The need to improve maintenance strategies and reliability
In an effort to improve its maintenance strategies and improve reliability, Vale implemented Predix Asset Performance Management (Predix APM) (formerly Meridium Enterprise APM), specifically including the APM Reliability and APM Integrity solutions. These solutions included production analysis, thickness monitoring, and root cause analyses (RCA) capabilities.
Vale partnered with the Predix APM team to perform an RCA audit to analyze the condenser system and document failures, as well as develop strategies to prevent reoccurrence. Before the analysis of the condenser system was performed, its function was unknown and the weak acid flow was under the defined limit. The problem signified a larger challenge that the company needed more than a maintenance fix and required a cultural change to fully embrace and practice ongoing reliability efforts.
