Abstract
A mathematical model describing the fundamental physics of a ship/ ramp/barge system, including a passive isolator, is developed. The model properly accounts for hydrodynamic proximity effects and structural coupling between the bodies. A standard second order model is used, for demonstration purposes, in order to model the frequency response properties of the connecting body. Parametric studies of the response amplitude operator of the ramp motion are performed for varying wave directions and isolator stiffness and damping. These are utilized for the random wave analysis in standard fully developed seas. The results indicate that rational selection of isolator properties can result in significant reduction of motions and stress levels in the connecting ramp.
