The data reported in this paper provide documentation of the performance of deck officers using both basic radar equipment and automated collision avoidance systems. As a part of a continuing Maritime Administration study directed toward the design of a standardized bridge, comparative performance and workload were evaluated over several months aboard vessels of different types operating over several trade routes. Some of the conclusions reached with regard to the use of automated collision avoidance systems include: (1) the range at which approaching ships are detected as threats was doubled, (2) the closest point of approach resulting from evasive maneuvering was doubled, (3) the deck officer's workload was reduced by factors of two to four depending upon the situation, (4) saturation workloads for officer in critical maneuvering situations were eliminated, (5) difficult analytical tasks were replaced by short duration detection tasks, and (6) no deterioration either in the deck officer's vigilance of in his use of readily discernible course changes was noted. Use of automation equipment which complements rather than replaces operating personnel appears to contribute to both the safety and efficiency of ship operations in the case of collision avoidance equipment. This concept may be applicable to other areas of ship operations.
