For most toxic and flammable gases release the industry depends heavily on gas detection systems that give alarms or trigger interlocking systems. These systems are in place to reduce the hazardous effects of these scenarios. An efficient gas detection system is therefore vital in managing risks related to toxic and flammable gas releases in your facilities both on- and offshore.

But do we know if and how fast these detector systems will react to a hazardous release? The British Health and Safety Executive published a report stating that only 30 % of all major gas leaks in the British sector were detected by a gas detection system. This makes you think about the effectiveness of a safety system which we rely upon to protect us against quite significant hazards.

To learn more about the performance of gas detection systems, we have developed a method to assess the performance of your detection system. This method is based on Computational Fluid Dynamic (CFD) dispersion simulations performed on a model of your facility. CFD is capable of simulating gas releases in a very accurate and time-dependent manner. Studies can be based on high-velocity gas leaks, evaporation of leaked condensate, diffusive releases or other sources. The results of these simulations will help determine the performance of your detection system and help you improve it.

Field of Studies

Verification of the installed detector system
Comparison of alternate detector layouts
Testing of different detector set points or voting schemes
Suggestion for new layout/ alarm criteria
