The PLANTSERV® team also offers Safety Integrity Level (SIL) Assessments, Layer of Protection Analyses (LOPA) and Consequence Modelling with Quantitative Risk Assessment (QRA) Studies. These structured approaches provide a thorough evaluation of risks and safeguards to support compliance and effective risk management. Here also, our experts rely on detailed inputs and supporting documents, such as PFDs, P&IDs, equipment data and site-specific risk factors. They use advanced tools for accurate and actionable outcomes.
SIL Assessments and LOPA focus on evaluating safety instrumented functions (SIF) and defining protection layers to mitigate risks for specific scenarios. SIL Assessments focus on evaluating safety instrumented functions (SIF) and defining protection layers to mitigate risks for specific scenarios. SIL Assessments determine the required SIL levels for compliance with IEC 61511 standards, while LOPA assess initiating event frequencies, independent protection layers and risk tolerance criteria drawn from HAZOP reviews.
Consequence Modelling and QRA Studies analyze potential hazards to assess risks and impacts on people, facilities and critical elements. Consequence Modelling covers hazard scenarios such as cloud dispersion, explosion impacts and fire behavior (e.g., jet fires, BLEVE, fireballs). QRA, on the other hand, quantifies risks to individuals and groups, evaluates iso-risk contours and benchmarks tolerance levels against company, industry or regulatory standards. These analyses utilize tools like DNV PHAST™, Fire Dynamic Simulator (FDS), PyroSim, and DNV Safeti™ for precise modeling and decision support.
