Abstract
To understand the behavior of marine structures when submitted to the action of waves, it is necessary to assess the pressure field exerted on these structures. This chapter aims at dealing with the numerical modeling of the second-order wave forces acting on a marine structure in finite water depth. The numerical approach consists in using the finite difference method to compute the fully second-order Stokes wave problem applied to a three-dimensional domain with fixed vertical cylinder. To simplify the meshing task, the fluid domain has been decomposed into subdomains. To ensure the continuity of the transformations and the velocity of these transformations at the level of the contact zones of the subdomains, additional boundaries conditions are required. The results provided in this chapter are to expose the numerical results of the water wave impact on the offshore structure for different water depths and wave heights.
