Blast and Fragmentation

shutterstock_1526062-copyIf there is a major incident or to help plan against the effects of an accident, then the effects of the blast wave and any resulting fragments that are travelling at high speed in its train are extremely important to understand as they may potentially have a devastating effect on people, buildings, assets, operations, environment, business, markets and your organisation as a whole.

Blast and fragmentation loads usually originate from a sudden release or conversation of a substantial amount of energy which can either be originated from an unwanted (accidental or malicious/terrorism) or intentional (as part of a process) origin or location. HazRes has studied origin causes such as confined and unconfined vapour cloud explosions and detonations, rapid phase transitions (molten metal and cryogenic liquids into water), bursting pressures vessels, vented explosions, high explosives, enhanced explosives, two phase explosions/detonations, dust explosion and detonations, and conventional and unconventional weapons to mentioned a few.

It is also important to characterise a potential blast wave and its interaction with people and structures including buildings, equipment, process units, rigs as well as other protection and mitigation devices such as bunkers, shelters, barriers, earth berms and blast attenuation devices for example. HazRes has the ability to predict and analysis blast wave effects and their interactions, not only with structures and the environment, but with themselves through reflections, refractions and focusing which in turn may potentially increase their damage severity relating to a structure.

HazRes has experience not only designing protection and mitigation devices for military, commercial and civilian use, but has the ability to analyses the effectiveness of any preinstalled devices or methods as well as to provide upgrade designs for structures in order to meet new identified threats and hazards.

HazRes uses a number of predictive models ranging from vapour cloud explosion (VCE), high explosive (HE) and bursting pressures vessel (BPV) blast wave prediction methodologies to sophisticated implicit and explicit based computational fluid dynamics (CFD) and coupled Finite Element Analysis (FEA) codes to model fluid-structure (FSI) and blast-structure interactions (BSI) and a combination to provide our clients with the most adaptive modelling solution for their needs.
