Keep your facility safe and compliant — don’t let your PHA become a “check-the-box” task. Regular, well-executed PHA revalidations identify evolving risks and turn findings into action, ensuring lasting protection for your people, assets, and operations.

Learn how FSA Stage 2 ensures your Safety Instrumented System (SIS) is ready for field installation, preventing rework & project delays.

Verify your Safety Instrumented System's readiness with a Stage 3 FSA, ensuring safe operation and compliance with design specifications.

Discover how a Stage 1 FSA can identify critical Safety Instrumented System (SIS) flaws early in the design process.

Updated April 2026 - We can help you pick up your PHA/LOPA which maybe been put to the side and provide the services to set you up for the safety system design phase. Standard SIS deliverables include the review of specification, confirming that the SIL levels are what they should be, and that the proof testing procedures are correctly documented to support your regular testing intervals.  Transcript: "aeSolutions has a full suite of offerings and the safety lifecycle, from

Updated April 2026 - A Functional Safety Assessment (FSA) is defined by the IEC 61511 standard as an “investigation, based on evidence, to judge the functional safety achieved by one or more SIS and/or other protection layers.” The ultimate goal of an FSA is to make the team confident that their instrumented safety system will reliably achieve the risk reduction needed. While many organizations understand the importance of FSAs, not everyone realizes the significant advanta

The 2nd edition of IEC 61511 now requires – by use of the word “shall” – that a Stage 4 Functional Safety Assessment (FSA) be conducted...

Key considerations to developing SIS guidelines, with the SIS lifecycle generalized into three main sections: Concept Through Startup, Opera

What’s a HIPPS and where are they used? Updated April 2026 - There are two common applications for a High Integrity Pressure Protection System (HIPPS) . First, many process facilities have expanded to the point where the original pressure relieving and flare system may no longer be able to handle a potential event. Preventing a potential overpressure through the use of a HIPPS can be done at a much lower cost compared to installing a new flare and header system. Second, many
