SIL Assessment (with LOPA Methodology) Training for Engineers

About Course
The need for functional safety expertise is ever increasing and a growing challenge in the hydrocarbon, petrochemicals and chemicals industry across the globe. The energy demands over the past decade, especially in the Emerging Economies, have seen an exponential growth in the hydrocarbon and allied sectors. This has resulted in incidents related Process Safety such as explosions and release of toxic gases resulting in fatalities and injuries.
USPEnergies is an organization with expertise in the domain of functional Safety. USPEnergies is now offering training program focusing on SIL assessment with LOPA Methodology.
LOPA is an acronym for Layers Of Protection Analysis. The method starts with data developed in the Hazard and Operability study (HAZOP) and considers each identified hazard by documenting the initiating cause or causes and the corresponding protection layers that prevent or mitigate the hazard. The total risk reduction can then be determined; the need for further risk reduction can be analyzed based on the corporate risk tolerance criteria. If additional risk reduction is required and if it is to be provided in the form of a Safety Instrumented Function (SIF), LOPA methodology allows the determination of the appropriate Safety Integrity Level (SIL) for the SIF. The safety lifecycle defined in IEC 61511-1 requires the determination of a safety integrity level for the design of a safety-instrumented function.
LOPA training is provided by an expert trainer, Umesh Goel with over thirty years of experience industry, utilizing a practical and interactive approach. The session includes several work-shops and mock LOPA studies, thus giving the candidates invaluable hands-on-experience.
