Computational Fluid Dynamics (CFD)
ESR Technology offers detailed CFD ventilation, dispersion and explosion modelling using FLACSTM
This is one of the leading CFD models and provides detailed information for use as part of the explosion, gas dispersion and ventilation management process during design. The many functions and parameters within FLACS make it applicable to both onshore and offshore facilities. FLACS has been extensively validated against experiments and can efficiently handle large geometry models as either a CAD import or as a manual build.
ESR Technology uses FLACS and post-run analysis to support its clients with the following:
- Natural Ventilation Analysis - Characterising airflow around key structures e.g. a Helideck, or demonstrating compliance with design safety criteria.
- Smoke Dispersion Analysis - Smoke dispersion modelling for specific scenarios to inform escape route impairment and muster arrangements for both fire products and for intentional combustion processes, such as exhaust gases from turbines.
- Dispersion Analysis - Gas dispersion modelling for specific scenarios of interest and probabilistic analysis to inform explosion exceedence analysis.
- Explosion Exceedence Analysis - Informing blast design decisions using probabilistic explosion exceedence.
- Explosion Loading Analysis - Providing input to structural design and design optimisation studies.
Examples of some of our FLACS™ Projects include:
- Middle Eastern Gas Processing Platform CFD Explosion and Dispersion Study – Probabilistic CFD explosion analysis of gas processing platform (EPC phase) for flammable, toxic and hot exhaust gases.
- Offshore Gas Storage Project Dispersion and Explosion Analysis – Probabilistic CFD explosion analysis of offshore gas storage platform including CFD dispersion analysis.
- Wellhead Explosion Analysis – Probabilistic explosion analysis of three Middle Eastern wellhead platforms.
- Gas Platform Probabilistic Explosion Analysis – Probabilistic explosion analysis of a North Sea platform at FEED design.
- CFD Modelling for a Large FPSO – Smoke, ventilation and probabilistic explosion analysis for a large FPSO.
- Modelling for a North Sea Light Oil Platform – Smoke, ventilation and probabilistic explosion and dispersion analysis for a high pressure, high temperature light oil North Sea platform.
