The maintenance management of static storage equipment in terminals and refineries is challenging when you need to plan the schedule of shutdown for cleaning and preventative maintenance on the tank park, especially when the stored fluid contains particles that settle on the bottom. In most cases, the actual volume of sediment is usually unknown, it is not uniformly distributed at the bottom and the real impact is only revealed during the cleaning operation, entailing the risk of opening a less dirty tank instead of the one in more critical situation. Also there is the risk of hiring fewer resources than necessary for the cleaning operation and waste treatment, or the opposite situation. If the annual results of maintenance costs in a terminal or refinery with a large number of tanks could be evaluated, these inconsistencies, that are possible to occur, would generate additional unforeseen costs or hiring more resources than necessary. These impacts would be distributed in the tank downtime, cost of work-hours in various hierarchical levels, various third party services, supply management, etc.
