Aiming at realization of safer and more effective marine transportation, a national project of a highway network on sea surface has been progressed in Japan. A high-speed transportation in congested sea area is one of the key items to be realized in the project. As each high-speed craft has its peculiar configuration and mission, safety assessment of its navigation should be evaluated taking traffic condition, craft performance, navigation aids and human operators corresponding to each craft into account. A procedure of the safety assessment based on ship handling simulator experiments is proposed. The effectiveness of the procedure has been confirmed by applying to a large hi-speed craft navigating in Tokyo Bay as one of the most severe congested conditions. The procedure comprises suitable modeling and installation to the simulator, adoption of the typical and most difficult scenarios and combination of expert mariners' subjective evaluation and objective evaluation with appropriate indices. A safety margin based on OZT(Obstacle Zone by Targets) is also proposed as an appropriate index for objective evaluation of high speed navigation in congested sea area. A comprehensive safety assessment procedure is proposed based on the research results.
