Influence of Wave Period on Mooring Motion and Force of a Ship

An engineering practice has been analyzed to explore the influence of wave period on the mooring motion and force of a ship by using OPTIMOOR software. The research results show the increasing of ship movement and mooring force to large extent when wave period is close to ship's natural vibration period. However, the mooring cables to fix a ship follow different rules of variation. Various motions of a ship reflect different sensitivities against wave period and direction. Finally an optimum suggestion is proposed for the ship mooring system.
