Fire and explosion safety 



The KFX™ technology of ComputIT stands out as the preferred tool for cost-effective solutions to fire and explosion safety problems. The ComputIT consultancy services are characterized by innovative and cost-effective solutions for fire and explosion safety, combustion, environment and flares, onshore and offshore.  


ComputIT offers consultancy services in the areas of fire and explosion safety, combustion, environment, and flares for a multitude of oil and gas platforms, FPSOs and onshore process plants.



Structural fire response– optimization of PFP

From a large number of studies the last 20 years, ComputIT has estimated the typical cost reduction for their clients to be about 70% by use of the KFX™-USFOS technology for optimized PFP design. This represents huge cost savings.



Explosion safety

Gas dispersion and gas explosion analysis are done as basis for design solutions or as parts of QRA´s. Advanced analysis includes structural response to explosion loads. As basis for the modeling Shell´s well recognized gas explosion simulator Exsim is integrated as a part of KFX™.


LNG safety problems

KFX™ is the only CFD tool that is designed to capture the entire series of events that may arise from an accidental release of LNG. This also includes the cryogenic effects. ComputIT specialists are running a number of LNG studies worldwide for enhanced safety at both onshore LNG plants and FLNG´s.


Use of water for mitigation and protection of equipment

Water can be used for protection of equipment and structures, and KFX™ is widely validated in large-scale tests for such problems. ComputIT deliver services for permanent or temporary solutions with respect to all kinds of deluge, monitors, curtain, mist systems etc.


Flare analysis

ComputIT services relate to design and optimization of flare stacks and flare tips. This includes for instance calculation of radiation loads and temperature response in objects of interest where radiation from flare and sun, radiation shielding and wind cooling are accounted for.  Ignition, start-up processes, soot problems etc are also analyzed.

Our services also cover environmental friendly technology for combustion devices as burners or flare tips, industrial aero dynamics, and CFD analysis for the maritime sector.



The CFD software KFX™-Exsim is commercialised by ComputIT.

Kameleon FireEx KFX® is recognized as the leading industrial CFD technology for simulation of flares, gas dispersion, fire development and fire mitigation in complex environments. KFX™ handles all kinds of hydrocarbon fires; jet fires, spray fires, pool fires, including also LNG. The simulations are 3D and transient, the geometry modeling is based on efficient CAD import facilities, and external wind conditions etc are accounted for. The important interaction between the combustion processes and the complex geometries that oil and gas processing plants represent, are physically well taken care of. Kfxincludes comprehensive post-processing capabilities, such as video presentations and various visualization techniques.

KFX™ features the well-known and well-validated Exsim gas explosion simulator that has been Shell´s preferred tool for explosion analyses the last 20 years.




ComputIT´s philosophy is to develop and apply scientifically based methods to solve industrial problems. Significant contributions have been made through this philosophy to improve safety in the industry, reduce the negative impacts on environment from the oil and gas activity, and increase economic efficiency savings through the use of advanced and accurate methods for design. Contract research is a major activity and continuously ongoing R&D programmes funded by the industry are being carried out.


The Eddy Dissipation Concept (EDC) by Professor Bjørn F. Magnussen of ComputIT/NTNU represents a major scientific contribution to combustion modelling and is implemented in most international CFD codes dealing with turbulent combustion. He has also been awarded the Statoil Research Price for major contributions to the Norwegian oil and gas industry.
