Quantitative Risk Assessments (QRA) 

We deliver QRA studies at a higher quality and at a fraction of the cost of other providers due to that we are developers and users of the most advanced drawing analysis software. The latest version of this software, which  comes after an extensive 3 year development effort with LR , is called DigiTWIN and now has far more capabilities but is still the most powerful tool for automated parts counts. 

Our Consultants have extensive experience with safety studies for both  onshore and offshore oil and gas production facilities.  Our QRA's are simply carried out faster, are more accurate and cost less because we employ the latest automated parts count methodology.  Our studies typically output: 

• Individual Fatality Risk (IRPA and PLL); • Impairment Risk, • Escalation Risk and other parameters. We optimise separation distances for muster areas and new buildings and evaluate the location in view of local or international siting guidelines. We also carry out assessments on whether risks to site personnel are tolerable. 

Our parts count software for QRA is the only one in the world that reads in a PDF of a P&ID and carries out a parts count delivering the results in a table within minutes.

 

The application will process the drawings, determine and output a list of diagram components containing: Component name , Component list ID Number,  Stream ID, Phase (Gas/Liquid), Pipe Size

 

The output is a marked up drawing and a table of results available either .txt, .xls or in .PDF format . Accuracy will be > 99%. A manual parts count in our experience is usually at 90% accuracy unless double-checked.

Building  Risk Assessments (BRA) 

Our Consultants have extensive experience with safety studies for both  onshore and offshore oil and gas production facilities.  Our QRA's are simply carried out faster, are more accurate and cost less because we employ the latest automated parts count methodology.  Our studies typically output: 

BRA studies are carried out according to API 752 or local equivalent.  Building risk assessment methodology consists of three stages. The complexity, information and required resources of the analysis increase from stage I to III.  The objective is to screen  buildings at the lowest stage possible so increasingly fewer numbers of buildings are carried over to the subsequent stage. 

 

Due to our unparalleled expertise in advanced consequence analysis we are able to 

Hazards from consequences to the building from fires, explosions, and toxic/flammable
releases, using state of the art CFD and analysis. 

The detailed work can involve:

Select and evaluate dispersion scenarios  Define representative sources and locations to capture significant consequence contributors for the facility. Carry out dispersion consequence analysis using Computational Fluid Dynamics (CFD)  for at least a number of  gas and pool release scenarios based on maximum credible events (MCEs) for the following:

 

Results for each of the buildings of interest will be tabulated and displayed on  plot plans.
