A fault tolerant control strategy for ship stabilization using ballast systems

Abstract

This paper tackles the problematic of ship stabilization using a fault tolerant control strategy. The control strategy can be implemented to use optimal amounts of resources, during the loading and unloading operations on docked vessels. A mathematical model linking the ship's positioning and orientation with the forces and moments exerted upon the hull is required in order to develop an optimal control strategy for the ship's stabilizing ballast systems. This strategy is designed using graph theory concepts, taking into account the ballast system's topology, we can generate an optimal command sequence in respect to minimum energy consumption and tolerance to faults.
