Abstract
Many machines including marine diesel engines and plants are operated while maintaining their functions and safety through inspection and maintenance. At the present time, time-based inspection and maintenance practices are generally adopted. However, a more effective inspection and maintenance scheme that reflects the present economic situation is required. As such, a risk-based inspection/maintenance (RBI/RBM) technique for electric power plants is introduced. This technique is regarded as an efficient method of maintaining machine and plant safety within the limits of cost and manpower. On the other hand, RBI/RBM has not yet been applied to marine diesel engines. To apply RBI/RBM to a marine diesel engine, risk evaluation should be conducted first. In this paper, risk evaluation of a marine diesel engine was performed based on a database of ship failure.
