摘　　要：考虑到油船压载吃水在压载工况下的系泊船舶作用力计算、桥梁净空高度设计等工作中是十分重要的参数,但在港口工程中尚无完善的计算方法,现行规范和相关标准的船型资料中亦未提及,通过对大量油船船载AIS数据中压载吃水值的统计分析,得到不同吨级油船不同累计频率下的压载吃水值。将得到的统计结果与国内外几种油船压载吃水计算方法得到的计算结果进行比对分析,为船舶压载吃水的取值和规范修订提供参考。Considering the tanker ballast draft is a very important parameter in the ship mooring force calculation under ballast condition as well as clearance height of bridge design. But in port engineering,there is no perfect calculation method. Ship type information of the current specifications and relevant standards also does not mention. Through statistical analysis of ballast draft values from tankers carrying AIS,ballast draft values of different ton tankers under different cumulative frequency are gotten. The statistical results are compared with the calculated results of several domestic and foreign methods. It can provide a reference for the study of ballast draft and modification of codes.
