Manage risk throughout the asset lifecycle

Your management of hazards doesn’t stop with consequence analysis. Accounting for the likelihood of loss of containment scenarios and performing risk analysis is a core function of any process safety professional.​

Safeti, our Quantitative Risk Analysis (QRA) software, models both consequences and risks in one interface, giving you the means for effective management of your hazards.​

Evaluate key risk metrics for ALARP demonstration​

Individual and societal risk metrics are provided as standard: LSIR contours, FN curves and PLL. 

Risk ranking points allow you to determine the risk at any location on your map and identify major risk contributors.​

With flexible ways to setup your study and perform sensitivity studies, it's easy to evaluate the impact of risk reduction measures identified as part of your ALARP demonstration process.​

Risk-based design for cost-effective operations​

Why prevent the worst case consequence when it has a one in a million chance of occurring? ​

Many regulations around the world allow for risk-based design, where risks are mitigated in areas where it matters most.​

Safeti software supports easy identification of the highest risk contributors, so that meaningful mitigation measures can be proposed by your stakeholders and evaluated further for their risk impact.​

Move your QRA beyond a box-ticking exercise and take real action from your risk data.​

Safeti software extensions for in-depth analysis

Safeti offers extensions that enhance the modelling capabilities and provide a deeper insight into the quantitative risk analysis of complex scenarios.

Explosions extension for performing occupied buildings risk assessment. The extension provides:

  • explosion calculations in three dimensions
  • building vulnerability modelling​
  • overpressure and thermal radiation exceedance curves​
  • frequency contours for consequence effects​

Multi-Component (MC) extension for advanced modelling of complex mixtures (e.g. two-phase releases).
