This paper describes a mothod of analysis for evaluating the portion of ship kinetic energy and impact force transmitted to a berthing structure provided with fenders which have linear or nonlinear spring constants. In the analysis, presented herein, the dynamic responses of the ship, fender and berthing structure, after impact, are considered, and derived equations for the selection of different parameters needed for the solutions of the dynamic equations are included. These are comprised of the virtual mass of the ship, in both translational and rotational motion, in addition to the time interval required for the solutions of the motion equations by numerical integration methods.
