LATERAL RESISTANCE OF MARINE PIPELINES ON SAND

Within a wider research investigation of lateral stability of marine pipelines, a geotechnical investigation was carried out to examine lateral resistance to movement. It included extensive full-scale tests on a nominal 10 inch pipe on sand, under a range of loading conditions designed to simulate the loading history of a pipeline on the seabed. The results showed that the lateral resistance is actually higher than is generally assumed. The effect is particularly marked when the loading is cyclic with increasing amplitude, and when the pipe is partially embedded in the seabed.
