MATHEMATICAL MODEL FOR THE MANOEUVRING SHIP MOTION IN SHALLOW WATER, 2ND REPORT: MATHEMATICAL MODEL AT SLOW FORWARD SPEED

When a ship proceeds to a berth, the captain or pilot reduces or reverses the main engine output, braking the ship's speed. He then adjusts the power of side thrusters or tugs. During the ship design stage, it is very important that the maneuverability under such conditions, in shallow water at slow forward speed, be evaluated. In connection with this need, and continuing work reported upon earlier, this article describes an investigation of steady damping forces and moment acting upon a hull. A new mathematical model is proposed to describe the ship motion at the slow speed involved, a model derived by simplifying a cross-flow model. The model is shown to be applicable to the prediction of complicated harbor maneuvers and to maneuvers associated with single point mooring systems.
