In Japanese industries of domestic marine transportation, a steady decrease in aspiring sailors, especially young sailors, and their aging tend to become a serious problem that the reduction of skilled operators might affect total transport volume and safety navigation near future. For the settlement of this problem and the reduction in transportation cost, the ship modernization is going to be developed the means, that are composed of the improvement of working environment, the decrease in ship operator load and the realization of safety navigation with few operators, by several organizations. Accordingly, the redundancy system for safe navigation and cargo management be aimed at the development of functional devices ensuring safety and reliability. Moreover, the methodology of system design for the safe navigation system and reliable cargo handling system, consisted of reliability on hardware and human factors, should be desirably instituted by grasping the personnel behavior based on the associated in simulated operation and investigation of human errors. A methodology of ensuring safety and reliability for the design of ship modernizing system is described in this paper. Further, An estimation method on the probability of human error and the frequency of device in the functional system is proposed by using an apprehensive degree, which is defined as similar to the sense scale based on the experience of skilled ship operators. As a practical example, the reliability analysis on automatic cargo handling system developing newly are carried out using our proposed method.
