The Challenge: HAZOPs Drained Valuable SME Capacity
As required by OSHA, a mid-sized North American chemical producer conducted Hazard & Operability (HAZOP) studies for each unit in the plant on a 5-year frequency. But with 10 process areas and a continually shrinking pool of SMEs to pull in, HAZOP workshops were a major draw on the site’s most experienced personnel.
Every revalidation cycle required process engineers, operators, EHS leaders, and maintenance experts to spend weeks walking through every deviation-guideword row, often searching for missing information or rebuilding process context rather than evaluating risk. The site was seeing a downward trend in key business metrics like product quality, downtime, and maintenance cost. The people they counted on to improve these metrics were trapped in a conference room highlighting P&IDs.
The Solution: Auto-generated HAZOP Drafts Built on Plant Documentation & Expertise
To reduce the preparation burden on SMEs, the company deployed UptimeAI’s HAZOP Analysis Agent to automate the most time-intensive portions of the PHA process. Starting from existing P&IDs, the agent automatically identified equipment, instrumentation, and process flows to build a digital representation of each unit. The agent generated draft HAZOP nodes, organized relevant documentation, and produced initial deviations, causes, consequences, safeguards, and recommendations aligned to the company’s risk framework.
Rather than starting from a blank worksheet, SMEs entered workshops with a fully populated draft analysis already in place. This shifted their role from manually assembling information to validating risk scenarios, refining recommendations, and making higher-value operational decisions.
The Impact: More Time Spent Managing Risk, Less Time Preparing for Reviews
By deploying the HAZOP Analysis Agent, the site significantly reduced the operational burden associated with recurring PHAs.
Results That Scale
After successfully demonstrating the impact of HAZOP Analysis Agent on SME time for one process unit, the site rapidly expanded to include all site process units + sitewide deployments for all other plants under this business unit. The sites are leveraging the unlocked SME capacity for improvement projects targeting process efficiency, reliability, and quality metrics, while the process safety incident rate is at the lowest it has been in the last decade.
