ON A SIMPLIFIED MATHEMATICAL MODEL FOR AN ONBOARD MANOEUVRING SIMULATOR AND ITS POTENTIAL APPLICATIONS TO SHIP CONTROL.

This paper suggests a simplified mathematical model for an onboard maneuvering simulator. Concerning the human factors affecting maneuvering situations, it seems clearly evident that at least two factors affect the skill requirements of master mariners: familiarity and recency of experience with ship type. So far, the possibility of having on board a real time compact maneuvering onboard simulator would give to ship officers a chance for self-training in a real trim condition in order to quickly achieve the needed familiarity and recency of experience. Lengthy scenario, such as a ship negotiating a long buoyed channel, could be run quickly on a fast time computer in the onboard simulator, enabling the master to anticipate his maneuvering decision result.
