Sécurité et Risques
Au fil des années, Fluidyn a acquis une expertise reconnue dans les domaines de la sécurité et de la maîtrise des risques industriels. Grâce à sa gamme de logiciels dédiés à la modélisation des conséquences, Fluidyn propose des services de simulation avancés pour évaluer les scénarios accidentels, aussi bien en environnement ouvert qu’en milieu confiné.
Forts de notre expérience, nos experts vous accompagnent à chaque étape de votre démarche de gestion des risques : identification des dangers de vos installations, modélisation précise et réaliste des conséquences d’accidents majeurs, analyse des risques, optimisation des périmètres de sécurité et amélioration des performances globales de votre politique de prévention.
S’appuyant sur un ensemble complet de solutions de simulation numérique 3D, nos consultants analysent vos problématiques en profondeur afin de vous proposer des solutions adaptées, fiables et innovantes pour renforcer la sécurité de vos installations et soutenir vos prises de décision.
Fluidyn vous accompagne dans les domaines suivants :
Modélisation des explosions (gaz et poussières)
Modélisation des incendies
Modélisation des ruptures de réservoirs et des pertes de confinement
Sécurité des procédés et analyse des risques de vos installations
Optimisation de l’implantation des capteurs
Analyse post-accidentelle par simulation numérique
Modélisation de la dispersion
Un grand nombre d’accidents industriels trouvent leur origine dans une fuite de gaz toxique ou inflammable dans l’atmosphère. La maîtrise de ces risques nécessite une évaluation précise de l’étendue du nuage de gaz généré par une fuite provenant d’un équipement industriel ou d’un réservoir de stockage, afin d’en analyser les effets aussi bien sur site qu’à l’extérieur du site.
Grâce à notre expertise en modélisation 3D de la dispersion dans des géométries complexes, nous vous accompagnons dans l’évaluation des conséquences dangereuses liées aux rejets de gaz toxiques et inflammables. Nos consultants hautement expérimentés vous proposent une approche adaptée à vos études de dispersion dans les domaines suivants :
- Dispersion de gaz inflammables
- Dispersion de gaz toxiques
- Dispersion de radionucléides
- Conception de mesures de sécurité et analyse de leur performances
- Optimisation de l’implantation des capteurs de gaz (fumées, gaz toxiques, gaz inflammables)
- Identification des fuites par modélisation inverse

Explosion modelling
Gas or dust explosion is one of the most critical accidents on a onshore plant or offshore facilities. Our consultancy team can help you in the consequence assessment of the overpressures caused by all kind of explosion scenarios in simple or more complex geometries. Our experience and knowledge in explosion modelling give you the opportunity to perform the following studies:
- Gas explosion and deflagration including hydrogen
- Solid explosive detonation
- Blast propagation
- Blast wave load on structure
- Dust explosion
- Influence of the ignition points
- Explosion mitigation measures design and ALARP analysis
- Accident investigations
Fire modelling
Fire modelling is used to assess the heat radiation and the spread of smoke from solid or liquid fires. Our experts with their knowledge of simulation tools can assess and improve the fire safety of your facilities and help you in the following fields:
- Flammable liquid, solid or jet fires simulation
- Fires of various natures (pools, rack, bulk, warehouses, offshore platforms, car parks, fires in buildings…)
- Structural integrity analysis for thermal load
- Smoke dispersion inside and outside buildings
- Toxicity and visibility assessment of smoke propagation
- Fire mitigation measures design
- Accident investigations

Tank rupture modelling
Tank rupture modelling is used to assess the overflow following a loss of containment through a catastrophic tank failure. Our modelling experts can assess the potential consequences of :
- Overspill of Flammable Liquids,
- Pool spreading inside the retention
- Liquid behaviour outside the retention and impacted areas,
- Pressure loads on retention bunds and walls,
- Structural integrity analysis of bunds and walls,
- Mitigation measures design (secondary confinement, wall shape, wave breaker, …)
- Accident investigations
Process safety and risk analysis
The risk assessment based on the prevailing regulations is done step by step from the potential hazard identification to the final risk analysis. The objective of the risk assessment of your facilities is to reduce and manage risk by including the operational safety to the environment protection without neglecting the cost aspects. Our high capability consultancy team can help you in your risk analysis from the hazardous inventory (HAZID) to the quantitative risk assessment (QRA).
- Hazard identification and analysis
- Consequence modelling
- Risk analysis (preliminary risk analysis, fault tree, bow tie, …)
- Quantitative risk assessment (QRA)
- Optimization of mitigation measures performance (fire walls, blast walls, toxic/flammable detection,…) by numerical modelling
Sensor network optimization
The gas sensor network is one of the most important safety features on an industrial plant. Ensuring that the network is well designed and efficient reduces greatly the major accidents related to toxic/flammable releases on your facilities. Our engineering team can help you in optimizing your sensor layout (location, number, specifications…) with an appropriate strategy based on dispersion modeling and inverse calculation for any kind of gas release in complex geometries.
- Optimization of sensor locations
- Performance analysis of an existing sensor network
- Improvement of the efficiency with new threshold alarm value
- Cost reduction by redundant sensor removing

Post accident analysis
Our consultants with high experience in accident modelling, ranging from toxic release to large fires and explosions, can assist plant owners and mandatory authorities in understanding the cause and consequences of major accidents.
Fluidyn can also be part of legal investigations providing our expertise. Based on the investigation of incident consequences, our team can perform simulations to identify the origin and the factors leading of the accident. With our consequence modelling expertise, we can assess accurately the fire products dispersion and the overpressure effects during the unfolding of the accident as well as the impacted surrounding areas. Theses investigations will give you new solutions to improve the risk management of your facilities.
