Abstract

In this paper, a theoretical solution of vertical buckling is proposed with regard to the typical initial imperfection cases of submarine pipelines. Analytical tools are applied to predicting the occurrence and consequence of inservice buckling of a buried heated pipeline in Bohai Gulf. An evaluation is performed to ensure the pipeline structural integrity during operation under loading conditions. Different protection measures are proposed and their validities are analyzed. Analyses show that for the same magnitude of initial imperfection, the upheaval buckling of pipeline with isolated prop model is the most likely to occur. The empathetic model represents a special sub-case of continuous prop model, and the calculated buckle temperature is between the first stage and the second stage of post-upheaval buckling of continuous prop model. And the larger the initial imperfection, the less the axial force required for the upheaval buckling. Meanwhile, it can be seen that a peak point appears on the curves of temperature difference against buckling amplitude for small initial imperfection. Besides, trenching-burial is one kind of protection measures preventing the pipeline from thermal upheaval. The covered depth-to-diameter ratio depends on the design conditions and subsoil properties. For the given pipeline in this paper, the covered depth-to-diameter ratio is recommended to be 5.
