GasSim2 was launched in 2006.

The Environment Agency now expects gas risk assessments to be completed using GasSim2.

You are free to continue to use GasSim 1.5 under the terms of the GasSim 1.5 Licensing Agreement beyond the date of withdrawal of help desk support, although we recommend that all users convert to GasSim2.

The current version of GasSim is Version 2.0. Contact the Golder Associates
