Model tests of lateral loading for surface pipelines on sand

| description | Offshore pipelines are often placed on the seabed surface. For these pipelines the stress induced by thermal expansion, caused by the hot products being transported, can lead to cases of lateral buckling. An accurate assessment of the pipeline's susceptibility to buckling, and therefore an assessment of the pipeline's structural integrity, requires accurate modelling of the pipe-soil interaction, particularly for lateral pipe motions. Previous studies find that the pipe's lateral resistance is dependent on the pipe embedment (relative to the pipe diameter), loading history of the pipe and the soil properties. This paper describes laboratory testing that complements existing experimental data, to allow the development of better pipe-soil resistance models. A pipe with diameter of 100 mm was used in the experiments, and was move up to eight diameters laterally, replicating a typical lateral pipe excursion. The experiments consist of (a) penetration tests, (b) "swipe" tests and (c) probe tests, under constant vertical load, which allow a thorough investigation of the key parameters affecting the lateral soil-resistance for shallowly embedded pipes. © 2010 Taylor and Francis Group, London. |
