Software for Risk Assessment

Consequence Modeling Software, CFD, Industry picture

Quest uses a number of software packages to perform its process safety and risk assessment services. Quest engineers developed many of these tools, utilizing them and other industry standard software packages for various components of the modeling process.


Consequence Analysis: CANARY by Quest

CANARY by Quest provides Consequence Analysis for releases of hazardous fluids. This software package is a necessary tool in performing QRAs and siting studies. Studies prepared with CANARY have been presented to and approved by governments and regulatory agencies around the world.

CANARY Features

  • Multicomponent Thermodynamics
  • Phase Validation
  • Liquid, Vapor, and Two-phase Transient Releases
  • Transient Pool Vaporization
  • Vapor Dispersion
  • Pool Fires
  • Jet Fires
  • Explosions
  • BLEVEs

Risk Analysis: CANARY+

Quest developed CANARY+ as an in-house tool to work in conjunction with CANARY in performing quantitative risk analyses.  These studies produce several measures of risk, depending on the particular study. Read more→
