We support companies in identifying the risks in complex systems or entire production processes using the most widespread HazOp, PHA, QRA, or LOPA techniques in reference to the main standards for risk assessment and functional safety.
Qualitative-quantitative analysis of process risks
Risks associated to complex systems or entire production processes are identified, estimated, and analyzed based on deviations, whether accidental or not, of essential parameters of the main physical quantities that characterize the process being assessed.
These risk assessment techniques are based on teamwork in which we support companies through a service that covers all the main applicable analysis techniques according to international standards.
Based on what is needed, we develop the following types of analysis:
- HazOp (Hazard and Operability), group analysis that is carried out on the IEC 61882 standard guidelines with the goal of identifying diversions from the intention of the design that can provoke safety issues
- PHA (Preliminary Hazard Analysis), analysis to identify, classify, and describe failures, their origins and possible consequences, and measures for mitigation
- QRA (Quantitative Risk Assessment), analysis based on the probability and consequences of events that are dangerous to people, the environment, and the asset
- LOPA (Layer of Protection Analysis), quantitative risk analysis according to the IEC 61511-2 standard for one or more accidental scenarios classified based on the severity of the consequences and how frequently they occur.
Our specialized consultants will help you identify risks, proposing tailored solutions based on the most appropriate technique for the type of process being assessed.
HazOp, or Hazard and Operability Analysis, is a risk analysis technique defined by the international IEC 61882 standard to assess workplaces and identify the dangers to which workers are exposed. In particular, the HazOp technique is conducted through a group analysis to identify how the production process can be diverted, which could generate accidents and compromise safety.
PHA, or Preliminary Hazard Analysis, is a system risk analysis technique based on analyzing the safety and reliability of the systems themselves and how they can be improved using appropriate measures for mitigation.
LOPA, or Layer of Protection Analysis, is an advanced technique for process safety analysis based on quantitative risk analysis according to the IEC 61511-2 standard, which classifies several causes of risk that are independent of each other based on the severity and frequency of the possible occurrences.
