Phast and Safeti 9.1 are software tools developed by DNV for process safety and risk management, widely used in industries like oil and gas, petrochemicals, hydrogen, ammonia, and carbon capture and storage (CCS). Below is a concise overview based on available information:

Phast 9.1

  • Purpose: A consequence analysis tool for modeling the impacts of hazardous material releases, including discharge, dispersion, fires, explosions, and toxic effects.
  • Key Features:
    • Models a wide range of loss-of-containment scenarios to assess hazards and potential casualties.
    • Supports safety studies like HAZOP, HAZID, PHA, and LOPA with comprehensive visualization in 2D graphs, 3D viewer, and reports (Word/Excel).
    • New in 9.1:
      • CFD Dispersion Modelling: Powered by KFX™, it enhances accuracy for vapor, two-phase, and liquid flammable releases, considering 3D geometry (requires Phast CFD license)
      • Points of Interest: Allows defining critical locations for detailed consequence analysis
        Applications: Designing flare stacks, emergency response planning, and regulatory compliance.
    • Industries: Oil and gas, LNG, pharmaceuticals, hydrogen, CCS, insurance, academia, and government.
    • Validation: Backed by 40 years of development and extensive validation, including the UDM Outcome Model for efficient event prediction.

Safeti 9.1

  • Purpose: Industry-standard software for Quantitative Risk Analysis (QRA), evaluating and managing risks associated with hazardous operations.
  • Key Features:
    • Performs comprehensive QRA to assess risk profiles for operations involving hazardous materials.
    • Supports Occupied Buildings Risk Assessments (OBRA) and compliance with regulations.
    • New in Safeti 9.1:
      • New Ignition Models: Based on Norwegian Directorate for Civil Protection guidelines, improving ignition probability predictions.
      • Dynamic Pressure Exceedance Curves: Enhances analysis of overpressure effects for blast-resistant structure design.Add-ons:
      • Explosions add-on for occupied buildings risk assessment.
      • Multi-Component (MC) add-on for modeling complex mixtures
      • Solid explosions modeling based on Kingery & Bulmash and GB/T 37243 standards.
    • Applications: Gas transmission pipelines, hazardous material management, and risk mitigation strategy development.
