| Abstract: |
| Deep-water S-Lay of pipelines requires large deformation and contact analysis in three-dimensional space. It is difficult to be solved due to slow convergence rate. To overcome this problem, a substructure method is presented in this paper. By condensing the degrees of freedom of internal nodes of the stinger, the pipelay problem can be formulated and solved in two-dimensional space. This method has the advantage of fast convergence rate and can be used to carry out extensive parametric studies for pipelay problem. |
