The scattering of free surface gravity waves by a circular very large floating structure (VLFS) in water of finite depth is studied. The circular platform is assumed to be a large elastic plate with constant flexural rigidity and homogeneous stiffness. The edge of the plate is assumed free of shear forces, bending and twisting moments. The geometry associated with the floating circular plate is assumed to be axi-symmetric. Hence, the mathematical analysis describes the boundary value problem under the linearized water wave theory in the two dimensional cylindrical polar coordinate systems. Using the continuity of velocity and pressure across the vertical plate-water interface and then applying the higher order Fourier expansion formulae along with the orthogonal properties of the eigenfunctions, the full solution is obtained. The reflection and transmission characteristics of the incident wave and the behavior of flexural gravity wave propagation along the plate are analyzed in detail.
