When an asset is operated in variable conditions, its operational efficiency can be improved significantly when the maintenance is performed in a dynamic manner. This means that variations in usage and operating environment are taken into account when deciding on the length of the maintenance intervals. Several predictive maintenance strategies, that enable such an approach, are nowadays being developed. However, demonstrating the benefits of these new maintenance concepts is generally difficult. As a result, implementation of the concepts is still rather limited. In this paper, a previously proposed modeling framework is used to quantify the performance of different maintenance policies for a navy frigate. A corrective policy will be used as a reference situation. Then the performance of a calendar time based, usage severity based and condition based maintenance policy will be calculated and compared to the reference policy. In all cases the performance of the policies is quantified through the total maintenance costs and the achieved system availability.
