A new standard, ISA 84.91.03, builds upon guidelines published in the CCPS LOPA, CCPS IPS, CCPS IE/IPL, and CCPS Safe Automation books, codifying them into a standard enforceable under process safety management regulations. Since the term BPCS is often confused with the control system, the new standard uses the term low-integrity protection layer (LI-PL) to cover any instrumented protection layer that is not expected to provide performance equivalent to a SIS but is needed to provide risk reduction. This new standard will significantly impact current industry practices, from identifying LI-PL during the process hazards analysis to monitoring their installed performance.  This webinar will provide an overview of ISA 84.91.03 to raise awareness of the new standard's requirements and discuss its impact on typical process industry practices. 

Are your risk assessment teams aware of key differences between performing a Process Hazards Analysis (PHA) and a Hazards and Risk Assessment (H&RA)? How about the gap between safeguards and protection layers? With nearly 35 years of industry experience, Eloise shares some key distinctions between these methodologies and highlights potential complications in instrumented protective system (IPS) identification that can cost your projects precious time and money if they are not avoided.

API Recommended Practice 551, Process Measurement, covers design and installation guidance for pressure, temperature, level, and flow measurement technologies.   The 3rd edition is expected to be published toward the end of 2025.  Melissa Westbrook, Senior Consultant and SIS-TECH's representative on the API 551 committee, provides an overview of the upcoming changes.

The 3rd edition includes changes to the level technology and temperature measurement sections, such as expanded technical coverage of nuclear level systems, design requirements for protection tubes, testing recommendations for thermowell, and multipoint temperature measurement system design features.  

The instrument installation section has been updated to expand guidance for pressure measurement mounting practices and provides installation strategies to minimize vibration and thermal effects.

The updated document will include a new section that discusses instrument inspection before system commissioning.  This new section will include general instrument infrastructure inspection - such as tubing inspection and leak testing procedures - and recommended inspection scope for the different types of level, temperature, pressure, and flow instrumentation technologies. 

This webinar introduces the new features of SIL Solver Enterprise+ V2.6!

SSE+ V2.6 supports the different roles and responsibilities of personnel supporting the safety lifecycle, allowing you to control who can view or edit system data and who can add to or modify corporate-wide metadata.

SSE+ V2.6 covers the documentation requirements of IEC 61511 for safety instrumented systems and the impending requirements of ISA 84.91.03 for instrumented protection layers, such as safety interlocks, BPCS, IPL, Fire and Gas, ESD, and equipment protection.  

Key capabilities of SSE+ V2.6 include scope and hazard registries, document registry, Functional Safety Assessment (FSA), audits, process requirements specification, SIL verification, Safety Requirements Specification, Application Program Specification, and I/O lists.
