Identifying Smoke Plume Hazards

Identifying Smoke Plume Hazards

Imagine that there is a kerosene refueling station at an airport and upon the full-bore rupture of one of the loading hoses, kerosene is accidentally released as a liquid forming a spreading liquid spill. If there is a nearby ignition source, the liquid spill will ignite creating a pool fire. Another situation is, that there is a warehouse storing a…

CO2 Hazard Assessment

CO2 Hazard Assessment

Carbon Capture and Storage (CCS) or Carbon Capture, Usage and Storage (CCUS) has gone through several phases of research and investigation. The current focus is on energy transition, so-called ‘blue hydrogen’ where hydrogen is generated via SMR (Steam Methane Reforming) from methane and the CO2 is stored rather than released to the environment, and in the capture of CO2 from…

Providing protection against criminal gas attacks on ATM's

Providing protection against criminal gas attacks on ATM’s

Explosive attacks on ATMs (Automated Teller Machines) happen on a daily basis in many countries.  The criminals use an explosive gas (often a mixture of acetylene and oxygen) to access the cash cassettes in the ATM. The Lockpoint Gryphon is the only ATM physical protection device to have been successfully tested to withstand such gas attacks. Gexcon teamed with Lockpoint…

Validation in Shell FRED

Validation in Shell FRED

With a major new update to the software due to go live later this year, this is the first in a series of blogs examining how Shell FRED has been proven in a range of different environments. We start with the history behind FRED’s experimental basis, charting the science and technical advancements from the 1970s to the present day. Going…

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

Gexcon investigated the detonation of approximately 20-30 tonnes of ammonium nitrate at the West Fertilizer Company storage and distribution facility in West, Texas. 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…

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…
