Atmospheric Dispersion Modelling Liaison Committee( ADMLC) webinar: Dense gas dispersion modelling in complex terrain

7 March 2023 @ 14:00 - 17:00

The Atmospheric Dispersion Modelling Liaison Committee( ADMLC) is holding a webinar on Tuesday 7 March 2023 at 14:00-17:00 (GMT) on ‘Dense gas dispersion modelling in complex terrain, with a focus on carbon dioxide pipelines’

The Net Zero agenda is currently driving a rapid growth internationally in Carbon Capture and Storage
(CCS) projects. These projects will involve transporting very significant volumes of captured carbon dioxide using cross country pipelines.

The aim of this ADMLC webinar is to bring together experts from the fields of atmospheric dispersion
modelling, field testing and pipeline risk assessment to share their thoughts on how best to tackle the
current issues, to discuss the pros and cons of different approaches, and to establish links between
groups of experts working on related topics. This includes model developers and users, test engineers
and agencies involved in risk assessment, emergency planning and incident response.
The webinar will follow a similar format to previous ADMLC webinars (see
with some introductory remarks to set the scene and six 20 minute talks, followed by a discussion
session, where active participation from the audience is encouraged. A list of the speakers is given

  • Simon Gant (HSE, UK and ADMLC chair) “Welcome and introduction to the webinar”
  • Max Kieba (PHMSA) “Introductory remarks and review of the Satartia CO2 pipeline incident”
  • Dan Allason, Ann Halford and Karen Warhurst (DNV, UK) “Carbon dioxide pipeline
    experiments and modelling”
  • Laurent Joubert (INERIS, France) “Experimental campaign of massive CO2 releases in
    urban areas”
  • Chris Dixon (Shell, UK) “Development of a shallow-layer model for dense-gas dispersion”
  • Sam Wang (Texas A&M, USA) “Determination of potential impact radius for CO2 pipelines
    using machine learning approach”
  • Mike Brown (Los Alamos National Laboratory, USA) “QUIC mountainous terrain and
    dense gas capabilities”
  • Ian Sykes (Xator Corporation) “SCIPUFF modelling of dense-gas dispersion”

The webinar will bring together representatives from industry, academia, government departments and consultancies, and provide an opportunity to share knowledge and experience in this field.

The webinar is free to attend and will be hosted on Microsoft Teams. If you would like to register for the event, please email:
