Quantitative Risk Assessment (QRA) is a formal method of quantifying consequences and likelihood of hazardous events, and estimating the risk for benchmarking and risk management.

Bell Energy has multidisciplinary teams located globally who offer the entire range of QRA services for onshore, offshore and floating Oil & Gas facilities, refineries, petrochemicals, chemical, nuclear and transport facilities. Bell Energy is a leading consultant in the field of fire and explosion modeling using Computational Fluid Dynamics (CFD).

Highlights

  • Analyze potential accident scenarios such as leaks and ruptures and determine their consequences in terms of gas dispersion, fire and explosion impact.
  • Estimate risk to employees and public
  • Estimate risk of economic loss in terms of assets and production
  • Predict impacts to environment
  • Estimate fatalities (individual risk, societal and group risk)
  • Bell Energy has consultants globally who provide expert risk advisory solutions that can benefit operators in reducing their risk exposure and insurance premiums.
  • Benefit from ASPIRE software, a cloud-based QRA workbench that includes insights and data-analytics, assisting companies in benchmarking with Industry majors.

Why companies perform QRA

Companies take risks to gain benefits and increase revenue. The owner or CEO of a company is the primary risk manager. Bell Energy’s role is to advise the risk manager on when these risks are intolerable and what needs to be done to reduce the risks to as low as reasonably practicable (ALARP). It is vital to measure and understand risks so that informed decisions can be taken, well in advance. QRA is one such technique used to quantify risks and measure the benefits of risk reduction measures.

QRA is performed in a multidisciplinary team comprised of operations, maintenance, process engineering, process safety, instrumentation, electrical, risk management and project management personnel.

QRAs performed for a chemical process or nuclear industry helps in determining safe facility layout, determining the maximum inventory of hazardous material that should be stored or processed at any time, use of technology that minimizes the potential for undesired release to atmosphere, minimize potential for run-away reactions. QRA in general can be used to determine mitigation and recovery measures such as fire protection system, emergency response plans. Urban planning commissions can use QRA to site public facilities such as schools, hospitals, infrastructure around industrial area.

QRA takes input from hazard identification studies such as HAZID and HAZOP.

Bell Energy’s value added service

Bell Energy performs a wide range of services that leverages on the ability of QRA to manage risks effectively. Some of these services are considered standalone or combined along with a QRA study:
  • Hazard Identification through HAZID and HAZOP
  • Development of Technical Safety and Risk Management Procedures and processes
  • Analysis of consequences of toxic and flammable gas dispersion, jet fire, pool fire, flash fire, Boiling Liquid Expanding Vapour Explosion (BLEVE), vapour cloud explosion and confined explosions
  • Estimate the likelihood of release and ignition
  • Estimate the potential for exposure to employees, public
  • Estimate the effect of hazardous events onto occupied buildings, control rooms, local equipment rooms, temporary refuges in a Building Risk Assessment
  • Determine the blast design requirements on buildings and structures using Computational Fluid Dynamics
  • Determine the requirement for fire proofing, active fire protection in a Fire Risk Assessment (FRA) study
  • Determine specific toxic risk zones for minimizing employee and public toxic exposure in a Toxic Risk Zoning Study
  • Analyze the effectiveness of escape, egress, evacuation and rescue arrangements in a systematic EEERA study
  • Determine the survivability of Emergency Systems or Safety Critical Elements in a ESSA study
  • Determine the risk during transport on land (rail or road), helicopter or marine in a Transport Risk Assessment
  • Determine the risk of structural failure in case of a marine vessel impact in a Marine Risk Assessment
  • Determine the risk of dropped objects impacting on subsea pipelines and cables in a Dropped Object Study.
  • Determine the risk of Simultaneous Operations (SIMOPs) offshore and onshore
  • Facilitate a multi-disciplinary Risk Reduction workshop
  • Provide training on Quantitative Risk Assessment
  • Perform audit and design verification to ensure adequate close-out of QRA actions
