Using the rotation center and pivot point to optimize vessel's maneuver.

Abstract

Optimization of the vessel's maneuver is associated with the need to reduce the maneuvering space. This is especially true for all sorts of narrowness and ports. More accurate knowledge of the behavior of the vessel is required to minimize maneuvering space. By now, three directions of movement optimization have been identified. The first direction is associated with a more accurate determination and taking into account the position of the vessel's rotation center in the control of the rotational motion. The second direction is associated with the use of the Pivot Point in control. More than 85% of all vessels have a traditional stern rudder control scheme. When the stern rudder is deflected, a torque and a lateral force occur simultaneously, which leads to simultaneous rotational and lateral movement of the vessel. Such complex movement is difficult for the navigator to evaluate and make the right decision, which can lead to serious consequences. The third direction is associated with the use of mathematical methods for optimal control of the vessel's movement in automatic mode. This direction in relation to the control of the vessel's movement around the Pivot Point has not been found by the authors in open sources.
