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.
Technical Features of Safeti QRA
A comprehensive toolkit for consequence analysis, risk assessment, and risk-based design.
Consequence & Risk Modeling on a Single Interface
Safeti integrates the full consequence analysis capabilities of Phast (toxic gas dispersion, fires, explosions) with quantitative risk assessment on a single, unified interface. Users do not need to switch between different software — from modeling containment loss incidents to calculating individual and societal risk, everything is performed in one seamless workflow.
Standard Risk Indicators – LSIR, FN, PLL
Safeti provides a full set of standard risk indicators including: Location-Specific Individual Risk contours (LSIR), FN curves (frequency – number of people affected), and annual Probability of Loss of Life (PLL). Risk Ranking Points allow risk to be determined at any location on the grid and enable identification of the key risk-contributing factors.
Occupied Building Risk Assessment (OBRA)
The Extended Explosions module provides Occupied Building Risk Assessment (OBRA) capability with four key functions: explosion calculation on a 3D platform, risk hotspot modeling for buildings, construction of overpressure and thermal radiation frequency curves, and generation of consequence risk impact frequency contours.
Multi-Component Module
The Multi-Component (MC) add-on enables advanced modeling of mixed compositions, including two-phase releases. This is an essential feature when assessing risk from systems containing multi-component chemical mixtures in the petrochemical and gas processing industries.
Solid Explosions Module
The Solid Explosions add-on enables consequence and risk modeling from solid substance explosions, using recognized standards to estimate overpressure. This feature extends the scope of risk assessment to types of incidents beyond the traditional range of fires and gas explosions.
Sensitivity Analysis & Cost–Benefit Analysis
Safeti supports flexible sensitivity analysis setup, allowing users to evaluate the impact of each individual risk mitigation measure. Combined with cost-benefit analysis, Safeti helps convert risk data into concrete actions — not merely a regulatory compliance exercise, but a genuine decision-making tool.
Safeti QRA Application Industry
Quantitative risk analysis solution for industries with high incident potential
Oil & Gas
Safeti supports comprehensive risk assessment for oil and gas exploration, processing, and transportation facilities — including oil refineries, offshore drilling platforms, and LNG plants. The software models toxic gas dispersion, fire, and explosion scenarios characteristic of the oil and gas industry, providing risk indicators for international regulatory compliance.
Chemicals & Petrochemicals
The chemical and petrochemical industries handle a wide variety of multi-component chemical mixtures, posing complex modeling challenges. Safeti, with the Multi-Component add-on, allows two-phase release simulation analysis from systems containing complex mixtures — from chemical manufacturing plants to storage and distribution facilities.
New Energy
In the context of the global energy transition, Safeti supports the modeling of hydrogen and carbon dioxide (CO₂) emissions for clean energy and carbon capture projects. Its quantitative risk assessment capability for new scenarios — specific to hydrogen and CO₂ — helps ensure safety for new energy infrastructure.
Industrial & Civil Infrastructure
Safeti supports risk assessment for occupied buildings located near facilities with major accident hazards — including offices, residential buildings, and public structures. The Extended Explosions module provides 3D explosion analysis, building vulnerability modeling, and consequence frequency curves, serving OBRA assessments in accordance with regulatory requirements.
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.
