Phast™ and Safeti 8.71 – Key updates and FAQ
The latest upgrade available for Phast and Safeti is 8.71.
Our recent releases leading up to 8.71 come with key updates including (1) the addition of CFD calculation capabilities for jet fires and pool fires, plus (2) an expanded materials library to support both classic and CFD calculations. Please note that the CFD capabilities are only available on Phast, but not on Safeti.
Who should consider an upgrade?
Users who are looking forward to CFD modelling capabilities, or simply want to have the latest features to keep up with the industry, should consider upgrading to the latest version. You should also consider upgrading if you have an older version (e.g. Phast/Phast Risk 6.7 or Phast/Safeti 7) to take advantage of the latest features and improvements that we have introduced into the software over the years. In general, it is not recommended to have outdated software that hasn’t been updated in a long time. Older versions also tend to be less efficient and may not be supported in the future.
Am I eligible for upgrades?
DNV customers with service level agreements (SLAs) are eligible for upgrades free of charge since it is included in the contract. Customers that do not have SLAs can also upgrade to the latest version, but there’s a cost associated with it. These customers can contact our sales team to get more information.
What am I missing out? What are the latest features in recent releases?
- CFD modelling capability:
In version 8.6, we added the CFD modelling capability for modelling a standalone pool fire. In version 8.7/8.71, we added CFD modelling capability for jet fires. These are very good improvements that we’re seeing by integrating some CFD modelling capabilities from KFX, which is another tool that we have in our software portfolio. In previous versions, users could only do an empirical modelling using the existing correlations available in the software, but now with the latest version, users can model a jet fire or a pool fire utilizing this CFD modelling capability. The input for modelling a CFD calculation is relatively very simple within the Phast user interface. It is a very big step forward to be able to integrate the KFX and the Phast software tools. - 2018 DIPPR Database with expanded default materials list:
The default material database has been expanded. Previously, the database only had about 60 materials in the library. Now, there’s about 100+ different components, including heavier hydrocarbons, which were also added to the list. - Modelling improvements related to energy transition (e.g., hydrogen jet fire model):
Energy transition is a really popular topic in the modelling community. There’s a lot of interest in modelling hydrogen, ammonia, and energy transition applications. For this reason, we have been constantly improving our models, doing validation for modelling ammonia, hydrogen, and carbon dioxide. We have done some revalidation work and introduced modelling improvements in recent years. One example here would be the hydrogen jet fire model, which is also known as the Miller model.
DNV published a recommendation for CO2 and implemented some modelling improvements for CO2. We also produced a hydrogen guidance document recently. The two documents can be found on our customer portal.
Where do I get the latest version and read the release notes?
The latest version and release notes, with dates for each release, are available through our customer portal – all our SLA customers have access to this site. The release notes include detailed information about each version.
Top applications for Phast
Phast is a globally adopted solution for modelling discharge, dispersion, fires, explosions and toxic effects of a wide range of loss of containment scenarios. Great for:
- Accident and incident investigation
- Consequence estimation for HAZOP, HAZID, PHA and LOPA
- Emergency response planning
- Equipment design, facility siting and layout optimization
- Regulatory obligations (e.g. safety reports)
- Other general consequence estimation
Top features for Safeti
Safeti is our quantitative risk analysis (QRA) solution, which enables professionals to firstly understand the consequence and risk of their process safety hazards and secondly to prioritize areas for risk reduction so that the business can be both safe and profitable.
Safeti incorporates our Phast consequence analysis software and calculates risk based on user-provided leak frequencies, ignition data, weather data, populations, and vulnerability data.
Safeti includes Phast and is great for:
- Cost-benefit analysis
- Fire and explosion risk assessment (FERA)
- Occupied buildings risk assessment (OBRA)
- Quantitative risk analysis (QRA)
- Risk-based design
- Sensitivity analysis
