吃水随航道水深变化时的船型论证方法

Study on Demonstration Method of a Ship When its Draft Constrained by Route Water Depth

本文提出了当航道水深变化对船舶吃水有影响时,可通过船舶年平均装载率和年货运量对船型作技术经济论证的思想,并对相应的船型论证的方法进行了研究和讨论.以川江油船标准船型论证为例,证明以本文思想和方法设计的船型比按传统方法设计的船型在主要技术经济指标方面均有显著改善.

The paper presents a new idea and a method for ship technical and economic demonstration based on ship’s yearly Load Rate when its actual draft changes with the route water depth, and the research and discussion on the method of ship demonstration on are also carried out. Through an example of designing a standard type oil tank navigating in Chuan Jiang River area, it is proved that a ship designed with the method will make the ship’s technical and economic properties be more better than that designed with traditional ideas and methods.
