摘　　要："海洋石油201"号等多艘铺管船在东海海域进行铺管施工时受低频涌浪环境影响横摇运动强烈,严重影响了正常铺管作业。为了分析铺管船横摇过大的原因,从理论上分析了铺管船可能发生较大横摇的波浪条件,并对"海洋石油201"号铺管船在遭遇波浪周期等于横摇固有周期1/2倍和1倍,不同波高的规则波中航向角分别为0°、30°、60°和90°时的运动特性进行了模型试验。试验结果表明铺管船遭遇周期为其横摇固有周期一半的涌浪时未发生参数横摇,而遭遇与其横摇固有周期接近的涌浪时发生谐摇是导致其横摇运动过大的原因。研究成果与相应的气象资料结合,可为铺管船施工气候窗口的选择提供依据。The pipelay vessels such as ‘HAI YANG SHI YOU 201＇. were seriously affected by the low frequency swells in the East China Sea,and the rolling amplitude was too large to lay pipeline normally. In order to analyse the reason,two conditions,parametric rolling,and synchronous rolling,which might be the cause of dramatic rolling were analyzed theoretically and model tests of pipelay vessel ‘HAI YANG SHI YOU 201＇with heading angles of 0°,30°,60° and 90° in swells with different periods and wave heights were carried out respectively. The test data proves that the reason for the dramatic rolling is not parametric rolling which does not occur when swells＇ period is equal to approximately half the natural rolling period,but synchronous rolling will happen when swells＇ period nears barge＇s natural rolling period. The research results combined with meteorological data can provide a basis for the choice of construction climate.
