Tensioned beam theory is used to calculate displacements and moments of free spanned portions of offshore pipelines. The Rayleigh method is implemented to calculate the fundamental frequency of the pipeline span under the effects of residual tension and span-induced moments. This procedure is simple and yields a more accurate natural frequency of the pipe even with low residual tension. The effect of the residual tension and span-induced moments on the deep water pipeline was investigated. The benefit of controllable residual lay tension in the pipe was identified. This simple analytical procedure can be applied to offshore pipelines of any size and in any water depth.
