Safeti™ (QRA)
Comprehensive Quantitative Risk Analysis
In a resource-constrained world, business objectives are always focused on efficiency and economics. Safeti™ helps you manage risk to reduce it to As Low As Reasonably Practicable (ALARP), ensuring the ability to invest in the most optimal areas. Safeti models both consequences and risk on a single interface, integrating Computational Fluid Dynamics (CFD) simulation results to provide a more accurate assessment of major incident scenarios.
Core Values of Safeti QRA
Four essential benefits that Safeti brings to your industrial risk management process
Lifecycle Asset Risk Management
Safeti models both consequences and risk on a single interface, enabling users to effectively manage different types of risks throughout the entire operational lifecycle of industrial assets — from design, construction, to operation and maintenance.
Key Risk Index Assessment for ALARP
Safeti provides a full set of individual risk and societal risk indicators in accordance with standards: Individual Risk contours (LSIR), FN curves, and annual Probability of Loss of Life (PLL). With multiple study configurations and sensitivity analysis capabilities, users can easily evaluate the impact of risk mitigation measures following the ALARP process.
Design Based on Risk Analysis Results
Why prevent the most severe consequences when that scenario has an extremely low probability of occurrence? Many regulations worldwide allow risk-based design, where mitigation measures are prioritized in areas with genuinely high risk. Safeti helps identify the factors contributing to the highest risk to provide effective preventive measures — optimizing investment costs.
CFD Integration for Enhanced Accuracy
Safeti supports the integration of detailed Computational Fluid Dynamics (CFD) simulation results into risk analysis. Users can import .asc files from Phast CFD tools or third-party software, enabling more accurate representation of complex scenarios — particularly in the assessment of major incidents. This feature is available from Safeti version 9.1 onwards.

Frequently Asked Questions about Safeti QRA
Quick answers to common questions from process safety engineers and managers
In addition to the consequence analysis features of Phast, Safeti is commonly used for: cost-benefit analysis, fire and explosion risk assessment (FERA), occupied building risk assessment (OBRA), quantitative risk analysis (QRA), risk-based design, and sensitivity analysis.
Safeti offers a range of flexible subscription and licensing options: subscriptions from 1 day to 3 years, as well as perpetual licenses. Subscription options can be purchased online through DNV’s Veracity platform by credit card or through a sales representative.
Phast focuses on incident consequence analysis (modeling fires, explosions, gas dispersion). Safeti encompasses the full capabilities of Phast and adds quantitative risk analysis capabilities — calculating scenario frequencies, individual risk contours (LSIR), FN curves, and annual probability of loss of life (PLL).
Yes. From version 9.1 onwards, Safeti allows the import of .asc files containing Computational Fluid Dynamics (CFD) simulation results from Phast CFD tools or third-party software. This feature enhances the accuracy of risk assessments, particularly for complex major incident scenarios.
