Abstract:

A series of transverse wave loading tests was conducted on a specially mounted section of pipe in a sediment-filled tank, to investigate the stability of unburied submarine pipelines under wave induced cyclic loading. A major objective was to investigate the vertical pipe displacement as a function of transverse wave loading, as this has an effect on the horizontal resistance of the sediment. A prediction model for the vertical displacement of the pipe has been developed from experimental results. These results are leading to a better understanding of pipe-soil interaction under storm conditions.
