This wide-ranging course covers the basics of gas explosions, risks, prevention and mitigation. A major part of the course examines key statistics and analysis, explosion modelling techniques and lessons from previous accidents.

Specific hazards explored include vapour cloud explosions including ignition processes, release and dispersion, explosion mechanisms and blast loads.

CMR Gexcon

This course is offered in cooperation with GexCon, a world-leading supplier of software and services in the field of gas explosion safety.

Learning outcomes

  • understand the basics and important parameters governing vapour cloud explosions (VCEs)
  • be aware of offshore and LNG release and accident statistics and some important accidents
  • understand the accident chain of events and the important parameters affecting the gas release and dispersion
  • understand the various preventive measures to reduce the occurrence of accidents and the various mitigation and control techniques to reduce gas explosion consequences
  • learn the various explosion modelling techniques that may be applied and understand the importance of using advance 3D modelling for gas explosion analyses
  • learn the various gas explosion analyses methodologies and when they may be applied
  • understand how gas explosion loads can be integrated with the responses of structures
