Refine & Validate Current & Proposed Engineering Designs

Variety of Approaches to Aid in Client Compliance

Consequence Modeling and Quantitative Risk Assessment (QRA)

IFO Group works closely with clients to identify and understand their potential fire, explosion and toxic release hazards, predict the consequences of various scenarios, and fully assess weaknesses that may cause catastrophic failures.  We are also very familiar with the requirements for performing offsite consequence modeling and analysis to assist with EPA RMP and OSHA PSM compliance efforts and facility siting studies. 

Our experts have performed numerous consequence modeling analyses and studies in order to refine and validate current and proposed engineering designs.  We have performed work on projects ranging from design validation of structures and systems in refineries and chemical plants to offshore production platforms. Additionally, our clients are able to leverage our modeling capabilities to prove or disprove accident causation scenarios developed after a catastrophic loss incident.

REPRESENTATIVE CAPABILITIES:

We use a variety of approaches to aid in client compliance and upon request, can utilize the following software packages to aid risk management decision making:

  • DNV GL – Phast
  • Safeti
  • RMP*Comp
  • ALOHA
  • DEGADIS
  • SLAB
  • FLACS CFD
  • FDS (Fire Dynamics Simulator)
  • CFAST (Consolidated Model of Fire and Smoke Transport)

 

Fire and Explosion Modeling

Our staff work closely with clients to identify and understand their potential fire and explosion hazards, predict the consequences of explosions, fire growth and spread, and fully assess weaknesses that may be vulnerable to fires and explosions and their effects.

We have performed numerous fire and explosion modeling analyses and studies in order to refine and validate current and proposed engineering designs. We have performed work on projects ranging from large commercial logistical occupancies to the design validation of fire protection equipment and systems in refineries and offshore production platforms.  The models are capable of calculating a number of consequence results:

  • jet fire intensities
  • flash fire envelopes
  • explosion overpressures
  • thermal radiation profiles

 

Toxic Hazard Modeling

Toxic Hazard Modeling examines a potential incident scenario from the initial release to far field dispersion, including modeling of pool vaporization and evaporation, and flammable and toxic effects. Various release scenarios such as leaks, line ruptures, long pipeline releases and tank roof collapse in pressurized and unpressurised vessels or pipes can be modeled.  An integral-type dispersion model called UDM (Unified Dispersion Model) calculates several consequence results:

  • cloud behavior
  • transition through various stages such as jet phase, heavy phase, transition phase and passive dispersion phase
  • distance to hazardous concentration of interest
  • footprint of the cloud at a given time

 

Discharge and Dispersion Modeling

Discharge and Dispersion Modeling examines a potential incident scenario from the initial release to far field dispersion, including rate of release and phase, modeling of pool vaporization and evaporation, and flammable and toxic effects. Various release scenarios such as leaks, line ruptures, long pipeline releases and tank roof collapse in pressurized and unpressurised vessels or pipes can be modeled. An integral-type dispersion model called UDM (Unified Dispersion Model) calculates several consequence results:

  • cloud behavior
  • transition through various stages such as jet phase, heavy phase, transition phase and passive dispersion phase
  • distance to hazardous concentration of interest
  • footprint of the cloud at a given time
