摘要造船业是一个现代化的综合性特别强的产业，它为多种行业提供技术设备，如水上交通行业、海运开发行业和国防建设行业。它不仅资金投资量大，而且劳动、技术密集。现代造船业也对多种行业发展起到带动作用，例如机电行业、化工行业、钢铁行业、航运和海洋资源勘采行业。这些行业基本离不开造船业。由于造船业对其他行业的这种作用，它对拉动就业、发展贸易和保障国防民生都有重大意义。58911

船舶制造是造船业核心的一环，具有工作量大、工种多，制造周期长等特点，需要一个不断完善的体系来统筹兼顾。而船体生产设计作为船舶建造中不可或缺的一环，是课本理论与现实生产之间的一个结合体。一个良好的生产设计不仅可以减少工作量，避免工作中一些不必要的困难，而且可以缩短建造周期，节省生产成本。

本次毕业设计是27500液化气船底边舱401PS的生产设计工作，结合以往的相同类型的船舶的生产设计，来完成本分段的生产设计工作。前期了解船体详细设计，然后完成401PS底边舱分段的生产设计工作。该分段是双层底、双舷侧结构，完成包括结构图，节点图等图，完成分段零件表的编制工作。

Abstract Shipbuilding industry is a modern and comprehensive industry, it provides technical equipment for a variety of industries, such as water transportation industry, the development of the industry and the development of national defense industry. It is not only a large amount of capital investment, and labor, technology intensive. Modern shipbuilding industry also plays a leading role in the development of various industries, such as mechanical and electrical industry, chemical industry, iron and steel industry, shipping and marine resources exploration and mining industry. These basic industries cannot do without the shipbuilding industry. Because of this role in the shipbuilding industry to other industries, it is of great significance for stimulating employment, development trade and protect the livelihood of the people of defense.

Shipbuilding is shipbuilding core of a ring, with heavy workload and more types of work, the manufacturing cycle is long, etc, need a continuous improvement of the system to take all factors into consideration. Hull production design, as an integral part of the ship construction, is a combination of textbook theory and practical production. A good production design can not only reduce the workload, avoid some unnecessary difficulties in the work, but also can shorten the construction cycle, save production costs.

This time, all I did was 27500 liquefied gas bottom side tank 401 PS production design work, combined with previous the same type of ship's production design, to complete the production design work of this section, Early know hull design in detail, and then complete the production of 401 PS bottom tank section design work. This section is the double bottom, double side structure, complete including structure, node figure, such as figure, develop segmented parts list.
