Risk Based Asset Management - Delivering and Sustaining Value Across a Mid-Sized Refining Enterprise (RMC-09-45)

The key to sustaining the value from a reliability-based mechanical integrity (RBMI) program begins with program ownership and continues with best practice management systems. We began our RBMI program with a pilot study in 2005 at one of our refineries. The pilot involved migrating our time-based fixed equipment inspection program to a RBMI program for eight process units. The study cost approximately $400,000 and was completed in less than four months. The return on that investment yielded a payback in less than twelve months and a value that exceeded $2.5 million in turnaround cost savings and quickly delivered almost seven million dollars in risk reduction.
