Save lives by understanding fire, explosion and toxic effects

Our consequence analysis solutions Phast, KFX and EXSIM enable process safety professionals to understand the extent and severity of potential loss of containment scenarios involving flammable and toxic materials.

Solving a range of problems, such as designing a new vent, retrofitting blast protection to a building or specifying passive fire protection, Phast, KFX and EXSIM are applicable for a range of hazardous industries, including oil & gas, chemical, petrochemical, energy transition, and more.

The consequence analysis software is also applicable for a range of assets, including but not limited to refineries, pipelines, LNG terminals, offshore installations, transportation and storage.

Our consequence and risk solutions - Phast, Safeti, KFX and EXSIM - give you confidence

Ensure the safety not only of your facility but of the people who depend on it.
