In shallow water, hydrodynamic forces and moments acting on the rigid body among waves become different from those in deep water. In this paper, firstly two-dimensional linear radiation problem is solved using Green's function [I] of finite water depth and then hydrodynamic quantities such as added mass, added moment of inertia and damping coefficients of the rigid body are calculated. Secondly, the forced swaying test using the two-dimentional model is carried out to confirm the validity of the above calculation method. As the result of the test, this method is confirmed to be valid in the linear theory. Lastly, as an application of the above method, ship motions among rugular waves in shallow water are predicted by strip method.
