Failure Rate Analysis Paralysis
Reliability Engineering experts know there are many variables that impact operational failure rates. These variables even include how operations and maintenance are done at a specific site. Sometimes it feels like there are so many variables that no realistic failure rate can ever be predicted without a few hundred hours of…

Is Your SIS as Reliable as You Think? The Hidden Risk of “Run-to-Fail”
This is a subject and problem that often comes up when discussing SIS and especially with legacy systems. Given today’s modern instrumentation and the improvements in reliability, some people argue that there’s no need to replace the equipment until it fails. This certainly could be said for Basic Process…

Two Billion Hours
When I studied Reliability Engineering in graduate school, I was taught that failure rate data came from field failure studies. I assumed that operating companies always kept accurate records when a piece of equipment failed. I also assumed that someone would investigate the failures and assign a root cause.…
