基于加权单箱功率指数的集装箱船大型化分析

Large-Scale Analysis for Container Ships Based on Weighted Index of Power per TEU

基于减小单箱能耗的考虑,选择具有代表性的5型超大型集装箱船,通过引入加权单箱功率指数的衡量指标,综合考虑船型尺度、营运航速、均质箱重载箱量,以及吃水状态,分析比较各个因素对于目标船型的单箱能耗的影响,认为从船舶大型化、降速航行、营运时侧重装载轻质均箱因素入手,可不同程度地减小单箱能耗。

Considering how to reduce power per TEU for container ships,the concept of weighted index of power per TEU was introduced to evaluate power level for the subjected five typical ultra large container ships（ ULCS）. Four relevant factors such as ship dimensions,operation speed,number of loaded homogeneous TEUs and draught conditions were analyzed and compared. According to the analytical result,the power per TEU can be reduced to different extent by three ways： enlarging ship scale,decreasing operation speed and loading more light homogeneous TEUs.
