With the current economic growth of our country, many high-speed vessels are coming into the market. Because of their high performances, the safety of navigation between the new high-speed vessels and conventional systems, which include conventional ships, traffic routes and navigation aids, has been required. To establish the navigation safety of high-speed vessels, we conducted "A study on methods of safety assessment by using a simulator for a high-speed vessel" and the study was carried out from 1991 to 1995 with a financial support by the budget of the Research and development in Transportation Technology. This report summarizes the research activities of "A study on methods of safety assessment by using a simulator for a high-speed vessel". Through the study, we proposed an evaluation method for ship navigation by using a ship-handling simulator, safety manners in navigating high-speed vessels and some effective navigational aids for high-speed vessels. This study is divided into three parts. The first part is the improvement of our ship-handling simulator to fit for high-speed vessels and various navigation aides. The study on a safety evaluation method for high-speed vessel is the second part. The last part is the experimental evaluation of a support system to assist high-speed navigation. As the result of simulator experiments under various conditions of our renewed ship-handling simulator, practical safety margin and safety manners of high-speed navigation and the support system were proposed. In addition to those principal results of our simulator experiments, we conducted on-board experiments of encounter between a high-speed vessel and ordinary speed ships. It suggested the way of safety high-speed navigation in a congested area. Through the researches of high-speed vessel' s safety, we also examined effective support for conventional ships that is handled by fewer personnel. This Study will leads to produce the practical support equipment that enables even one-man watch. Furthermore we developed the technique which represents lights of aids to navigation properly in computer graphics imagery of a ship-handling simulator. Results of our study were referred by RR committees in the Shipbuilding Research Association of Japan. Our proposal of the safety assessment of high-speed navigation with a safety margin as an index has been accepted widely in a ship navigation field. The support system for one-man watch is going to be installed in a newly-developed domestic oil tanker. In cooperation research with the Safety Marine Agency, the rearrangement of the Kanmon Passage was effectively assessed using the light expression technique. We hope that a safe and efficient marine transportation system will be realized by using our research results.
