Utilities - Biogas Storage/Management

4 Square provided a preliminary COMAH applicability assessment for an existing and proposed gas holder / gas management system. Our analysis served to confirm that the site inventory did not fall within the terms of COMAH thereby alleviating the need for additional safety measures and controls.

In support of the COMAH applicability assessment 4 Square also provided blast wave modelling to define the scale of effects of the worst case explosion. This satisfied those aspects of DSEAR Regulation 6 requiring such assessment to be carried out.
