HYDRODYNAMICS OF LARGE OBJECTS IN THE SEA. PART 2: MOTION OF FREE-FLOATING BODIES

A numerical scheme was developed in Part I utilizing digital computer calculations to determine wave excitation forces as well as added mass and damping coefficients for large objects in the sea. The analysis was carried out within the framework of linear theory for bodies of arbitrary shape, either submerged or semisubmerged, in water of finite depth. In this Part II, an analysis is presented for the motion of large free-floating bodies. The results obtained by methods of Part I are utilized in conjunction with the equations of motion of the floating body to determine the response induced by wave excitation. Numerical results are presented for the response of a sphere and a short, vertical, circular cylinder floating in water of finite depth.
