罐式集装箱是将圆筒形容器装在框架中的特殊形式集装箱,其主要组成部分罐体可以用来盛装粉末状固体、液体(包括低温液体)、气体等。用来盛装液态货物的罐式集装箱最为常见,其材料一般采用316L奥氏体不锈钢,多用来装运化工品,在我国一般称之为不锈钢液体罐式集装箱。虽然奥氏体不锈钢有很强的耐腐蚀性,绝大多数的化工品都可以 相似文献

由于运输操作中的实际需要,对集装箱进行刚强度静力试验是必不可少的。以往集装箱生产厂家通常根据设计经验来设计新箱型,当遇到客户指定结构或特殊结构的箱型时,可能对设计箱体的刚度和强度产生疑虑,需要先制造样箱,并对样箱进行刚强度试验,如果试验结果不通过,再加以完善甚 相似文献

Strain gauges are commonly used for the instrumentation of ship structures to measure ice loads on the basis of shear strain differences. Finite Element Analysis (FEA) is used to determine the load–strain relation of the instrumented area by calculating an Influence Coefficient Matrix (ICM). However, the accuracy of the measurement method and the influence of the load location and load length on the accuracy of the load determination are rarely assessed. Consequently, this paper identifies the accuracy of the ICM, discusses which structures are suitable for measurements of shear strain differences and presents possible improvements regarding these measurements. As load cases are systematically varied over a finite element model, the external load is recalculated based on the resulting shear strains. The number of strain gauges used for the measurement of shear strains has a significant impact on the ICM. For common instrumentation it was found that the ice load can only be accurately determined, if the ice load acts within the instrumented area. To overcome this limitation, an approach to determine the load location is presented among further recommendations. 相似文献

随着集装箱船运输的不断发展,集装箱的安全系固作业也越来越受到重视。为此,国际海事组织海安会对已有的《货物堆装和系固安全操作规则》,即CSS Code进行了修订,补充了有关甲板集装箱安全系固作业的新要求Annex 14,即《指南》,并已于2015年强制生效。文中结合集装箱船设计实例,简要分析《指南》的主要内容以及对集装箱船系固设计的主要影响。 相似文献

<正>集装箱因其装卸及运输标准化,在运输过程中不需换装,适用于多种运输方式。集装箱运输提供的是便利快捷的门到门服务,装卸、运输、通关(反走私/反恐)高效,已经成为重要的全球化运输方式。此外,营运中的集装箱需要开展中间检验和定期检验。正是由于集装箱所具有的特殊性,需要缔约国政府授权一个组织对集装箱的设计、制造、检验及使用等进行检验发证,而将集装箱授权相关船级社检验在国际上属于惯例。在我国,《中华人民共和国船舶和海上设施检验条例》1993规定:中国船级社承办国内外船舶、海上设施和集装箱的入级检验、鉴证检验和公证检验业务。 相似文献

In the present economic climate, it is often the case that profits can only be improved, or for that matter maintained, by improving efficiency and cutting costs. This is particularly notorious in the shipping business, where it has been seen that the competition is getting tougher among carriers, thus alliances and partnerships are resulting for cost effective services in recent years. In this scenario, effective planning methods are important not only for strategic but also operating tasks, covering their entire transportation systems. Container fleet size planning is an important part of the strategy of any shipping line. This paper addresses the problem of fleet size planning for refrigerated containers, to achieve cost-effective services in a competitive maritime shipping market. An analytical model is first discussed to determine the optimal size of an own dry container fleet. Then, this is extended for an own refrigerated container fleet, which is the case when an extremely unbalanced trade represents one of the major investment decisions to be taken by liner operators. Next, a simulation model is developed for fleet sizing in a more practical situation and, by using this, various scenarios are analysed to determine the most convenient composition of refrigerated fleet between own and leased containers for the transpacific cargo trade. 相似文献
