COURSE OVERVIEW

It is essential for fire safety and risk management personnel to understand the principles of fires and explosions in order to determine how fires start and spread, and how explosions occur. Expert knowledge of hazardous area classification is also vital to enabling proper selection and installation of equipment to be used safely in hazardous LNG environments.

This training course covers gas explosion hazards and other hazards encountered in LNG facilities. It addresses all aspects of hazards associated with vapor cloud explosions (VCEs): ignition processes, release and dispersion, explosion mechanisms, blast load, and modeling of all these aspects. In this Gas Explosion and Other Hazards of LNG Facilities training course, you will acquire comprehensive knowledge of the causes and properties of explosions, emphasizing those involving gases.

LEARNING OBJECTIVES

The aim of this training course is to provide the participants with the knowledge and skills to understand the various hazards of LNG Facilities and how to mitigate pro activate an emergency response to incidents.

At the end of the training course, delegates should achieve the following key learning outcomes:

  • Understand the basics and important parameters governing vapor cloud explosion (VCEs) and other known hazards
  • Be aware of release and accidents statistics and have knowledge of some important offshore accidents that have occurred
  • Understand the accident chain of events
  • Understand various preventive measures to reduce the occurrence of accidents and various mitigation and control techniques to reduce gas explosion consequences
  • Learn the various explosion modeling techniques that may be applied and understand the importance of using advanced 3D modeling for gas analysis
  • Learn the different gas explosion analyses methods and when they may be applied
  • Understand how gas explosion loads can be integrated with the responses of structures

TARGET AUDIENCE

This training course is suitable for a wide range of professionals involved in managing Hazards and Risk on LNG Facilities including:

  • Safety engineers
  • Managers and other personnel involved in the design, operation, or modification of an offshore oil and gas facility (platforms, FPSO`s, etc.)
  • Accident investigators
  • Representatives of governmental or public bodies involved in the development of offshore safety regulations
  • Anyone who would like to develop an understanding of hazards associated with LNG Facilities

TRAINING METHODOLOGY

This Gas Explosion Hazards of LNG Facilities training course will combine presentations with instructor-guided interactive discussions between participants relating to their individual interests. Practical exercises, video material, and case studies aiming at stimulating these discussions and providing maximum benefit to the participants will support the formal presentation sessions. Above all, the course leader will make extensive use of case examples and case studies of issues in which he has been personally involved.

Pre and Post-course assessments will be used to measure the effectiveness of this training and the pre and post skill and ability of participants.
