Consequence Modelling Techniques

Topic Safety

CPD Hours 11.5

Price IChemE member £1080 + VAT, non-member £1296 + VAT

Overview

Live online course – starts on 1 October 2020.

Consequence modelling is used to predict accident effects and impact on people, the environment and property. This online course draws upon loss-of-containment scenarios and guides you through a range of models, using workshops and case studies, to demonstrate different approaches to consequence modelling.

The course includes exercises on scenario definition, selection of input parameters, simple modelling and interpretation of results.

Teaching will be delivered via two live modules (approximately 2—3 hours in length each), alongside independent study and pre-recorded video sessions issued before/between modules. 

Learning outcomes

By the end of the course delegates will understand:

  • how to identify a set of major accident scenarios on a facility handling hazardous materials
  • which types of models available for different scenarios and which are appropriate at different stages of plant design or operation
  • the limitations of the various model types
  • how to define the possible outcomes of hazardous material release e.g fire, explosions and toxic effects
  • the requirements for modelling these hazards
  • the possible impact of hazards on people, the environment and property 
  • the importance of defining source terms (initial conditions), including uncertainty
  • how to specify a range of hazard studies and interpret the output
  • how to interpret model results and how they are used in quantified risk analysis
  • regulatory requirements for consequence modelling.

Who will benefit

  • Project and plant managers
  • Safety managers responsible for preparing safety reports and interpreting modelling results
  • Professionals using consequence models and/or their results and want further guidance on the bases, validity and uses of modelling
  • Those new to the field of process safety
  • Anyone would needs to understand the potential scale of accidents and the consequences

Course outline

  • Basic concepts and definitions
  • Consequences for modelling 
  • What is a model and when are they needed
  • Source terms and consequences for liquid vessels and pipes, gas vessels and pipes, flashing liquids, two phase vessels and pipes, and time dependency
  • Basic hazard identification methods
  • Dispersion models – passive/lighter than air, momentum jet, heavy gas and CFD techniques
  • Transition from source model to dispersion model
  • Interpretation of dispersion model results
  • Explosion modelling – VCE, confined, semi-confined, vessel burst and dust explosions
  • Fire modelling – pool, jet, fireballs and assumptions
  • Application of results – inputs to risk analysis, QRA, LOPA , emergency response plans, escape and evacuation
