Abstract:	The present paper considers the problem of control automation for passing of ships. A system of intelligence support of mariner’s actions for ships passing is described. The system was designed as a program module intended to be used in the structure of Electronic Chart Display and Information System (ECDIS). The program module allows a set of safe and optimal, from the economical standpoint, passing tracks to be synthesized based on the information about motion parameters of own ship and other vessels. In doing this, proper account should be taken of sailing conditions and navigational hazards. A set of recommended passing tracks is displayed for the mariner to take the final decision about the further ship’s motion. All tracks satisfy the requirements of the International Regulations for Preventing Collisions at Sea (COLREGS) and allow, if possible, the ship to return on her initial programmed track. The problem of track synthesis has been proposed and solved as a problem of fuzzy optimal control that results from fuzzy COLREGS requirements. Each recommended track is characterized by the safety measure which is expressed as a probability of lack of collision for own ship with other dangerous vessels. This probability is calculated based on an intelligence multiagent model for actions of other vessels.
