Primatech PHA-Works is a mature, desktop-based software solution specialized for Process Hazard Analysis (PHA), with robust support for HAZOP studies and other techniques like What-If, FMEA, and LOPA. It provides structured worksheets for documenting deviations, causes, consequences, safeguards, and recommendations, facilitating collaborative team sessions. The tool excels in generating detailed reports, risk matrices, and exports for compliance and follow-up actions in process industries.

DNV Synergi Plant is a comprehensive engineering software suite designed for the design, operation, and maintenance of process plants in industries like oil & gas, chemicals, and power. It includes dedicated HAZOP modules for conducting structured hazard and operability studies, supporting digital P&IDs, node-based analysis, and risk assessment workflows. The tool integrates HAZOP with other analyses such as SIL verification, LOPA, and bowtie diagrams for holistic safety management.

BowTieXP is a specialized software tool from CGE Risk Management Solutions designed primarily for creating interactive bowtie diagrams to model risks, hazards, threats, consequences, and control barriers. While not a traditional HAZOP worksheet tool, it supports risk identification and analysis through visual bowtie methodology, which can complement HAZOP studies by providing a graphical representation of deviations and safeguards. It excels in barrier management, auditing, and enterprise-level risk visualization for high-hazard industries like oil & gas and chemicals.

exSILentia, available from erm.com (now part of DNV/Sphera ecosystem), is a process safety lifecycle software primarily focused on Safety Integrity Level (SIL) verification but with robust support for HAZOP studies, LOPA, and risk graphing. It enables teams to import HAZOP worksheets, link safeguards to SIL calculations, and generate comprehensive reports for regulatory compliance in process industries. While not a pure HAZOP tool, it excels in integrating hazard identification data into quantitative risk assessments.

FaultTree+ from Isograph is a specialized software for fault tree analysis (FTA), event tree analysis, and related reliability modeling, often used in safety and risk assessment workflows that complement HAZOP studies. It allows users to graphically construct fault trees, perform probabilistic calculations, and identify critical failure paths through cut-set analysis. While not a primary HAZOP tool with native worksheet or guide-word templates, it excels in quantitative follow-up analysis after qualitative HAZOP sessions, integrating with Isograph's broader Reliability Workbench suite.

ReliaSoft XFMEA is a reliability engineering software suite that supports HAZOP studies as one of its core analysis methods, alongside FMEA, FMECA, and RCM. It provides structured worksheets for hazard identification, deviation analysis using standard guide words, and risk prioritization in process safety assessments. Designed for integration with other ReliaSoft tools like Weibull++ and BlockSim, it enables data-driven reliability predictions and reporting for complex systems.

Intelex PHA is a cloud-based Process Hazard Analysis software module within the Intelex EHSQ platform, designed specifically for conducting HAZOP studies, LOPA, What-If analyses, and other PHA methodologies. It provides customizable worksheets, guideword libraries, risk matrices, and collaborative tools to document hazards, causes, consequences, and safeguards efficiently. The software emphasizes audit trails, automated reporting, and integration with broader EHS management systems for enterprise-wide risk oversight.

Cority PHA is a specialized module within the Cority EHS management platform, designed for conducting Process Hazard Analyses (PHA) including HAZOP studies in high-risk industries like chemicals, oil & gas, and manufacturing. It provides structured worksheets for identifying deviations, causes, consequences, safeguards, and risk rankings, while supporting team collaboration and action tracking. The software integrates with broader EHS workflows for compliance reporting, audits, and continuous improvement.

OmegaLand HAZOP, developed by Hitachi High-Tech, is a specialized software tool for conducting Hazard and Operability (HAZOP) studies in process industries, supporting structured risk assessments through guideword-based deviation analysis. It enables collaborative team sessions, cause-consequence linking, and automated report generation, with integration into the broader OmegaLand suite for plant lifecycle management. Primarily targeted at engineering firms handling complex industrial plants, it emphasizes compliance with standards like IEC 61882.
