Quantitative Risk Analysis (QRA) – including a full range of fire, explosion, and dispersion modeling using gaussian, analytical equations, and computational fluid dynamics (CFD) techniques, facilitating decision making for facility siting, permitting, and special analysis of high-risk scenarios.
We perform a variety of risk analysis for complicated scenarios. In fire and gas modeling, we develop the consequence models for fires, explosions, gas dispersion, and computational fluid dynamics (CFD). Gas dispersion outdoors is normally modeled using gaussian, while gas modeling inside a facility or restricted area is done using CFD.
Gaussian Modeling is useful in determining how a gas will disperse as it leaves a leak outside, in an unobstructed space. once the leak hits another object, then the dispersion characteristics change and consideration will be made based on the scenario to use CFD. By modeling a typical leak and then using the model many times at key points in a process, like 360 degrees around a flange, provides a much better analysis for determining what will happen and then the probability of detecting it with a gas detector.
Computational Fluid Dynamics has proven extremely useful in determining the migration of gas in confined spaces like labs, buildings, compressor stations, test stands, battery testing facilities, battery storage facilities, offshore platforms between the decks where space can be confined and finally in drilling rigs where space is getting more confined as rigs get more capable.
Facility Siting assesses hazards and the potential damage that an explosion, fire, or toxic chemical incident could cause. Obviously there is a focus on occupied building both inside and outside of the fence.
Failure Mode and Effects Analysis (FMEA) falls into a broader category of reliability engineering that we perform. FMEA analyzes all the components of a system to identify failures, probability, and their causes and effects.
