基于平吃水进港的北进江航线船舶吃水和吃水差的确定

摘要

北进江航线是内贸运输中的一条重要航线,由于长江水深的限制,深吃水船往往不能满载进港,平吃水进港是提高载货能力的唯一途径.针对驾驶员对平吃水进江的常见错误计算,分析了其错误原因,通过公式给出了平吃水进江要求船舶在长江口处的吃水、吃水差以及北方装货港的最大吃水和吃水差.%The north river course is an important course in domestic transportation, due to the Yangtze River water depth limit, deep draft ship often cannot be loaded with port, port is the only way to improve the flat draft cargo capacity. Aiming at the wrong understanding on flat water into the river pilot, This paper ana-lyzes the causes of the errors, the formula gives the draft into the river at the mouth of the Yangtze River at the requirements of ship' s draft, trim and north to the port of loading to the maximum draft and trim.
