MOTION CHARACTERISTICS OF FLOATING BODIES

The motion characteristics of floating bodies, in and below a free surface, that are subject to surface waves are examined. The effects of various degrees of approximation of hydrodynamic coefficients on the results of the motion computations are investigated on the basis of linear theory. The behavior of hydrodynamic coefficients such as added mass, damping, and wave-exciting force with respect to frequency of oscillation (or wave length) and depth of submergence is also investigated. Numerical results are obtained for three cylindrical bodies of circular, rectangular, and rhombic cross sections. The results reveal that fairly crude approximations can be applied to compute the oscillatory motion of submerged bodies.
