This course addresses multiple hazards associated with onshore and offshore LNG facilities including LNG release and dispersion, explosion modelling, cryogenic spills, prevention and mitigation, probabilistic risk assessments, legislation and accidents.

You will participate in practical case studies and demonstrations on the application of 3D modelling to LNG explosion safety are also included.

CMR Gexcon

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

Course Outline

Day 1

  • fundamentals of LNG – composition, cryogenic properties, hazards (cryogenic embrittlement, pool fire, flash fire, explosion) 
  • LNG historical accidents – Cleveland explosion, Skikda LNG liquefaction facility explosion, other minor incidents 
  • gas explosion basics – combustion mechanisms, fuel reactivity, positive feedback mechanism, importance of geometry, explosion tests 
  • LNG accident consequences models – potential leak sources, dispersion (liquid spills and flashing jet releases), pool fires, explosions, benefits of CFD 
  • prevention and mitigation – hazardous area classification, ventilation, choice of equipment, maintenance and procedures, inventory control, ESD, layout modification
  • cryogenic spill hazards and protection

Day 2

  • LNG safety regulations – NFPA 59A, EN 1473 
  • hazard assessment methodologies – deterministic versus probabilistic methods 
  • deterministic analyses – onshore liquefaction case studies (export and truck-loading facilities)
  • probabilistic analyses – onshore liquefaction case studies 
  • probabilistic analyses – floating LNG case studies (safety gaps, grated decks, layout examples)

Course presenters

Dr Filippo Gavelli, head of the dispersion consulting group, GexCon

Dr Gavelli is responsible for GexCon’s LNG safety consulting business worldwide. He specialises in the analysis of heat transfer and fluid flow phenomena, including multiphase flows and cryogenic fluids. He has over 10 years of engineering consulting experience and nearly 20 years of experience in computational fluid dynamics (CFD) modelling, using several research and commercial codes.

Dr Gavelli is the lead author of several gas dispersion and explosion safety-related papers and has been a regular contributor to LNG-related technical committees and expert panels for several years. He is a member of the GexCon docents group, which develops and delivers safety seminars to facility owners and operators, safety engineers, and regulatory agencies, on the hazards associated with gas explosions, dust explosions and LNG. He also applies his expertise to the investigation of fires and explosions. He investigated numerous residential fires involving electrically powered consumer products, as well as fires involving all major modes of transportation.

Dr Chris Coffey

Chris is a senior computational fluid dynamics (CFD) risk engineer for GexCon. He works in the civil defence and oil and gas industries using mathematical and computational modelling of atmospheric dispersion, explosion and structural response. Chris holds a PhD in Fluid Dynamics from Imperial College, London, and an Honors degree from University College, London, in Mathematics with Theoretical Physics. He is a Chartered Mathematician and is Studying for an MBA. Chris has authored many papers within his field of expertise.
