Our engineering team facilitate and document Process Hazards Analysis (PHA) in accordance with the ISA/IEC 61511 Functional Safety – Safety Instrumented Systems for the Process Industry Sector and OSHA Process Safety Management (PSM) Standard 29 CFR 1910.119 standards. Experienced in chemical process, control systems, and the standards, our members can facilitate HAZOP, LOPA, HAZID, Security PHA Reviews, and other studies including documentation.

Process Hazards Analysis (PHA)

Process Hazards Analysis (PHA) — including a full range of facilitated/workshop studies like HAZOP, LOPA, HAZID, and a full-range of auditing.

PHA studies are easily documented and audited in Open PHA™ HAZOP/LOPA Documentation Software, and Open Audit™ Documentation Software.

Hazardous and Operability Studies (HAZOP)

Hazard and Operability (HAZOP) studies provide recommendations based on causes and consequences that require further attention.

Layer of Protection Analysis (LOPA) & Quantitative Results Analysis (QRA)

Layer of Protection Analysis (LOPA) is commonly used to assess the risk of the areas identified in the HAZOP to determine the target Safety Integrity Level (SIL) required to reduce the risk to an acceptable level. LOPA uses semi-quantitative techniques to deal with probabilities.

Complex scenarios are analyzed using Quantitative Results Analysis (QRA) potentially in a fault-tree tool like Arbor™.

LOPA studies are easily documented in software tools today like OpenPHA™.

Security PHA Review

Security PHA Review -was developed by Kenexis and is a disciplined approach to reviewing a PHA, especially a HAZOP, for cybersecurity threat vectors that have consequences.

You can read more about in our Post or get the book at Security PHA Review.

Continuing Engineering Support

Continuing Engineering Support provides either a service or seconded (contract) employee. Companies can take advantage of contracting an SIS or PSM expert with the backing of Kenexis for extended periods to function as part of an engineering team. Or companies can take advantage of the same Kenexis staff  to function as a service to provide the same functions as an independent third party.

In either role, Kenexis staff serves as an advocate of the safety control, alarms, and interlocks (SCAI) asset base for the client (including safety instrumented system (SIS), fire and gas detection systems, and critical alarms). The position works cross-functionally to advocate for best practices in the selection, implementation, and maintenance of the SCAI asset base to ensure that regulatory, production, and optimization objectives are met.
