Abstract

A mis-handling of the ship operators, treated as one of the main causes of a ship accidents, normally has caused a ship to collide with obstacles like a reef, a rock and other ships etc. since their ability has been declining little by little even though the port conditions have been getting worse. The ship needs a highly sophisticated technology as her size and speed increase as the ship have been demanded. For example, Auto Avoidance Control System gradually has been receiving a growing interest to control the entire ship safely. From that purpose, this research has been done. The research was based on the MMG mathematical model, used Surge-Sway-Yaw-Roll motion equation and Fuzzy theory for calculating the collision-risk. Also the research successively was done when the ship encountered continual multitude ships.

Key Words: Collision avoidance;Ship’s maneuvering;Fuzzy theory;Maneuvering motion equation
