DNV GL AS Phast & Safeti Onshore 8.4.165.0

The DNV GL development team is pleased to announce the availability of DNV GL AS Phast & Safeti Offshore 8.4. QRA software package that has become the industry standard for quantitative risk analysis for industries that work with hazardous materials.

The improvements Phast/Safeti 8.4 include:
- A new, 64-bit architecture, providing significant performance benefits, particularly for large studies
- Explosion and thermal radiation exceedance curves where detailed results have been turned off
- New event tree ignition report, providing immediate and delayed ignition probabilities and frequencies
- Improvements to the GIS, making it easier to transfer data to/from other GIS such as Google Earth, ArcGIS and QGIS
- Toxic effect contours for defined ERPG concentrations
- Improvements to make it easier to specify long pipeline releases
- New materials in the standard list
- An upgrade to the 2018 version of the DIPPR database


A Quantitative Risk Assessment (QRA) is a formal and systematic risk analysis approach to quantifying the risks associated with the operation of an engineering process. The main objective QRA (Quantitative Risk Analysis) is to determine the potential risks of major disasters having damage potential to life and property and provide a scientific basis for decision makers to be satisfied about the safety levels of the facilities to be set up.

PHAST (Process Hazard Analysis Software Tools) is a Windows–based toolkit, which determines the consequences of accidental releases of hazardous material. It examines the progress of a potential incident from initial release, through forma-tion of a cloud, with or without a pool, to its dispersion. The program uses DNV's unique Unified Dispersion Model (UDM) to apply the appropriate entrainment and dispersion models as the conditions change and to integrate the relevant individual models such that the transition from one behaviour pattern to another is smooth, continuous and automatic. It is applicable to all stages of design and operation across a range of process and chemical industry sectors and may be used to identify situations which present potential hazards to life, property or the environment.

SAFETI (Software for the Assessment of Flammable, Explosive and Toxic Im-pact) is the most comprehensive and widely used onshore QRA package available. It is a Windows based system that provides a user friendly, industry standard method for quantifying major chemical risks. It enables analysis of the likelihood and severity of major hazards and makes use of the PHAST models to predict the consequence of major releases. By combining these with their frequencies and taking account of population location and density, along with ignition source location for flammable and explosive effects, a number of presentations of 'risk' are possible. These include risk contours, F/N curves, risk transects and risk ranking at specific points.
