DYNAMIC RESPONSE OF FLOATING BODIES

A numerical scheme is developed utilizing a Green's function and digital computer calculations to determine the excitation forces and moments as well as added mass and damping coefficients for floating bodies. The analysis is carried out within the framework of linear theory for bodies of arbitary shape, either submerged or semi-submerged, in water of finite depth. The calculated hydrodynamic coefficients associated with both the wave excitation and response of the body are utilized in conjunction with the equations of motion in order to determine the response of a free-floating body to wave excitation. In addition, the steady-state drift force and uplift force are discussed for the case of free-floating and fixed bodies. Numerical results are presented for several configurations.
