Refine & Validate Current & Proposed Engineering Designs

Variety of Approaches to Aid in Client Compliance

Consequence Modeling and Quantitative Risk Assessment (QRA)

We work closely with our clients to create a comprehensive quantitative risk assessment (QRA) for hazards, predict 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 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 can leverage our modeling capabilities to prove or disprove accident causation scenarios developed after a catastrophic loss incident.

REPRESENTATIVE CAPABILITIES:

risk assessmentWe 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 works 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 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 can calculate 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 unpressurized vessels or pipes can be modeled.  An integral-type dispersion model called UDM (Unified Dispersion Model) calculates several consequence results including:

  • 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 (this is the exact same copy as above)

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 unpressurized vessels or pipes can be modeled. An integral-type dispersion model called UDM (Unified Dispersion Model) calculates several consequence results including:

  • 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
