Summary

 
This paper gives analytical and numerical simulation results for pipeline system under external hydrostatic pressure takin into account variation of bending moments and longitudinal forces along the pipeline. The most loaded areas were studied numerically, in shell and solid formulation. More accurate bearing capacity calculations were performed taking into account maximum acceptable geometric and physical deviations of pipeline elements from regular shape. This study made it possible to develop an approach to taking into account joint effect of multiple loads upon bearing capacity of thick-walled shells in pipeline systems, as well as to give practical recommendations (based on current regulatory documents) on how to ensure reliability of overboard pipelines for deepwater submersibles.
