Phast™ is a globally adopted solution for modelling discharge, dispersion, fires, explosions and toxic effects of a wide range of loss of containment scenarios
Process safety professionals benefit from 40 years’ worth of development and validation by our industry experts and its continued use by more than 10,000 users across 1,000 organizations.
Phast is being used in diverse industries, including oil and gas, petrochemical, liquefied natural gas (LNG), pharmaceutical, hydrogen and ammonia, carbon capture and storage (CCS), insurance, academia, and public sector (governmental and regulatory bodies).
Displaying key results on GIS imagery
Key results overlaid on images for easy communication
Optimize your design, validate your process and meet your safety obligations
Whether it's to design a flare stack, provide input to your HAZOPs or plan for emergencies, the Phast software gives you the tools to meet your goals and to have confidence in your work.
Communicate with your customers or stakeholders using Phast's presentation of key results in 2D graphs, a 3D viewer and in Word and Excel reports.
Extensive list of scenarios available to model
Solve a range of problems with a diverse set of scenarios and effects
Loss of containment scenarios from pressure vessels, storage tanks, pipework and pipelines are easy to create. Phast automatically determines the type and extent of the consequence effects.
Within a matter of seconds, you can have the answer to the problem you are trying to solve.
Also supported are a range of "standalone" models, user-defined sources and adjustable parameters, giving you full control for specifying loss of containment scenarios.
Modelling scenarios in 3D using the CFD add-on
Phast software add-ons for in-depth analysis
Phast offers add-ons that enhance modelling capabilities and provide deeper insight into the consequences of complex scenarios.
Extended Explosions add-on brings analysis of explosions in three dimensions, directional modelling effects and visualisation of combined effect contours.
Solid Explosions add-on for modelling the consequences of solid explosions, utilizing recognized standards for overpressure predictions.
Phast pricing and licencing
Choose between an Individual licence - from 5,921 EUR per month - recommended when there is no need to share licences, or a Network licence - from 6,966 EUR per month- recommended when there is need for multiple users at the same time.
Phast/Safeti calculates the discharge, dispersion and flammable and toxic effects associated with loss of containment scenarios. It can be used to model pool spreading and evaporation, fires (jet, pool and fireballs), explosions, BLEVE and toxic effects.
Phast is typically used in the following applications:
ALARP demonstration
Consequence estimation for HAZOP, HAZID, PHA, LOPA
Consequence input to your own QRA tool
Emergency response planning
Equipment design
Escalation assessment
Extent and severity assessment
Facility siting and layout optimisation
Hazardous area classification
Regulatory obligations (e.g. safety reports)
Vent and flare design
Other general consequence estimation
We offer lease and subscription options ranging from 1 month to 3 years, as well as perpetual licenses. These can be purchased digitally via credit card or invoice through our Veracity marketplace.
Alternatively, both subscription and perpetual options are available by contacting us.
