Abstract

A current problem in maritime education and training using a ship handling simulator is how to judge quantitatively and objectively the skill progress of trainees for collision avoidance maneuvers without depending on an instructor's experience and subjectivity. The skill of performing a collision avoidance maneuver can be judged from the following three points: (1) timely action, (2) suitable operation, and (3) satisfactory result. In the present paper, whether collision avoidance action was taken in a timely way is evaluated with TCPA; whether a suitable operation was performed is evaluated by changes of heading angle; and, whether the result is satisfactory result is evaluated by Environmental Stress Value (ES value) and Time to Collision (TTC) which can be judged from the viewpoint of reducing risk of collision and stranding. A collision avoidance maneuver in a narrow water area is taken up in the case study. A total of 80 repetitions of simulator experiments were conducted systematically, and the validity of these objective indices was examined.
