2700m3LPG船总体方案设计与性能计算
设计总说明
本论文是关于2700 m3LPG船总体方案设计与性能计算过程。LPG即液化石油气，本船适装C3 和C4类液化石油气，包括丙烯、丁烯、丁二烯及上述货品的混合液化气。是一首全压式LPG船。
选用本论文主要是考虑到国内经济的飞速发展，对液化石油气的需求量逐渐的增大，而且液化石油气作为高效，清洁，方便使用及储藏量大的能源。但是，由于我国东西部的经济发展和人口数量都极不平衡，东部经济发展快，人口密集；西部经济发展慢， 人口稀少，所以东部的能源需求量较西部大。所以，想要把西部的能源运输到东部，单靠管道运输是很不经济的，而且LPG作为气体能源，管道运输的过程中损耗也较大。LPG船作为一种运输LPG的海上交通工具，对运输成本和LPG的利用率都有大大改善。
LPG船是一种科技含量比通船型高的船，其制造工艺比一般船型都要难和精确，所以我国从开始研发和制造这样一种船型，对我国的造船技术是一种挑战。
根据任务书的要求，本船在设计中采用了球首和球尾，这样可以改善阻力性能，并能提高推进效率。因为本船是海船，吃水不会受到限制，故使用单机单浆。由于LPG属于危险品，本船设有2个1350 m3的卧式圆筒形液化气罐，并有底座支撑，从而省略了双层底结构。设计中将液罐上半部裸露于甲板之上，使得型深较低，这样既可减少船的主尺度，又可提高舱容利用率，同时还方便了船舶的建造和液罐的吊装。
本论文包括了该船的大部分设计过程。由于时间关系，我省略了一些设计步骤，但还是比较全面的完成了设计内容，包括技术任务分析、主尺度论证、总布置设计、舾装设备选型与布置、型线设计、静水力与初稳性计算。

introduction
This paper is about the 2700 m3 LPG Hull overall design and the compute of the performance. LPG is liquefied petroleum gas, the vessel load is appropriate to C3 and C4 LPG, including propylene, butane, butadiene and the mixture of LNG.
Selection of this paper is mainly taking into account the rapid development of the domestic economy, the demand for liquefied petroleum gas gradually increased, and liquefied petroleum gas as a highly efficient, clean, user-friendly and great reserves of energy. However, due to China's east and the west's economic development and population are extremely uneven, the eastern part of fast economic development and population density; slow economic development in the western region, sparsely populated, so the eastern part of the energy demand in the western region. Therefore, to the west to the eastern part of the energy transportation, pipeline transport alone is not the economy, gas and LPG as energy, pipeline transport in the process of loss is also greater. LPG as a transport ship on the sea transport LPG, the LPG transportation costs and utilization rates have improved significantly.
LPG ship is a scientific and technological content than the high-ship ship, its manufacturing process should be difficult than the general ship and precision, from the beginning of China's R & D and manufacture of such a ship to China's shipbuilding technology is a challenge.
According to the book of design target, the ship is designed with the bulb bow and the bulb stern, which can improve, and improve the propulsive efficiency. Because the sea gauge will not be restricted, we use single engine and single screw. As LPG is dangerous, there are two rotund 1350 m3 LPG pot which lie on the ship and is supported by pedestal. Thus the double bottom structure is not necessary. The half of the liquid tank will be exposed on the desk, making the ship lower-deep, which could both reduce the ship’s main dimensions and improve the capacity of the cabin, and also making the building of the ship much easier.
This paper includes most the ship design work. Because of the limited time, I omitted some stage of design, but I still have completed most of the design, including design target, the main scale demonstration, general layout, outfitting equipment selection and layout, type design, hydrostatic and stability calculation, propeller design, etc.
