Abstract: The damping, added mass and mass moment of inertia of a shipmodel, performing forced heaving or pitching oscillations in calm water, are determined experimentally. The influence of model speed, amplitude and frequency of the motions on these quantities has been studied. The coupling terms in the case of a combined heaving and pitching motion are considered for one model speed. Some of the experimental results are compared with calculated values, which have been published recently.
