	%X Seabed instability around an offshore pipeline is one
of key factors that need to be considered in the design of offshore
infrastructures. Unlike previous investigations, a three-dimensional
numerical model for the wave-induced soil response around an
offshore pipeline is proposed in this paper. The numerical model was
first validated with 2-D experimental data available in the literature.
Then, a parametric study will be carried out to examine the effects of
wave, seabed characteristics and confirmation of pipeline. Numerical
examples demonstrate significant influence of wave obliquity on the
wave-induced pore pressures and the resultant seabed liquefaction
around the pipeline, which cannot be observed in 2-D numerical
simulation.
