An efficient computer program for predicting the dynamic response (movement and stress) of submarine pipelines to storm waves and current has been developed. The pipeline is assumed initially straight, is moving on a horizontal plane (bottom) and is exposed to loading from waves and current. The structural response is based on small displacement theory. The increase in the axial force in the pipe due to bending deformation is included. Simulations of the dynamic response are presented in computer plots. Typical results are given for both single element (pipeline section) systems and long pipes, simple and history dependent soil models for sand and clay, and regular and irregular sea states. |
