In modern shipping industry, the oil-feed unit, which provides power for ship, is an important component. 在现代造船工业中,作为船舶动力部分的供油单元是整个船舶的重要组成部分。
Typical shipping line is taken as an example, in which unit cost is calculated through voyage estimate and sensitivity analysis is done according to different factors. Direct transport and transhipment mode is researched for the selection of suitable carrier. 以典型航线为实例分析,通过航次估算得出各备选船型的单位货载运输成本,并进行敏感性分析,分别研究了直达运输和中转运输模式下的单位成本,最终选出各情况下的适宜船型。
However, the current energy-saving technologies of shipping industry are mainly about the development of ship types and the optimizing of power unit, which means that the study on energy-saving technology of marine electric power system is defective. 然而,目前的船舶节能技术主要体现在船舶船型节能、优化动力装置等方面,针对船舶电力系统的节能技术研究相对欠缺。
