A STUDY ON CONTROL FOR SLEWING MOTION OF A SINGLE ANCHORED SHIP

It is well known that a single-anchored ship often experiences slewing motion caused by disturbances from current, wind and waves. If unrestrained, this slewing motion, in restricted waters, can be detrimental to operations, traffic control and the safety of navigation. In this paper, two types of systems to control such slewing are proposed. The characteristics of both types are analyzed, using simulation of the slewing motion. The first type, named "Wide Control," aims at keeping the ship in equilibrium under conditions where there are external disturbances of current, wind and wave, and is useful for anchorage in unrestricted waters. The second, named "Narrow Control," aims at maintaining a ship heading direction that is coincident with the direction of the current and is useful for control in restricted waters.
