dc.description.abstract	Structures in offshore seabed area is quite common affair.Offshore monopile foundation is one of the most commonly used foundation structures.The Sangu Gas field in Sangu river is an example in our country.These offshore structures are subjected to continuous cyclic load impact caused by sea waves which may cause structural failure and collapse. In this work, a developed numerical method for water-wave body interaction is used to study the water wave’s effects on the structural behavior of the monopiles. A validation procedure will be conducted by comparing the numerical results with analytical wave mathematical model results. The numerical model is based on Reynolds Averaged Navier Stokes equations (RANS) considering the effects of energy dissipation. ANSYS CFX is used to solve (RANS) using finite volume method. The free surface displacements are tracked by the volume of fluid method. The numerical model is used to simulate periodic first order waves and their interaction with a vertical slender monopile. The physical analysis is to be performed in a wave tank model where artificial waves is created using slider crank mechanism operated by an A.C motor.The offshore obstacles considered in the analysis were two types:- cylindrical monopile and square shape monopile.	en_US
