Abstract:

This report describes the results of experiments using the Maritime Administration Computer Aided Operations Research Facility CAORF ship maneuvering simulator to determine if training in the changes to the steering rules of the Internatinal Rules of the Road 1977 causes a difference in watch officer behavior in the crossingmeeting collision situations. An additional objective was to determine the differences between two ship types VLCC and containership in the same situations. A tightly structured, counterbalanced mixed design with one between- and three within-subject variables was applied to eight realistic experimental scenarios. All scenarios involved failure to give way, in five or twenty-five degree crossings, between a 25 knot containership and a 15 knot VLCC. A half-day, classroom training program, using a soundslide presentation and case study discussions, was effective in increasing knowledge and understanding of the Rules changes. Transfer of training to the simulator did occur with the trained group. Consistency of performance range to target ship at maneuver was significantly improved, fewer course changes per maneuver were made, and better advantage was taken of the rule pertaining to ambiguous meetingcrossing situations by the trained group. The closest points of approach CPA for the containership sample were significantly larger than for the VLCCs, even though larger course changes were made by the VLCCs at approximately the same range 4 nm.
