This paper deals with the analysis of the dynamics of a passively damped class of floating platforms during their heave oscillations on the wavy sea surface. The passive damper mechanism has been suggested as a simple means for attenuating the amplitudes of such oscillations. The design parameters of the damper are determined for different wave conditions and platform configurations, by reducing the damper-platform system to an interconnected system of two bodies supported, on a rigid base, by an equivalent wave-spring and dash-pot. The obtained results show that the build-in-damper mechanism can be very effective in stabilizing the off-shore floating platforms and, in particular those with limited draft. (Hannebauer)
