Sažetak
The motion analysis of moored ships is very important factor to consider the berth efficiency during year. The solution methodology consists of modelling a ship as panel model used to calculate the hydrodynamic loads and responses from potential theory. The mooring lines are modelled by ship to ground spring elements. The stiffness of those elements is accumulated into the global restoring matrix for the rigid body equation of motion. The system of obtained differential equations is solved by frequency domain procedure taking explicitly into account the influence of shallow water. The effect of irregular waves is taken into account by appropriate wave spectrum. Illustrative applications of the method are given for a two ferryboats and one cruiser moored on the outside of hypothetic jetty at Adriatic Sea harbour. The irregular sea is described by the Tabain spectrum. The results are presented as comparison of significant ship ramp motion amplitudes and chosen specific criteria limit.
