In the present report, attempts are done to analyze problems of information processing and decision-making of human pilots in berthing maneuvers of large ships and to specify supporting procedures for them from the view-point of human engineering. At first, the procedures to supply the information on ship situations to a pilot are proposed for both maneuvers of approaching and berthing. It is pointed out that a pilot meets with a difficulty in grasping the situations of control devices because of too much information from various routes and a kind of one board display system is recommended for showing compactly the situations of control devices. The problems in the communication among a pilot, captains of tugs, operators on a berth and assistant members in a bridge are also discussed in detail. Lastly, several problems are discussed for improving the system performance as a whole.
