Abstract:

Shallow sea gas pipelines usually operate in complicated and changeable regional environments and can generate corresponding stresses and displacement under the influence of internal pressures, earthquakes, waves and other loadings. An unevenly distributed stress will lead to shallow sea gas pipeline failure easily. In order to ensure the safety of pipeline, it is necessary to research the stress conditions of the shallow sea gas pipeline and check whether it can meet the safety requirements or not. In this study, we analyze the stress conditions of shallow sea gas pipelines of two laying modes in XX areas using stress analysis software CAESAR II, discuss the loading conditions under the operating condition and determine the position of the key point where pipeline damage is most likely to happen, the bend pipe. The comprehensive experiments show that underground method more secure than the sea-bed method, it greatly improves the reliability of the shallow sea pipeline running. Our research provides a theoretical basis for the construction of shallow sea gas pipelines.
