Abstract

Maintenance tasks and applications in the shipping industry have evolved significantly in the last few years. Particularly in the offshore industry, safety inboard, environmental protection and intensive operational activities necessitate the minimisation of down-time and the preservation of an excellent performance ratio. The research study herein presents a review of the maintenance standards and procedures together with an enhanced ship maintenance approach based on criticality and reliability assessment. Fault Tree Analysis (FTA) with time-dependant dynamic gates is used to represent the interrelation of the system’s components. Moreover, the Birnbaum and Criticality reliability importance measures validate the results of the analysis. A case study of a diving support vessel will illustrate the application of this approach. Main outcomes are the identification of the critical items of each system as well as suggest measures which will enhance the operational availability and capability of the vessel.
