放;在油价和硫排放限制下,脱硫洗涤策略显得更具有市场竞争力,能满足班轮公司的减排和利益需求。通过对船舶在硫排放控制区内的航行距离和油价进行灵敏度分析进一步验证了结果。

Abstract:

In view of the implementation of the more stringent sulfur limit regulation after 2020, the fleet deployment optimization and the emission reduction strategy selection of liner transportation are studied under sulfur emission limits and two strategies of fuel switching and desulfurization scrubbing. Considering factors such as ship type, number of ships, ship speed, environment, the optimization models under two strategies are established, respectively, with the objective of the minimum total cost of fleet operation and environment, and the genetic algorithm is designed to solve them. Through an example calculation of a liner companys route network, the effectiveness of the model and the algorithm is verified. The results show that the desulfurization scrubbing strategy is more economical than the fuel switching strategy, and it can reduce the emission of air pollutants significantly; with the limits of fuel prices and sulfur emissions, the desulfurization scrubbing strategy appears to be more competitive in the market and can meet the emission reduction and benefit needs of liner companies. The sensitivity analysis of the ship navigation distance in the sulfur emission control area and the fuel prices further verifies the results.

Key words:

全球航運业正在向低碳、环保方向发展。据IMO官网数据显示,90%的世界贸易依靠海运完成,船舶使用重燃油(heavy fuel oil, HFO)会产生多种对人类、动物、生态和海洋有害的物质。2015年在硫排放控制区(sulfur emission control area,SECA)内实施限硫令后,燃油的改变使颗粒物和SO2的排放量分别减少了67%和80%[1]。在2020年以前,船舶在SECA外航行时不能使用硫质量分数超过3.5%的燃油,船舶在SECA内航行时不能使用硫质量分数超过0.1%的燃油;在2020年之后,船舶在SECA外航行时使用的燃油的硫质量分数必须不超过0.5%,HFO将不能再在SECA内使用。……
