Paper Title
Finite Element Analysis for Suspended Submarine Pipelines During Installation

The stresses induced in submarine pipelines during installation for static analysis are investigated using the finite element method. Statically analysis of the pipelines during installation process is characterize by gathering of geometrical nonlinearities and excessive flexibilities of the system, assuming the pipeline is an elastic body, and not subjected to environmental loads. Improving and validating of the nonlinear FEM model for emulation and control of the elastic pipeline was done by using computer code ANSYS Release 11. Influence of applied tension force and pipe wall thickness on the deflections and bending moments are investigated.
