TWI's RISKWISET RBI software was recently applied at Nippon Mitsubishi Oil Company's (NMOC) Negishi Refinery, Japan's largest oil refinery in Yokohama.
The results of the NMOC study demonstrated the potential for incremental run length extension after selected equipment modifications. It also highlighted the scope for reduced shutdown inspection effort on a significant number of items, as well as suitable and cost-effective risk mitigation actions.
A senior NMOC spokesperson commented: "The software is very easy to use, so special training is not required. It enabled us to demonstrate the integrity of our plant using an advanced maintenance system. RISKWISET addresses not just those damage mechanisms known to be dominant in causing failure but also other damage mechanisms which may become active."
