CFD Gas Dispersion and Explosion Analysis

Get in touch


Helping you gain a deeper understanding of your hazards

ESR Technology offers comprehensive CFD (Computational Fluid Dynamics) services using FLACS from Gexcon, one of the industry’s premier CFD models.

CFD analysis provides intricate insights essential for explosion, gas dispersion, and ventilation management for new designs or modifications. FLACS’ versatile features and parameters make it suitable for a wide range of applications, including both onshore and offshore facilities.

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
  • Gas Dispersion Analysis – Gas dispersion modelling for scenarios of interest and probabilistic analysis for explosion exceedance analysis
  • Smoke Dispersion Analysis – Smoke dispersion modelling to inform escape route impairment and muster arrangements
  • Explosion Exceedance Analysis – Informing blast design decisions using probabilistic explosion exceedance.
  • Explosion Loading Analysis – Providing input to structural design and design optimisation studies including determining Design Accident Loads (DALs).
