Dr Fathi Tarada
BSc DPhil MBA LLB CEng FIMechE FIFireE FICE

The founder and managing director of Mosen Ltd is Dr Fathi Tarada. Fathi is a leading expert in fire safety engineering, tunnel ventilation and Computational Fluid Dynamics, with design, review and operations experience in buildings and infrastructure worldwide. He is the inventor of the MoJet® tunnel ventilation system, and has submitted a dozen patent applications in the field of mechanical engineering. He was the project director for the mechanical and electrical design in the New Tyne Crossing, and undertook a quantitative fire risk assessment for that tunnel which led to a specification for the first fire suppression system within a road tunnel in the UK. Fathi has acted as a technical adviser to the Land Transport Authority of Singapore for a series of detailed fire suppression tests using low-pressure deluge systems.

Apart from mechanical and electrical design, Fathi has also provided advice on structural fire protection for a number of tunnels within the UK and internationally, including the Conwy Tunnel in North Wales. He is the lead reviewer for the tunnel ventilation and fire safety design of 44 stations within Singapore Metro. Fathi was an expert witness for the Buncefield incident, the largest peace-time fire and explosion that occurred in Europe. He has extensive management skills in engineering projects, with an emphasis on delivery to time, quality and budget.

Fathi is the recipient of the Institution of Civil Engineers’ Construction Health and Safety Medal. He is the UK Representative in the World Road Association (PIARC) Technical Committee on Road Tunnel Operations, the chairman of the Annual Tunnel Design & Construction Summit, the chairman of the Annual Safety and Fire Protection in Tunnels Conference, and the past chairman of BHR’s International Symposium on Aerodynamics, Ventilation and Fire in Tunnels.


Karl Else
BEng Mechanical Engineering (First class honours)

Karl is the engineering director of Mosen Ltd. After graduating from Brighton Polytechnic in 1989 with a degree in mechanical engineering, Karl became a consultant specialising in Computational Fluid Dynamics.  Starting his professional career in the Channel Tunnel design team, he developed his skills in the transport, mining and power sectors developing particular expertise in smoke control, industrial ventilation and condenser optimisation. During this time he worked with a wide range of clients in North and South America, Europe and Asia on site and as part of local design teams on the Delhi, Ankara and Copenhagen Metro systems and the Attiko Metro in Athens.

Following a period in New York working on smoke control in the Hoboken, 33rd Street and World Trade Center stations for the Port Authority of NY & NJ, Karl returned to work in the UK on the Heathrow Terminal 5 station and the Thameslink and Crossrail stations at Farringdon.

After working on the Holmesdale, Bell Common and Hatfield Tunnels as part of the M25 Sphere project he formed an advanced simulation team with the mission to promote CFD and other simulation technologies into areas where they had previously not been considered viable.

A passionate believer in the use of simulation throughout the design process from concept to completion Karl is keen to promote to engineers, developers and end users about the necessity of using advanced tools in increasingly challenging design environments.

Dr Zhixin Hu
BSc PhD AIFireE AIMechE

Zhixin has been involved with fire safety, combustion and risk assessment since he finished his PhD in 2008 from University of Maryland in USA. During his PhD study, he also went to NIST as part of a research program, and strengthened his knowledge on fire modelling and the Fire Dynamics Simulator (FDS). His industry experience with fire safety comes from working on major projects involving buildings, tunnels, train stations and car parks. He has a focus on fire/smoke modelling and analysis, and he also developed his knowledge on various UK and international fire standards (including the UK’s ADB, NFPA, BS9999 and BS7974).

Apart from his fire safety experience, Zhixin also worked in the oil & gas technical safety sector for more than four years, involved in various detailed studies on safety and risk assessment from fire, explosion, smoke and toxic gas dispersion that may present hazards to personnel and property for offshore platform, refineries and chemical plants.
