典型的单壳散货船到现阶段的双壳散货船的发展.doc

摘 要 散货船历经了由典型的单壳散货船到现阶段的双壳散货船的发展。全球经济的快速增长带动了航运界的突飞猛进，散货船的需求也在剧增，其船体结构也在不断的更新、优化和完善。典型的散货船因其单壳形式带来种种的隐患和不安全问题，使得双壳灵便型散货船的出现受到广大船东的喜爱。同时，各国船东对散货船的需求不再仅仅是能装载单一的散货，而是集能装载散货、杂货，集装箱于一体的多用途散货船。 本文通过《钢质海船与入级建造规范》（2006），对104.6 m沿海散货船船体结构进行规范设计。探讨现阶段双壳船船体结构形式以及趋向多用途散货船船体结构形式的一些问题；并编制104.6 m沿海散货船船体构件计算书，对船体结构绘制货舱、机舱、船首部典型横剖面图，基本结构图，典型横舱壁结构图。同时，文中也介绍了本船规范设计的全过程，通过分析本船结构特点，最终可以提高结构的可靠性和稳定性，并对此种方案的合理性做出解释。 关键词：散货船；船体结构；规范设计；结构特点；多用途 Abstract The bulk carrier went through the stage of the typical single-hull bulk carriers to the stage of double-hull bulk carriers. As the rapid progress of the shipping sector driven by the rapid growth of the world economy, the demand for the bulk carriers is severely increasing. Its structure of hull is also constantly renewed, optimized and improved. The typical bulk carriers brought about all sorts of hidden dangers and insecurity problem because of its single-hull form. So the emergence of double-hull bulk carrier is fit to the majority owner of preference. At the same time, the demand of the owners is no longer just able to carry a single bulk, but will carry casual, groceries, set the container integrated with multi-purposes bulk carrier. Based on the CCS “Rules and Regurations for the Construction and Classification of steel ship” (2006). The hull structure of the 104.6 meters coastal bulk carrier was designed. Author discussed the same problems at hull structure of this stage double-hull carrier and trends of multi-purpose bulk carriers, working out the calculated book about hull component of the 104.6 meters coastal bulk carrier. Mapping the typical cross-sectional diagram of the bay、cabin and the bow of carrier, basic structure diagram, typical cross bulkhead structure diagram. Meanwhile, it also introduced a standardized design of the ship throughout the whole process. By analyzing this structural characteristics ship of the ship, the dependability and stability of the structure can be eventually improved, and the rationality of thi
