Home Health Case Studies in Maintenance and Reliability: A Wealth of Best Practices
Practicing Oil Analysis Magazine. July 2001.
If the motor is offset misaligned by 10 percent of the coupling manufacturer's allowable offset, then one can expect a 10 percent reduction
in inboard bearing life.

Location: 2.2.2Large Complex Oil Refinery in the Far East
A recent benchmarking study and follow-up review revealed that our reliability was poor. The overall Mean Time Between Failure (MTBF) of rotating equipment in our refinery was about ten or eleven months. Locations with high reliability were getting an MTBF of about four or five years, so we had a long way to go. The Engineering Manager tried to address this issue, but previous attempts ended in failure. This time he was determined to succeed, so he gave me the job of identifying the issues and putting together a strategy to bring top performance.
I chatted with a number of people in the location as I don't find formal interviews very effective. These chats threw up a number of interesting comments:
Based on these findings we agreed on a multi-pronged approach to pump reliability improvement and a framework for action. What we wanted to achieve is well captured in Ron Moore's words, "Fixed forever as opposed to fixing forever."
