Stress Analysis for Safety Evaluation of Subsea Pipeline Based on Material Properties

Abstract:

Subsea pipeline has been wildly used in the offshore oil exploitation, and its operational safety has profound significance to the subsea oil industry. In this paper, an actual operating subsea pipeline, which is a typical structure of pipe-in-pipe system, is selected as the object of study. Based on finite element method, the stress analysis is carried out. Results show that the residual ultimate strength of the current damaged pipeline is founded and the damage greatly increased the stress state of dented region of the pipeline.
