为保证海洋管道在收弃管作业过程中不发生屈服 ,利用样条函数配点法分析了管道的变形 ,利用线性积分法分析了缆索的收放和受力 ,以图表的形式给出了管道和缆索的受力和变形、铺管船的运动以及 A/ R绞车的拉力之间的关系 In order to ensure that the offshore pipeline does not yield during the operation of the reject pipe, the deformation of the pipe is analyzed by using the spline function point-point method. The linear integration method is used to analyze the retraction and stress of the cable. The chart shows the pipe and The relationship between the force and deformation of the cable, the movement of the pipelayer and the tension of the A / R winch
