| Abstract: | To enable A/R operation to be carried out without overstressing the pipeline, the deformation of the pipeline is solved by using the spline collocation method while the cable attached to the pipeline is analyzed by employing a line integration technique.The graphical approach is presented for showing the relationship among the deformation and forces of the pipeline and cable,the motion of the lay barge and the tension of the A/R winch. |
