随着客滚船运输行业的兴起,客滚船的营运安全日益受到各方面的关注。文中利用BP神经网络评价方法,由人、船、环境、管理四要素所构成的客滚船营运风险进行评估,最终确定某客滚船具体航次的营运风险。经过验证,基于BP神经网络客滚船营运风险评估方法与实际相符,为客滚船风险评估提供一条新的途径。 相似文献

岸坡道是滚装码头结构中连接滚装船和码头的关键部位。针对短跳板滚装船(一般指跳板长度小于5 m)岸坡道的设计问题,对中外规范相关规定进行分析,结合非洲某工程案例,对比分析不同跳板长度滚装船靠泊结果。结果表明,当设计水位差小于1. 5 m时,可按照规范要求采用固定式岸坡道,但是短跳板滚装船存在跳板脱离岸坡道或仰角过大的风险;设计岸坡道前宜先判断尾跳板端部可调节的垂直高差是否大于设计水位差与满载空载吃水差之和,当前者小于后者时,在不具备采用可调式岸坡道的情况下,可采用多级固定式岸坡道(不同顶高程)来解决滚装船的靠泊问题。 相似文献

汽车滚装码头高程研究 总被引:1,自引:0,他引:1
结合上海港外高桥港区6期工程汽车滚装码头设计,并根据汽车滚装船跳板作业的特殊要求,分别采用基于跳板作业高度要求和基于跳板作业时间要求的2种方法计算高桩梁板式汽车滚装泊位码头面高程。计算结果和实际靠船实践证明,采用这2种计算方法对高桩梁板式汽车滚装泊位码头面高程进行控制是合理的,也是经得起实践考验的。 相似文献

滚装船中车辆等重载荷由于固定装置失效而随船摇荡作自由滑动时,往往由于反复碰撞致使在甲板上作自由滑动的重载荷随着时间增多.由于波浪和内部滑动车辆共同作用,使滚装船的横摇加剧.这是许多滚装船发生倾覆的重要原因之一.本文对由滚装船和两辆滑动车辆组成的浮基多体系统,取滚装船的横摇角和两辆自由滑动车辆在甲板上的横向位移为此系统的三个自由度,运用多体系统动力学方法,建立了系统的动力学方程.以某型海峡滚装渡轮为例,对在两辆车自由滑动和波浪共同作用下的滚装船浮基多体系统的横摇响应和车辆位移响应进行了数值计算,得出了多个自由滑动的重载荷因相互碰撞在舷侧舱壁的约束下随着时间的延长其运动将趋于同步的结论. 相似文献

ABSTRACTCombining ro-ro shipping and tractor-and-semitrailer swap transport under land-sea combined transportation can reduce operating costs and improve the safety of maritime transport. In addition, selection of the tractor-and-semitrailer swap mode (i.e., the ship-swap mode and port-swap mode) is a critical factor that affects the efficiency and cost of ro-ro ship loading/unloading. Considering inland pickup/delivery and ship loading/unloading, this paper develops a model that determines the mode of tractor-and-semitrailer swap transport with the objective of minimizing the total cost. This study also considers constraints such as empty semitrailer exchange and multiple time windows associated with customer receiving/delivery locations and the ro-ro ship. A hybrid simulated annealing (SA) is applied to solve the problem. By analysing numerical examples, the results show that the port-swap mode is more suitable than the ship-swap mode when the number of tasks is large because the port-swap mode can perform more tasks with fewer tractors than the ship-swap mode and because the port-swap mode can service receiving/delivery locations and finish ship loading/unloading more punctually than the ship-swap mode. Thus, this research provides a useful reference for road transport carriers and port firms to select the mode of tractor-and-semitrailer swap transport for ro-ro shipping. 相似文献

Common effect of wave and slip of internal heavy load will make rolling of the roll-on ship serious. This is one of the important reasons for overturn of ro-ro ships. The multibodies System with a floating base is composed of ro-ro ship and slipping heavy load. This paper takes the rolling angle of the ship and the transverse displacement of the heavy load on desk as two freedoms. Making use of analysis of apparent gravitation and apparent buoyaney, the wave rolling moment is derived. By use of dynamic method of multibodies system with a floating base, dynamic equations of the system are established. Taking a certain channel ferry as an example, a set of numerical calculation have been carried out for rolling response of the ship and displacement response of the slipping heavy load under common effect of synchro-slipping heavy loads and wave. 相似文献
