BREEZE Software has a 20-plus year history of explosion modeling, including both developing modeling software and executing modeling analyses for clients. BREEZE supports two explosion modeling software suites, Incident Analyst and ExDAM, which together contain seven explosion models. In addition to this experience, the group has partnerships with several explosion modeling experts in the private sector, government, and academia in order to stay on top of the latest developments in the field.

BREEZE's explosion modeling expertise covers a wide range of situations, industries, and applications that include both vapor cloud and high-explosive material explosions. Common explosion modeling projects include:

  • U.S. EPA Risk Management Program (RMP) Off-site Consequence Analysis (OCA) assessments
  • Siting analyses for sensitive structures such as plant control rooms and portable buildings
  • Explosion consequence analyses (ECA) for risk assessment purposes
  • Reconstruction of events for investigative or litigation purposes
  • Regulatory compliance
  • Facility siting studies
  • Locating permanent and portable buildings (API 752/753)
  • Overpressure Exceedance Analysis (OEA)
  • Quantitative Risk Assessment (QRA)
  • Consequence mitigation design and testing
  • Emergency Response Plan (ERP) development
  • Real-time emergency response system
  • Event reconstruction and forensics analysis
  • Security and vulnerability assessments
  • Event planning and security
  • Force protection modeling, simulation, and analysis
  • Perimeter analysis (standoff distance determination)
  • New site/facility design

Some of the analyses listed above are performed for clients in the refining, chemical/petrochemical, and oil and gas production sectors to ensure regulatory compliance or analyze potential onsite and offsite impacts. Other analyses are performed for defense agencies, insurance companies, and consulting firms to model terrorism-related threats and evaluate blast overpressure and damage to structures and injury to people.

Project Snapshot-Explosion ModelingProject Snapshot: Explosion Modeling

BREEZE conducted a hazard assessment for conservative overpressure scenarios at a petrochemical complex, which included an offsite consequence analysis to provide guidance concerning the effects of explosive blasts on persons, structures, and buildings. BREEZE was asked to determine the potential impact of worst-case and most likely accidental release scenarios. In this project the worst-case explosion scenario involved a release due to tank/drum leakage and explosion involved release due to a pipe rupture. BREEZE Incident Analyst was used to compute the evaporation rate of selected substances and BREEZE ExDAM was used to build facility structures. ExDAM applies the theory of distance/damage correlations, pressure/impulse/damage correlations, blast effect curves, blast resistance of buildings, and human injury resistance to blasts in each designed scenario. Vapor cloud explosion blast consequence was analyzed using BREEZE ExDAM in terms of overpressure, structure damage, and human injury.
