Study on the Human Error by Unskilled Trainee in Marine Engine Plant Operation

摘要

This paper, for the purpose of machinery plant operation training by means of Engine Room Simulator (ERS) based on PC, describes the features of human errors by the unskilled trainees in the marine engine plant operation and shows the necessary improvement in the training in order to decrease such errors from the viewpoint of educational technology. Human error data were collected out of the simulator operation record and observation of the trainees in VTMARU (Vietnam Maritime University). The examination of such data has shown that error occurs mainly by omission error and extraneous act. Further analysis was made on such errors by the trainees to find out the characteristics of errors caused in the process of acquiring procedural knowledge for the operation. The analysis has revealed that the human errors occur for the following reasons: (1) Lack of knowledge on the over all system and fundamental operation; (2) Insufficient confirmation to operation; (3) Incomplete knowledge on the operational sequence. In this paper, the roles of instructor will be described in order to reduce the cause for such human errors and to enhance the educational performance.
