Digital PHA
Safer processes with less effort
A Digital Process Hazard Analysis (DPHA) takes advantage of new digital technologies to transform traditional PHAs and manage human resources wisely. The results are faster and more consistent and precise, leveraging human brain power where it’s most beneficial.
The family of methodologies classified as Process Hazard Analyses (HAZOP, LOPA, etc.) have undergone few changes over the last sixty years—until now. Our new Digital PHA leverages process modeling to simulate scenarios and a DEKRA-designed artificial intelligence solution to carry out the analysis in tandem with our experts and clients.
Part of the DEKRA Safety Platform, our Digital PHA optimises the use of human resources during risk analysis, using computing power whenever possible. For example, brainstorming sessions, the most resource-intensive phase of the PHA process, can be shortened considerably with computer assistance. With this solution, we obtain a more accurate and robust insight of each process together with its hazards, risks and safeguards.
Your Benefits
- Greater precision and consistency, with quantitative results and improved foresight
- Optimised use of resources for efficiency and cost reduction
- Time savings of approximately 70%
Our approach
The DEKRA Digital PHA (Process Hazard Analysis) incorporates computer process modeling and our own artificial intelligence solution in the DEKRA Safety Platform to enhance and refine the traditional process. We deploy digital support to reduce the time investment where possible. The steps are:
- Preparation: DEKRA experts work with the client to gather necessary information and define relevant scenarios.
- Simulation: Thanks to process modeling and computational support, the Digital PHA entrusts the calculation of causes, consequences and safeguard identification to a computer simulation, which operates much more quickly and precisely than human brainstorming.
- Review of results: Once the computer generates its suggestions, humans can review the results, make recommendations and consider additional safeguards or focus on problem solving.
These three steps are repeated for all of the scenarios identified for analysis. The Digital PHA concludes with a written report detailing the results.
When can a digital Process Hazard Analysis replace a conventional PHA?
In short, always. However, since the digital PHA is one of many tools in the PHA toolkit, we might use the following questions as a guide for deciding when a digital hazard analysis is most useful:
- How difficult is it to build a model for the plant and its processes?
- How much and what kind of information do you expect from your PHA? In other words, how much bang do you require for your buck?
The chart shows an applicability map for digital PHAs, conventional PHAs and other solutions.
A DEKRA Process Safety expert can advise you on the optimal tool to use for specific plants and processes.

How are results delivered?
Is a model of the process always required?
How is the model built?
How can you be sure that the model accurately represents the real plant and process?
