Reynolds Wrap Up: API Publishes Helpful Guide on Fixed Equipment Mechanical Integrity (FEMI) Standards

By John Reynolds at Intertek. February 27, 2018

The Subgroup on Mechanical Integrity (MISG) was formed as part of the Advancing Process Safety (APS) initiative between the API and AFPM to improve process safety in the hydrocarbon process industries.  This group, which consists of owner-user FEMI representatives from API & AFPM member companies, was formed with the recognition that leaks and failures from piping and equipment were due at times to MI and inspection issues.  The MISG is focused on improving FEMI standards and practices to advance process safety while other APS initiatives focus on the other key elements affecting process safety, though all subgroups are highly integrated. 

Annually, each Subgroup sets goals to improve process safety in their focus area.  The Subgroups report their progress to the Process Safety Advisory Group (PSAG) which consists of executive members from the API & AFPM member companies.  In 2017, one of the major MISG goals was to produce a brochure that summarized all the key API standards that dealt with FEMI that industry sites can/should be using to improve their FEMI programs and hence prevent leaks and failures in equipment and piping. 

The brochure is now available on the website  It describes the latest edition of 42 API standards addressing FEMI issues, including fabrication, construction, in-service inspection, engineering evaluation, maintenance and repair of fixed equipment and piping, as well as various materials, corrosion, and welding issues that affect FEMI.  It also contains an interesting historical chart listing when the first edition of each of the standards was published, starting with API RP 520 in 1955, as well as API 510 in 1958.  It shows that the API has significantly ramped up its production of FEMI standards since the turn of the century by publishing 21 new and revised standards since the year 2000. 

Hence, it’s vitally important that all users of these 42 FEMI standards obtain and implement the latest edition of each. The latest editions recognize many new and improved FEMI technologies and methodologies that sites can/should be using as recognized and generally acceptable good engineering practices (RAGAGEP). 

If you would like to join  our efforts to continue to update and improve these FEMI standards, please join us at our next API Subcommittee on Mechanical Integrity and Inspection (SCIMI) meeting in conjunction with the 2018 Spring Refining and Equipment Standards Meeting in Seattle, April 16-19 at the Seattle Sheraton.  Visitors with expertise and experience in FEMI are always welcome.
