Abstract: Since the Jane Typhoon in 1950, which induced much damages on port and harbour facilities and the ships in the ports, it has been a custom in Japan that the large-sized ships take refuge outside the port under the stormy weather such as typhoon. This outside-harbour-refuge results in much economical loss for the ships as well as the port operator. The inside-harbour-refuge is again focused recently. However captains are very much anxious about the present safety level of the inside-harbour-refuge. The captains' risk aversive tendency should be taken into consideration in planning and design of the port and harbour facilities. The present paper discusses the captains' decision criteria for the refuge action under stormy weather, and proposes a method of the safety improvement planning of port and harbour facilities based on risk-cost-benefit analysis.
