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。
The three-dimensional source-sink method was used to calculate wave induced movement of oil tankers. The hull motion responses of five oil tankers with displacements ranging from 30,000 t to 300,000 t at shallow waters were investigated. By the statistical analysis of the response spectrum, The statistical values of the maximum vertical amplitude of ship bottom under various sea conditions are plotted and the corresponding curve families are drawn, which can be used to determine the minimum safe water depth required by tanker under different sea conditions and water depth conditions.
