8. MCMC2000, Aalborg, Denmark, 25 Aug., 20008 AIS (Universal Ship-borne Automatic Identification System) Static information –IMO number, call sign, height and width, ship type, position of antenna Dynamic information –Ship’s position, standard time, heading angle, course on ground, speed, rate of turn, etc. Navigation information –Draft, type of cargo, departure and destination, waypoints etc. Safety message

9. MCMC2000, Aalborg, Denmark, 25 Aug., 20009 Concept of V-VTS

10. MCMC2000, Aalborg, Denmark, 25 Aug., 200010 Intelligent Marine Traffic Simulation Ship Auto-navigation Fuzzy Expert System (SAFES) (1987-1993) Marine Traffic Simulation System (SMARTS) (1990) Automatic Berthing System (under developping)

11. MCMC2000, Aalborg, Denmark, 25 Aug., 200011 Ship Auto-navigation Fuzzy Expert System (SAFES) Automatic guidance to perform each ship’s mission –Rudder and engine rpm instructions Automatic collision avoidance system –Capable to avoid multiple target ships for any situation including overtaking and speed reduction

12. MCMC2000, Aalborg, Denmark, 25 Aug., 200012 Marine Traffic Simulation System (SMARTS) Arbitrary configuration of gaming area Arbitrary number of ships to be generated Arbitrary setting of each ship condition –OD gates –Average arriving time –Type of ship, speed and dynamics Analysis of safety measures –Statistical data acquisition
