Gexcon AS is a world-leading company in the field of safety and risk management and advanced dispersion, explosion and fire modelling. Gexcon’s experience arises from detailed knowledge of explosion phenomena built up throughout years of extensive research projects, carrying out safety assessments, performing accident investigations and performing physical testing at the company's own dedicated facilities on the Norwegian island of Sotra outside Bergen. Gexcon has, over several decades, developed unique expertise in safety and risk management and today the company enjoys a leading and reputable position in its field.
Over the last 40 years, Gexcon has been involved in the investigation of many high profile accidents such as Buncefield, Piper Alpha, TWA 800, and the P-36 platform (Brazil). Leaders in the oil and gas industry and safety engineers at major hazard facilities have consistently sought the services of Gexcon over the past 40 years to provide them with the expertise to manage the risks of fire and gas explosions from flammable substances.
Gexcon develops, maintains and uses the industry standard software for modelling gas explosions; FLACS®. Gexcon also develops, maintains and uses the industry standard for modelling dust explosions, DESC.
Gexcon can assist you in identifying your hazards, understanding your risks and contribute to improving our clients’ safety performance. Gexcon believes in a tailor-made and individual approach for each client. Together with our clients we find the most optimal process to identify your needs and the best way to improve your company’s safety performance.
Headquartered in Bergen, Norway, Gexcon also has offices in Washington DC, Houston (USA), Perth (Australia), Ormskirk (UK), Jakarta (Indonesia), Dubai (Middle East), Shanghai (China) and Pune (India).
Gexcon – the leading global partner in dispersion, fire and explosion safety.
Safety first – for people and industrial facilities all over the world. For serveral decades, this has been the main focus of Gexcon's products, risk assessment services and research.
Since the beginnings of the oil industry in Norway in the 1970s, our experts have built and shared knowledge on how to prevent gas explosion accidents. Our powerful FLACS software has now become the world's leading explosion simulator. Gexcon aims at being a leading company within explosion and fire safety worldwide.
Within the offshore oil and gas industry, use of CFD tools has become an industry standard in risk assessment and safety studies. FLACS, developed by Gexcon, is the most used and accepted consequence model for such studies worldwide. Gexcon aims at maintaining this position and further increasing the use of FLACS in onshore studies, dispersion and explosion, as well as for CFD fire studies.
Gexcon's head office is located in Bergen, Norway, with subsidiaries in the USA, UK, Australia and Italy. Gexcon also cooperates with a network of sales representatives to distribute the FLACS software and service globally.
With the improved precision of prediction tools, our development focus shifted towards topics such as the modeling of gas dispersion and explosion of non-homogeneous gas clouds, and tests to validate more advanced CFD-based risk assessment methods. FLACS was developed to handle new areas of application, e.g. onshore dispersion, hydrogen safety, release of liquefied gases with pool spread and evaporation (e.g. LNG) and dust explosions. Large-scale experiments performed elsewhere are often used to validate FLACS. More efficient calculations have been achieved through parallellisation and development of incompressible solvers (dispersion) in FLACS. Ongoing modelling efforts include the development of a fire model and work to improve interfaces.

Gexcon's Products & Services
Gexcon's main products are the FLACS CFD consequence software and consulting services using FLACS. Gexcon also provides dust and gas explosion testing at our large-scale or small scale test sites as well as qualitative explosion safety assessments. FLACS has long been considered the world-leading CFD tool for gas explosion modelling. In October 2011, FLACS became the first CFD tool accepted by the US Department of Transportation to be used for LNG facility siting studies in the USA according to the NFPA 95A standard.
Gexcon's consultants strive to be the preferred provider of CFD consulting services for a range of studies, including:
- Quantitative explosion risk assessments
- Accident/incident investigations
- Various gas and dust explosion studies
- Layout optimisation with regards to explosion risk
- Predicting the effect of explosion mitigation
- Blast waves and control rooms
- Drag loads on piping
- Toxic gas dispersion
- Helideck studies
- LNG dispersion studies
- Gas detector optimisation
- ATEX/DSEAR equipment testing and certification
- Experimental contract research
- Dust explosion testing
The competence of the company is built on 35 years of focused research and consultancy in the parent company Christian Michelsen Research (CMR) which e.g. resulted in the renowned explosion simulator FLACS. Gexcon was established as a brand name in 1987, but the gas explosion consultancy services were only formally separated from CMR in 1998. In 2000 Gexcon took over all explosion safety activities from CMR.
