It is well known that pipelines may buckle under axial compressive force created by severe temperature change and internal pressure loading conditions. Extensive work has been conducted in the past to understand the beam mode buckling behavior of the pipeline, its impact on pipeline design and, ultimately, the integrity of the pipeline. To fully describe this localized buckling behavior, both the upward and axial displacements of the pipeline need to be considered. This paper presents a large deflection finite-element analysis method with nonlinear material behavior to examine the pipeline response under upheaval buckling condition. The axial displacement caused by thermal expansion and the geometric change of the pipeline due to upheaval motion are examined to better define the pipeline buckling response. By combining both the nonlinear geometry and material effects, it is possible to characterize the extreme responses to determine potential severe damages. A pipeline with a potential for upheaval buckling from a recent North Sea field development was analyzed using the method to evaluate the buckling potential and the pipeline behavior beyond buckling.
