针对3000 m起重铺管船的运动性能，对其铺管作业率做了相应的研究。将模型试验得出的规则波运动响应的每个自由度的n个数据点通过样条差值的方法编写到不规则波响应谱中，并采用变步长勒让德－高斯积分的方法求解出船舶不规则波运行的单幅最大值。同时，与SESAM程序软件的计算结果作对比，经研究，验证了该计算方法的有效性。最后，将计算出的一系列单幅最大值与相应校准值作比较，根据海况资料，将所有满足条件的一系列不规则波的发生概率相加，则起重铺管船在特定工况下的铺管作业率得到了求解。

This paper studies the operation capability based on the motions of a 3 000 m pipe?lay vessel. The n data points of each degree of freedom of regular wave response that are derived from model test are input into the irregu?lar wave response spectrum through the spline interpolation method, and the single amplitude's maximum values of the vessel are obtained by using the variable step Legendre?Gauss integral method. At the same time, the calculated result is compared with that of the SESAM software program. This study validates the effectiveness of the proposed method. A series of maximum values of single amplitude are obtained and through the comparison with the critical values, all of the probabilities of relative irregular waves, which meet the critical requirements, are added up and the operation capability of pip?lay vessel under the specific condition is thus acquired.
