This paper analyzes the characteristics, efficiency and limitations of the AIS, DADAR, VHF during the ship’s collision prevention that the duty officer should takes the reins of all available means and correctly use them in the practice to guarantee the ship’s safety.

The purpose of this thesis is to developing and exploiting an intelligent system for collision prevention,namely “Intelligent Collision Prevention Expert System for Navigation”(NICPES).

This paper makes a brief review of the current study at homeand abroad of themathematical models of the automatic collision preventionsystem.

Finally,the obstacle avoidance plan was carried out and detailed simulation results were given.

Using this method, moving obstacle avoidance can be performed more efficiently.

The paper proposes a new method of real time navigation and obstacle avoidance for mobile robot in dynamic environment.
