Consequence Modelling and Quantitative Assessment

Prosaris has highly skilled personnel experienced in the use of PHAST for consequence modelling of process hazards and SAFETI for quantitative risk analysis.

We support our clients with modelling reviews and study development for large and small projects, both onshore and offshore. We have extensive experience in the review and development of quantitative and consequence based hazard assessments of complex and critical operations to support our clients’ decision making process and to provide technical support for operational changes. Our consequence and quantitative assessment studies provide our clients with a robust technical position from which to provide, manage, and maintain cost effective risk management solutions on their facility.

Consequence Modelling

  • Highly skilled and experienced in the use of PHAST for modelling of process hazard consequences.
  • Completed studies for onshore and offshore oil and gas facilities, drilling and production operations, and major SIMOPS campaigns where stringent regulatory requirements govern the positioning of temporary office locations and personnel. We excel at complex and highly focused studies of specific hazards associated with critical operations and activities where the complexity of the case requires support of highly skilled and experienced PHAST practitioners.
  • Support facility expansion projects and product spec. changes where flammable and toxic hazards present new risks to personnel and adjacent industry and public.
  • Venting and flaring studies.
  • Support to emergency response planning through development of scenario driven consequence model plans.

Quantitative Risk Assessment (QRA)

  • Highly skilled and experienced in the use of SAFETI for conducting quantitative risk assessment studies.
  • Experienced in the revalidation of design QRA’s once a facility is operating, as well as sensitivity assessments in support of operational changes to confirm that design tolerance compliance is maintained, including:
    • Changes to shutdown and depressurization arrangements.
    • Facility changes or new process equipment.
    • Changes to manning profile and facility distribution based on realized production and maintenance personnel activity.
    • Changes to personnel emergency protective equipment.
    • Changes in fire and gas detection or fire protection arrangements.

Fire and Explosion Risk Assessment (FERA)

Given our PHAST and SAFETI capabilities and process safety and risk management background, we fully satisfy our client FERA study requirements.
