An engineering approach to the time domain analysis which accounts for the effects of damping is developed for the purpose of evaluating the rigid body response motion of a two-dimensional floating body confined in a fixed basin. The frequency dependent added mass coefficients are first obtained under the assumption of an ideal fluid. Then the equations of motion in the frequency domain are constructed by artificially introducing the damping coefficients. The optimum values of the damping ratios are also estimated from the experiments and their use for the analysis of large scale floating bodies is suggested.
