Horizontal displacement, uh1 of foundation on clay in the offshore Niger Delta has been attempted based on wave load simulation. Horizontal forces were evaluated from the impact of varying wave heights on circular piles of 1.0 to 2.0m diameter using available wave height records. Predictive lateral displacement under induced horizontal forces were analysed for varying Poisson ratio,µ foundation breadth, B and the ratio of horizontal force to breadth ratio(F/B). The results revealed that uh1 reduces with foundation breadth, Poisson ratio, and F/B ratio, while dimensionless plot of ratio of horizontal force to undrained shear strength, foundation breadth and lateral displacement versus Poisson ratio showed that at µ=0.5, both methods of modified Bell and modified Gerrard and Harrison converge. Generally, higher lateral displacement occur using modified Gerrard and Harrison method at lower values of µ.
