珠江水系江海直达集装箱船技术经济论证

A Techno-Economic Evaluation of the Non-Stop River-Sea Container-Ship for the Pearl River System

根据西江航道航距短、水深小的情况 ,考虑变吃水的运输方式 ,综合分析近年来相近的江海直达集装箱船技术性能 ,以船长 (L)、船宽 (b)、吃水 (T)及航速 (v)作为变量来进行船型方案的组合 ,选用净现值、内部收益率、投资回收期、必要运费率和综合经济指标作为衡量船型方案的标准 ,用网格法对船型方案进行二次优化 .通过分析计算 ,最佳的船型方案为 :L =96m ;b=1 7.5 5m ;T =5 .0m ;v =1 1kn .

The techno_performances of similar sea_river container_ships are synthetically analyzed. Based on the fact that the Xijiang River is characterized by its short voyage and small water depth, a variable draft transportation mode is adopted. The ship's length, width, draft as well as the speed are regarded as the variables which are used to form the ship type schemes. The Net Present Value, Internal Rate of Return, Pay_Back Period, Required Freight Rate and Combined Economic Index are selected for the criteria to measure the ship type schemes. The optimization scheme is obtained through the dual_optimization on the ship type schemes by using the grid method. The optimization scheme which is presented in this paper is L =96 m, b =17.55 m, T =5.0 m and v =11 kn.
