FMECA in process safety - Failure Mode Effects and Criticality Analysis

FMECA in Process Safety: A Comprehensive Guide for Engineers and Safety Professionals

If you work in a plant that handles hazardous chemicals, you already know this truth: Equipment never just “fails”. It fails in a specific way, for a specific reason, and that failure has a specific impact. Failure Mode, Effects and Criticality Analysis (FMECA) is a structured way to map all of that out before something...

QRA for Whom?

Summary: This article explains how Quantitative Risk Assessment (QRA) serves different stakeholders—not just as a compliance tool, but as a practical decision engine. It shows how to tailor QRA outputs for executives, project teams, PSM and operations, regulators, insurers, emergency planners, investors, and communities using tools like IR contours, F-N curves, and more. Quantitative Risk...

FPSO Safety: The Role of PSM

Summary: This article breaks down how to make FPSOs safer by treating process, marine, and storage/offloading risks as one system. Starting from MAHs and bow-ties, we show how to set SCEs that cover cargo tanks and inerting, turret/moorings, risers, DP/drive-off, and shuttle-tanker SIMOPS. We outline practical MOC/SIMOPS controls, proof of barrier health via testing,...

What is QRA (Quantitative Risk Assessment) in Process Safety & Why It Matters in High-Hazard Industries: A Quick Guide

Summary: Quantitative Risk Assessment (QRA) is a structured, data-driven method that estimates how often hazardous events could happen and how severe their consequences could be. By combining frequency analysis with consequence modeling, QRA quantifies individual and societal risk to guide ALARP decisions, safeguard design, emergency planning, and regulatory compliance.

Recent Process Safety Incidents that Likely would have been Prevented with Proper HAZID

Summary: Some of the recent oil, gas, LNG, and chemical incidents highlight how weak hazard identification can escalate into major losses. Investigations reveal recurring gaps: underestimated process deviations, overlooked human–machine interactions, and poor recognition of cascading failures. Missed barriers—such as inadequate relief systems, flawed alarm management, and incomplete safeguards—left operations vulnerable. Root causes often trace...

How to Conduct Hazard Identification Study for High-Hazard Industries (Oil & Gas, Chemical, CCS, Hydrogen)

Summary: Before risks become realities, they exist as overlooked details in design and operation. A Hazard Identification (HAZID) study is not just a checklist—it’s a focused inquiry into how things might go wrong and what that truly means. This blog breaks down the HAZID process into its core mechanics: from defining intent and applying ISO...
