Abstract:
Asset management through operational reliability has been a theme for achieving better asset value for a facility. In the case of pelletizing, there is a lack of literature describing the use of operational reliability indicators. This paper evaluates, through indicators and results obtained, the implementation of the operational reliability process at Vale Tubarão pelletizing plant. The main indicators were: downtime, loss time and the number of events related to the operation. The study found that, after the implementation of reliability, there was a decrease in downtime and losses in the A, C and E mills. Other plants were operationally impacted with the occurrence of single events. The implementation of operational reliability allowed for the proper treatment of critical and routine failures, especially recurrent ones, leading to a reduction in the number of failures. The process risks were treated and minimized from the structuring of the reliability routine.
