Bow Tie Analysis: Visualising How Major Accidents Happen and How to Stop Them
Major accidents rarely come from a single failure. When several small failures line up, like the holes in slices of Swiss cheese, a serious incident occurs. Bow Tie Analysis replaces pages of complex text with an auditable visual map that operators and executives can both understand. What is Bow Tie Analysis? Bow Tie Analysis is […]
LOPA and SIL Determination: Replacing Guesswork with Quantitative Rigour
When engineering teams rely only on qualitative risk graphs or gut feeling, two costly mistakes occur: expensive SIL 3 loops are over-specified, or high-consequence Major Accident Hazards (MAHs) are under-protected. Layer of Protection Analysis (LOPA) is the semi-quantitative method that removes the guesswork. It sits between qualitative HAZOP and detailed SIL assessment and supports compliance […]
ALARP: How Far Should You Go to Reduce Process Risk?
In major hazard industries, safety is not about eliminating all risk, because no industrial operation is entirely risk-free. The real objective is to show that risk has been reduced to a level that is As Low As Reasonably Practicable (ALARP). The central challenge is judging whether a safeguard is truly proportionate to the risk, or […]
Fire and Explosion Risk Assessment (FERA)
In oil and gas, petrochemical and chemical facilities, fire and explosion hazards are among the most critical safety concerns. A Fire and Explosion Risk Assessment (FERA) gives operators a structured, quantitative framework to identify, evaluate and control these hazards, protecting people, assets and the environment. It is used on both onshore and offshore processing facilities. […]
Quantitative Risk Assessment(QRA): A Complete Guide for High-Hazard Facilities
In oil and gas, petrochemical, chemical, power and pipeline facilities, major accidents can cause severe harm to people, assets and the environment. Qualitative tools such as HAZOP and HAZID are excellent at finding hazards, but they cannot tell you how likely a major accident is or how many people it could affect. That is the […]
