Case Study on the Unavailability of a Ship Propulsion System under Aging Effects and Maintenance
1 Tokyo University of Marine Science and Technology, Tokyo, Japan
ABSTRACT: Unavailability of a ship propulsion system under aging effects and proper maintenance is estimated using GO-FLOW. GO-FLOW is an effective software tool for the unavailability analysis of complex systems. Aging effects are incorporated into GO-FLOW using a time-dependent technique and assuming a linear aging model. The results show that the aging effects and improper maintenance can potentially increase the frequency of accidents due to a malfunction of the propulsion system by a factor of three.
