Formal Safety Studies including QRA Modelling Solutions is generally a five step process.
Quantitative Risk Assessment (QRA) is a formal and systematic process of identifying and evaluating the potential hazards related with the working of an engineering process. It demonstrates the risks lying in the ALARP (as low as reasonably practicable).
Objectives of the QRA Study:
QRA is implemented on the basis of noticeable technical hazards that leads to accidents. The approach uses measurable and objective data to work out the asset values, probability of losses and the risks associated with them. Formal Safety Studies including QRA Modelling is also responsible for making cost-effective decisions to manage the risks of the complete asset lifecycle.
Elements of QRA Study:
Safety Audits, Drop Object and Work at Height Surveys for both Onshore and Offshore Rigs
Fire and Explosion Risk Assessment (FERA) is a structured and systematic process to identify and assess risks from fire and explosion hazards. The results of this assessment are used to ensure safe facility layouts, specify passive and active fire protection requirements, and to provide input for Escape and Evacuation Risk Assessment (EERA, Emergency Systems Survival Assessment (ESSA), Building Risk Assessment (BRA) and Quantitative Risk Assessment (QRA) studies.
Fire and Explosion Risk Assessment (FERA) comprises quantification of the probability of fire and explosion accidental events, and their consequences. FERA shall quantify risks to the asset associated with events caused by Loss of Containments (LOCs).
Main objectives of FERA:
Steps in Fire and Explosion Risk Assessment:
Building Risk Assessment (BRA) is a tool used to evaluate the risks to people in occupied buildings in the facility. It accurately measures the risk and identifies any improvements that are required to ensure that they are adequately safeguarded for any major accidental events.
At EERM Building Risk Assessment is carried out to assess the explosion, fire, and toxic release hazards using the three-stage process outlined by API RP 752. BRA Stage 1 and 2 involve the following steps:
