Risk analysis of complex technological systems, through, among others:
Risk identification
- Hazard and Operability Studies (HAZOP, using conventional methods, such as guide-words, and advanced techniques, such as Recursive Operability Analysis);
- FMECA – Failure Modes and Effect Analysis;
- Safety Audits;
- Preliminar Hazard Analysis (PHA);
- Hazard Identification Analysis (HazId).
Quantification of the probability of unwanted events
- Fault Tree Analysis – FTA;
- Event Tree Analysis – ETA.
- Safety integrity level – SIL
- Integrated Dynamic Decision Analysis – IDDA
Simulation of accidents consequences
Fire, explosion and toxic release modeling.
Risk representation and decision making
- Layer Of Protection Analysis – LOPA.
- Bow-Tie Analysis.
- Integrated Dynamic Decision Analysis – IDDA
- Land use planning – LUP
Analysis of the operational experience
- Analysis of accidents, near misses and anomalies occurred in the plant, to support Risk assessment;
- Analysis of the unsafe acts and unsafe conditions for preventive purposes.
