Top 10 Root Causes for Fixed Equipment MechanicalIntegrity Failures - Part 1By John Reynolds of Inspectioneering.com
RL Blogs
The first part of a two part series that assesses the top ten reasons for FEMI failuresthat cause process safety incidents.
Fixed equipment mechanical integrity(FEMI) failures are not caused bydamage mechanisms; rather, they'recaused due to failure to create,implement, and maintain adequatemanagement systems to avoid failures.
Nearly all failures that have occurred inour industry could have been avoided if these human systems were morerobust and sustainable in providing theprimary layers of protection for FEMI.
The ten reasons I’ve outlined are a result of doing 60+ FEMI audits withinrefineries and chemical plants in the last 45+ years, tracking 150+ seriousFEMI incidents in the petroleum and petrochemical industry and theircauses, and defending numerous clients in the industry from lawsuitspertaining to FEMI issues. Before we jump into the first five reasons, let's start with a few quick notes:
Throughout these posts, I'll be using the acronym FEMI, whichstands for fixed equipment mechanical integrity . You might alsoknow it as pressure equipment integrity management.
This blog is an abridged version of an article that is coming up in anissue of Inspectioneering Journal. If you haven't subscribed yet, doso here so you won't miss the full version of this blog series.
I presented this topic at the upcoming ASME Pressure Vessel andPiping (PVP) conference this year in July Anaheim, California.

already has all of those programs." My point isn't that it is the existence of each of these FEMI programs that is most important, but rather the qualityand sustainability of them. If each operating site wants to largelyeliminate the risk of a big FEMI event at their site, then each operating sitemust obtain and sustain an "A" grade on each of these top ten FEMI issues;a score of less than that will generally not suffice. Each site needs to achieve excellence in implementation . Not justcompliance, and not just "checking the box" because of some rules and
regulations. Excellence simply means doing all the right things, and doingthem right each and every time in accordance with an up-to-date,documented FEMI management system. Now, let's briefly mention the first five of ten reasons for significant fixedequipment mechanical integrity failures in the hydrocarbon process industry.
Reason #1: Inadequate or lack of identifying and managing thehighest priority FEMI risks in each process unit
Each process unit should keep a list of the highest FEMI risks at each site--not just a FEMI bad actors list--there's a significant difference between themwhich will be explained in a future article in the Journal. The highest FEMI risk list should be prioritized with all other site resourcedemands and kept in front of all key stakeholders at the site. We need tohelp all stakeholders understand that even though most equipment damagemechanisms result in leaks with minor consequences, every once in a whilethey have huge process safety consequences such as fires, explosions,injuries, fatalities, adverse media attention, fines, lawsuits, and a threat tocontinued operations. Does your site track and mitigate its highest risk FEMI issues in each processunit?
Reason #2: Inadequate or lack of comprehensive Corrosion ControlDocuments (CCD's) for each process unit CCD's take the generic damage mechanisms found in API RP 571 and makethem specific to each process unit at each site. They capture nearlyeverything that is known about how equipment degrades in a particular fluidservice, under specific process conditions, and how to find it, avoid it, and
mitigate it. CCD's, when created properly, become the primary source of knowledge transfer to all other stakeholders in the site. I should mention that API RP 970, currently in progress of being written, willoutline the entire work process to produce a comprehensive CCD. Does your site have complete, detailed CCD's that capture everything that isknown about the potential for FEMI failures in each of your process units?
Reason #3: Inadequate or lack of a thorough, comprehensive pipinginspection program per industry standards

process engineering know what changes should be assessed with theMOC process.
Too many sites don't communicate well with the FEMI group onabnormal or upset conditions that may lead to accelerated corrosionand unanticipated damage mechanisms.
Some process and operating personnel don't understand thatinspection schedules and strategies are based on historic records
and that inspectors are not just constantly looking for new orunexpected corrosion.
Is your MOC process as effective on process changes as it is on physical changes?
At this point, I’ve outlined the first five of ten reasons for fixed equipmentmechanical integrity failures in the hydrocarbon process industry. I’ll followthis article up with another one that contains the remaining five reasons,which are:
Inadequate implementation of guidance from industry codes andstandardsInadequate programs for learning from previous FEMI incidentsInadequate record-keeping and data analysisNot using the best available NDE and inspection technologyInsufficient training and knowledge transfer for FEMI personnel
