Making Safety Simple

aeShield is making safety simple by executing, monitoring, and sustain the process safety lifecycle as defined by ISA-84 / IEC 61511. So, what do we mean when we say:


“Execute” is the generation of compliance documentation, such as a PHA Report, LOPA Report, and a Safety Requirement Specification. This documentation represents the foundation of your overall functional safety health. aeShield comes equipped with tools to help generate this information as quickly and objectively as possible whether in Greenfield or brownfield environments. For example, review “Capital Project Execution” on our website to learn more about templates and equipment under control. The tooling makes it simple to manage resources, migrate legacy data as needed, and bulk insert from other tools such and equipment databases.

Many folks believe having this documentation in place implies compliance with the standards. Unfortunately, execute represents a snapshot in time and the documentation alone is not making your facility safer on a daily basis. aeShield was built to execute compliance documentation as cost effectively as possible, but also enables monitoring…

“Monitor” is the validation that assumptions made during the execute phase are accurate. Traditionally, synchronizing massive flat file reports with operational data has been extremely tedious.
(See Figure 1)

aeShield contains agnostic interfacing to maintenance management systems and process historians. These connections allow you to:

  • Track demands
  • Aggregate time in bypass
  • Monitor test intervals
  • Monitor and classify failures

and more to ultimately understand where you have bad actors in the form of poor assumptions or faulty equipment. (See Figure 2) Once you can make the previously invisible visible, you can begin to sustain your business.

Figure 2 - Monitoring Events from Operational Data

“Sustain” is the identification of bad actors through monitoring and taking action to remove risk from the business. The bad actors increase the likelihood of a loss of containment event.

In addition, the bad actor may prove to be performing in an overly conservative manner. Therefore, realign your resources that are focusing on over protected scenarios to address gaps.

aeShield contains a health meter the pinpoints bad actors and eventually will generate a Functional Safety Index™ (FSI). To learn more about FSI, watch our video or read a recent whitepaper on this single metric that encompasses the overall health of your facility. Armed with this simple metric, you can help educate your management on functional safety and effectively compete for limited capitol.
