Abstract
Generally, in-depth knowledge is required of all huge plant operators in order to continuously keep the plant in a good condition. Ship engineers have the same work as huge plant operators except for the conditions of self-reliance and self-sufficiency at sea. On the basis of the cognitive process of human activities, Rasmussen proposed three different modes, such as the knowledge-based mode, the rule-based mode, and the skill-based mode. An important but complex feature is to understand how to accomplish the plant operator shift between each mode. In this paper, the authors focus on improving the proficiency of ship engineers. Some experiments were carried out on the training ship of the National Institute for Sea Training, Japan.
