Abstract

The purpose of the present study was to investigate the effect of mariner's situation awareness(SA) training on navigation performance using full mission ship-handling simulator. For this purpose, 20 mariners were trained in terms of various aspects of SA by providing performance feedback, instructions to monitor the radar information, to integrate navigation-related elements, and to anticipate the possible future situation based on present situation. Independent variables such as risk levels of ship-to-ship collision, movement types of target ship(TS), and number of ships around the own ship(OS) were systematically varied, and dependent variables of closest point of approach(CPA) between TS and OS, number of collision, radar detection reaction time, and free recall performance of current situation were measured. The results can be summarized as followings. First, training on mariner's SA appeared to induce improved performances both of ship handling and SA(i.e., mariners in the post-training session showed longer CPA, lower collision rate, faster radar monitoring time, and higher free recall rate than the pre-training session). Second, mariners in the routine navigation situation where TS had priority following maritime rules seemed to suffer to prepare collision avoidance when the TS altered the path. However, this tendency greatly reduced after the training. These results suggest the benefit of mariner's SA training on maritime safety.
