Abstract :
An ANN based system has been developed for forecasting the roll motion of a ship and predicting the onset of parametric roll resonance. This kind of instability can be devastating for the ship and is a phenomenon that is difficult to predict when using classical mathematical modeling approaches. In the present investigation the ANNs are trained using data obtained from a mathematical model of ship roll motion while the performance of the whole system is verified with realistic towing tank tests. The results achieved are quite promising and support the claim that it can be implemented in any ship without the need for any kind of water tank or real ship tests.
