Evaluation of expected maximum values of forces acting on containers and lashing rods on a container ship

The appearance of a number of large container ships in the 8000 TEU range raises the importance of a plan for container lashing arrangements on deck in relation to the design of the ship. Therefore, it is expected that a new method for evaluating the lashing arrangements on deck will be introduced which is applicable regardless of the ship's size and the lashing pattern, instead of using the standards of several different societies, as happens at present. To evaluate the lashing arrangements on deck, the expected maximum values of the forces acting on the containers and lashing rods should be evaluated. This paper presents a new method of evaluating the container lashing arrangements on a container ship using an "acceleration ellipsoid." The applicability of the acceleration ellipsoid to an evaluation of the expected maximum values of the forces was examined by comparing the expected maximum values of the forces calculated by the long-term distribution calculation known as the "Fukuda method," to those calculated using the acceleration ellipsoid. By comparing these results, it was confirmed that the expected maximum values of the forces calculated using the acceleration ellipsoid were not less than those calculated through by the long-term distribution calculation. It is concluded that the acceleration ellipsoid can be used to evaluate the expected maximum values of the forces acting on containers and lashing rods.

半潜船概率破舱稳性浅析

应用国际通用的概率破舱稳性理论对半潜船的分舱情况和破舱稳性进行初步分析.通过大量计算研究舱室垂向水平分隔限制、初始装载状态和边舱几何形状对分舱指数A的关系及影响,得到相关要素间的关系曲线图表和船舶设计指导原则.结合一艘半潜船破舱稳件概率方法的计算实例.针对概率衡准(SOLAS)做出计算结果的理论解释.最后给出半潜船的设计要素,对船舶设计初期指导压载水舱划分和评价概率破舱稳性具有参考价值.     

舰船工程风险演变机理和建模分析

为增强舰船工程风险管理的针对性与有效性,研究了舰船工程风险的演变机理,讨论了舰船工程中的各种风险成分及其相互关系.通过定性分析表明,随着舰船工程阶段的推移,不仅总的风险度是逐渐降低的,而且各种风险成分占总风险的比例也是不断变化的.在此基础上又通过建立数学模型的方法给出了舰船工程风险的演变模型与函数关系,并通过举例给出了风险演变和转化的趋势,进一步验证了定性分析的正确性.本文的研究成果为舰船工程风险的管理提供了理论依据.
