An expert system for monitoring dynamic stability of small craft

This paper describes an intelligent monitoring and advisory system for vessel safety. This system uses environmental information obtained from a number of sensors and proposes corrective action based on a rule-base derived from human expertise, experiments, and theoretical research. The architecture of the monitoring and advisory system is described. Capsizing modes of a ship at sea are explained, and the fuzzy expert system used in the decision-making process is detailed. Simulations of various sea conditions leading to capsize are presented, and the vessel response to the corrective action suggested by the advisory system is illustrated
