EXPERIMENTAL AND THEORETICAL STUDIES IN SUBSEA PIPELINE BUCKLING

Field failures of trenched and/or burried subsea pipelines due to in-service buckling have recently been admitted in literature. This paper presents the results of a recently completed series of model tests involving full thermo-mechanical system representation. The problematical vertical buckling mode, applicable to trenched and/or buried subsea pipelines, is considered in terms of both isolated prop and contact undulation imperfection topologies. Experimental data is compared with that obtained from a suite of computer-based theoretical models. It is contended that highly satisfactory experimental/theoretical correlation is provided regarding definition of the crucial upheaval buckling state subject to adequate imperfection specification.
