What If We Had Never Performed a HAZOP Study
Imagine commissioning a process plant without systematically asking what could happen if pressure rises unexpectedly, flow stops, temperature falls outside its intended range, or an operator takes an incorrect action. The facility may operate normally for months or even years. But normal operation does not prove that every credible deviation has been identified or that […]
What Is a SIL Assessment, and Why Is It Important for Process Safety?
Industrial facilities use multiple safeguards to prevent hazardous process conditions from escalating into serious incidents. Where instrumented protection is required, a Safety Instrumented System (SIS) can automatically move the process toward a safe state when predefined conditions are detected. But how reliable does that protection need to be? A SIL assessment, or Safety Integrity Level […]
Preliminary Hazard Analysis (PHA)
Identify potential hazards early, prioritize significant risks, and support safer engineering and project decisions before risks become more difficult to manage. Aura Safety & Risk Consultants provides Preliminary Hazard Analysis (PHA) for industrial facilities and projects as part of its process safety services. The study provides an early, structured view of potential hazards and their […]
Process Hazard Analysis (PHA): Methods, Steps & Importance in Process Safety
Process industries routinely handle hazardous chemicals, pressure, temperature, stored energy and complex operating conditions. A failure in equipment, controls, procedures or human interaction can develop into a serious process safety incident. Process Hazard Analysis (PHA) provides a structured way to identify these hazards, understand credible accident scenarios and evaluate whether existing safeguards adequately control the […]
Green Hydrogen Safety: Understanding Hazards and Managing Risks
Green hydrogen is becoming an important part of the transition toward lower-carbon industrial and energy systems. It is generally produced by using electricity from renewable sources to split water through electrolysis, creating hydrogen and oxygen. From a sustainability perspective, this creates significant opportunities. From a process safety perspective, however, hydrogen requires careful attention throughout production, […]
HAZOP Study for LNG Facility: Identifying Process Hazards Before They Escalate
Liquefied Natural Gas (LNG) facilities involve cryogenic conditions, flammable hydrocarbons, complex process equipment, storage systems and transfer operations. A deviation in pressure, temperature, flow, level or operating sequence can create conditions that require careful evaluation before they develop into a significant process safety event. A Hazard and Operability Study (HAZOP) provides a structured method for […]
When and Why Process Industries Should Conduct a 5-Year HAZOP Revalidation
A HAZOP study captures the hazards and operability concerns identified using the process information and operating assumptions available at the time of the study. But an operating plant rarely remains unchanged for years. Equipment is replaced. Production rates change. Control systems are modified. New chemicals may be introduced. Operating procedures evolve. Temporary modifications can become […]
How to Divide a Plant into HAZOP Nodes
A HAZOP study guide does not normally examine an entire process plant as one large system. The process is divided into smaller, manageable sections called HAZOP nodes, and each node is systematically reviewed for deviations from its intended operation. Selecting those nodes correctly is an important part of preparing an effective HAZOP. If nodes are […]
HAZOP Guidewords & Parameters: A Practical Guide to Identifying Process Deviations
A Hazard and Operability Study (HAZOP) is a structured method used to examine how a process can deviate from its intended design or operating conditions. One of the most important parts of this methodology is the systematic use of HAZOP guidewords and process parameters. Guidewords such as No, More, Less, Reverse, Other Than, As Well […]
Top 10 HAZOP Mistakes That Can Lead to Major Accidents
A Hazard and Operability Study (HAZOP) is intended to systematically examine a process or operation, identify credible deviations from design intent, evaluate their potential causes and consequences, and review the safeguards available to control the associated risks. But completing a HAZOP does not automatically mean every important hazard has been identified. The quality of the […]
Quantitative Risk Assessment (QRA) for LNG, Hydrogen & Green Energy Facilities
Safeguard High-Hazard Energy Projects with Specialist QRA Studies As LNG, hydrogen, and green energy infrastructure continues to expand, facilities face unique process safety challenges that conventional hydrocarbon risk models cannot fully address. Cryogenic temperatures, high-pressure systems, hydrogen flammability, and emerging energy technologies require specialized risk assessment methodologies. Aura Safety provides Quantitative Risk Assessment (QRA) services […]
Role of Quantitative Risk Assessment (QRA) in Greenfield, Brownfield, and Plant Expansion Projects
Introduction Every industrial project introduces new risks. Whether constructing a new processing facility, modernizing an existing plant, or expanding production capacity, understanding those risks before work begins is essential for protecting people, assets, operations, and the environment. A Quantitative Risk Assessment (QRA) provides a structured, data-driven evaluation of major accident hazards. Unlike qualitative assessments that […]
