Abstract
A system is disclosed for dynamically stabilizing a ship in high sea states. A six degree-of-freedom robotic arm is attached to the ship, and a thruster is located at the distal end of the manipulator. The manipulator is be used to orient the thruster to counteract wave forces that act against the ship's hull in real time. This active balancing technique can be used to keep the ship substantially erect in rough seas by making continual corrections to the ship's body attitude. The center of gravity and the center of buoyancy of the ship are utilized, along with a precisely oriented and controlled thrust at the end of the manipulator, to optimally control the ship's state against impending waves.
