The wave induced cyclic shear stresses in oceanfloor sands may cause a progressive build up of pore water pressure, leading to instability of the bed. This may constitute an important consideration in the analysis and design of various offshore engineering facilities. This paper presents a simplified procedure for the analysis of wave-induced pore pressure in the oceanfloor sands. A simple model for the generation of pore water pressure is used and the effect of its simultaneous dissipation, is also included in the analysis. Numerical solution is also presented in a set of curves which can be conveniently used to evaluate the wave-induced liquefaction potential of an offshore site with deep cohesionless sediments.
