水上过驳装卸工艺系统设计及运输船舶的选择

针对某些国家和地区的航道水深等建港条件受限、大宗散货进口或出运而建设大型码头成本巨大的问题,探讨通过水上过驳系统中转,减少港口建设及营运成本的可行性。结合孟加拉电厂配套煤炭码头的设计过程,探讨如何确定水上过驳装卸工艺系统。采用理论计算和模拟仿真的方式,选择不同的船型组合,合理选择运输船型,并根据乘潮情况确定航道参数。结果表明,采用水上过驳中转系统,可避免大型码头建设及长距离航道的疏浚维护费用,水上过驳成本相对于货物价值影响不大,可作为码头建设一个可行的选择方案。

Handling system design of ship to ship transfer system and selection of transfer vessels

In some countries and regions,due to limited terminal construction conditions such as water depth of channel,and the huge construction cost of the large-scale terminal for the import or export of bulk cargos,we probe into the feasibility of reducing the port construction and operating costs through the transfer of water transfer systems.Based on the design procedure of the coal terminal for the power plant in Bangladesh,we discuss how to select the ship to ship transfer system.By the theoretical calculation and simulation,we choose different ship type combinations and select reasonable transport ship type,and determine the channel parameters according to the tide conditions.The result shows that the ship to ship transfer system can be used to avoid the dredging maintenance cost of large terminal construction and long-distance waterway.The cost of ship to ship transfer operation is relatively small compared to the value of the goods,and it can be used as a feasible option for the terminal construction,and provide a basis for project investment decisions.
