In-service buckling of subsea pipelines can occur due to the introduction of axial compressive forces by the constrained expansions set up by thermal and internal pressure actions. Proposed herein is a mathematical modelrelating to a pipeline, the otherwise horizontal and straight idealised lie of which is interrupted by an encounter with an isolated prop or point irregularity. The overbend produced can serve, in the presence of enhancedtopologies involving trenching, burial, discrete or continous, and fixed anchor points, to trigger vertical or upheaval buckling of the pipeline under in-service conditions. The results of a series of case studies are contrasted with data appertaining to alternative models available in the literature: experimental support is additionally noted. By questioning the implicit stress-free-when-straight assumption present in these alternative models, it is considered that a consistent, imperfection-prone isolated propformulation is hereby provided, suitable for design application.
