Abstract

The thesis investigates whether conventional geotechnical design approaches for cyclic loading of offshore foundations are appropriate for shallow skirted foundations used with the new architecture of offshore developments. The foundation response in normally consolidated kaolin clay is investigated in the centrifuge under vertical cyclic loading, indicative of that applied on foundations used to moor tension-leg platforms, and under horizontal cyclic loading, indicative of that applied on foundations of zero-radius bend subsea structures during pipe-laying. The observed response is compared with that predicted using the traditional accumulation procedure on contour diagrams of shear strain based on direct simple shear tests.
