Uncertainty in explosion risk assessment

Uncertainty in explosion risk assessment

Offshore installations are threatened by various hazards which if not managed may lead to consequences such as injury or death of operators, damage to assets, environmental impact and business disruption. The main hazards include wind and waves, fires and explosions.  The topside of an offshore platform is exposed to the risk of hydrocarbon fires and explosions that unmanaged can lead…

Beirut port explosion: What we know from previous explosions caused by ammonium nitrate

Beirut port explosion: What we know from previous explosions caused by ammonium nitrate

According to reports on the BBC, the President of Lebanon, Michel Aoun said the blast was caused by 2,750 tonnes of ammonium nitrate stored unsafely in a warehouse. The Middle Eastern city of Beirut was shaken by the explosion and a large orange mushroom cloud could be seen spreading over the port area. This event has similarities to the Tianjin…

Geometry and Explosions

Geometry and Explosions

Geometry has long been identified as of key importance to understanding the consequence of explosions. Flame speed and explosion pressure strongly depends on the gas cloud and the geometrical conditions. Chris Coffey, Global FLACS Product & Strategic Business Development Manager, explains. Obstacle generated turbulence A number of large-scale gas-explosion experimental programmes took place in the 1980’s. One programme (GEP 80-86)…

Calculating Plume Rise Phenomenon with EFFECTS

Calculating Plume Rise Phenomenon with EFFECTS

Did you know that our consequence modelling software EFFECTS has a dedicated model to calculate the plume rise phenomenon due to warehouse or pool fires?     This model not only simulates the rising behavior of the hot smoke plume but also the effect of the penetration of the smoke plume through the temperature inversion layer or the reflection against…
