Hazards Associated with Small-Scale LNG Installations

Training Period: 1 Day

Small-scale Liquefied Natural Gas (LNG) installations are getting more and more popular. They range from truck-filling stations to small-scale liquefaction plants. We offer an advanced course on the analysis of explosion and other hazards for small-scale LNG facilities. It addresses multiple hazards associated with LNG facilities, including LNG release and dispersion, explosion modelling, cryogenic spills, prevention and mitigation, probabilistic risk assessments, legislation, and accidents.

 

 

  • Understand the basics and important parameters governing LNG release and dispersion
  • Be aware of LNG release and accident statistics and some important LNG accidents
  • Understand the basics and important parameters governing Vapour Cloud Explosions (VCEs)
  • Understand the accident chain of events and the important parameters affecting the LNG release and dispersion
  • Understand various preventive measures to reduce the occurrence of accidents and various mitigation and control techniques to reduce explosion consequences
  • Learn the various explosion modelling techniques that may be applied and understand the importance of using advance 3D modelling for LNG explosion analyses
  • Practical case studies and demonstration on the application of 3D modelling to LNG explosion safety

 

 

Professionals who are concerned with the risks and vulnerabilities associated with the use of LNG on a small-scale.

  • Safety engineers
  • Safety consultants
  • Structural and design engineers
  • LNG process engineers
  • Investigation team leaders

 

 

In general, no special prerequisites are required. However, knowledge in process safety and experience in plant operation will be helpful.
