摘　　要：采用三维源汇法对油轮的波浪诱导运动进行了系列计算,考察了排水量从3.0万t至30.0万t的5艘油轮在浅水海域规则波下的船体运动响应,通过响应谱的统计分析,获得了各种海况条件下船底最大垂向运动幅值的统计值,并绘制了相应的曲线族,可用于确定油轮在不同海况与水深条件下所需的最小安全水深。3-D diffraction theory is used to calculate a series of the wave induced motions of oil tankers. The motion responses of five tankers with displacement from 30000 to 300000 tons in shallow sea and under regular wave are investigated, through statistical analysis of response spectrum. the statistical values of the maximum vertical amplitude of tanker bottom motion under various sea condition are obtained and demonstrated in a group of curves. with which the minimum safe water depth for oil tankers under different sea conditions can be determined.
