To introduce information technology to bridge watch tasks to enhance navigation safety, we investigated marine disasters and the information at sea. From the statistics of marine disasters, we found that collision and grounding accidents account for 44 per cent of all marine disasters and these accidents were caused mainly by human errors. The needs for automatic information acquisition system, practical collision and grounding alarm system, track control system and good human machine interface were highlighted to avoid collision and grounding. A navigation support systems need a lot of digital information such as information of ships, environment information, sea traffic control information, etc. Nowadays most of information can be acquired automatically except other ship information. But an AIS (Automatic Identification System) appeared and it provides precise information of other ships automatically. Therefore, we evaluated the characteristics of AIS by field test to compare with ARPA. From the results, we found the possibility to improve the performance of the collision and grounding avoidance system by using the accurate and effective AIS information.
