GASP (Gas Accumulation over Spreading Pools)

GASP is a pool spread and vaporisation model that has been developed in association with the UK Health and Safety Executive (HSE).

GASP’s capabilities include:

  • A unified model for wind driven vaporisation (evaporation) and boiling
  • Pool spreading over smooth land, rough land and deep water
  • Pool constraints (e.g. bunds)
  • Effects of different ambient conditions such as air temperature, wind speed, humidity and solar flux
  • Two-dimensional time-dependent heat conduction from the ground and convection from the atmosphere

GASP interfaces to ESR Technology’s gas dispersion model DRIFT for prediction of downwind effects.

Why choose GASP?

  • Developed for the UK HSE, the model has undergone extensive verification and validation testing
  • GASP is coded for speed and efficiency, producing reliable results in seconds
  • Features a comprehensive graphical user interface and the ability to batch run multiple input files
  • Highly customisable input and outputs. Includes support for user defined fluids, substrates, result tables and graphs.

Who uses GASP?

We have licensed GASP to a wide variety of organisations since its initial release in the 1990s.  Typical users include:

  • Safety and Risk Consultants
  • Regulators
  • Operators
  • Academic Institutions

Model Validation

GASP has been extensively tested and validated for use by the UK HSE including for liquid hydrogen and LNG releases:
