Assessment of mitigation measures effectiveness for minimizing DOMINO type accident propagation effects in storage tanksFunded under: JRC-INDHAZ 2C
Evaluation of DOMINO chain developments of accidents in the process industries is of great importance during a safety study. Simple consequence models have been used in developing the DOMINO package, which is able to simulate accident evolution sequences. Various protective and mitigation measures may have a profound impact on the accident escalation. In this paper a rigorous modelling of an atmospheric storage tank is presented, taking into account design/construction characteristics (tank geometry, construction, tank spacing) and all possible safety features (safety valves, liquid pump out, water deluge systems, water curtains, fire walls, external cooling by fixed or mobile fire fighting appliances). Heat input arises from an adjacent storage tank being on fire. The time dependence of pressure and temperature of the tank and its content properties are calculated. The impact of various operational interventions or additional safety features can then be evaluated. The model is being implemented on a computer program and, after its validation using experimental data, it will be incorporated in the DOMINO package.
