新型双燃料船对水路运输的影响分析

Analysis of the influence of new type dual⁃fuel vessel on waterway transportation

物流业的高速发展和国际贸易的不断深入,水运仍然处于很高的地位。为了实现“碳中和”目标和迎合可持续发展,绿色水运成为了热点话题,进而双燃料船应运而生并成为其中极具潜力的发展方向。因此,本文收集了柴油⁃天然气和重燃料油⁃天然气双燃料船的相关信息和数据,以评估不同双燃料推进系统的环境与经济效益。研究发现,相较于单燃料船,采用不同推进系统、不同燃料的双燃料船均能显著减少船舶污染物排放,降低水运成本。其中,双燃料柴油电力推进系统的环境效益最高,且该系统在使用柴油和天然气作为燃料时节约的成本最多。

Water transportation is still in a very high position with the booming logistics industry and global trade.Dual-fuel vessels have emerged as one of the promising development directions as carbon neutrality and sustainable development have become prominent topics in the issue of green water trans⁃portation.Therefore,in order to assess the environmental and economic benefits of various dual-fuel pro⁃pulsion systems,this paper compiles information and data on diesel-natural gas and heavy fuel oil-natural gas dual-fuel vessels.According to the study,dual-fuel vessels with various propulsion systems and fuels can all significantly reduce pollution emissions and lower water transportation costs when compared to single-fuel vessels.The dual-fuel diesel-electric propulsion system,which uses both diesel and natu⁃ral gas as fuel,provides the greatest environmental benefits of all of them and saves the most costs.
