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 past chairman of BHR’s International Symposium on Aerodynamics, Ventilation and Fire in Tunnels, the past chairman of the Fire Protection and Safety in Tunnels Conference, and the past chairman of the Middle East FireSafe Conference.


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.

Nicole Hoffmann

Dr Nicole Hoffmann
BSc PhD CMath CEng FIMA FIFireE

Nicole is the director of fire safety engineering at Mosen Ltd. She has been involved in the fire safety industry for 30 years, starting with research at the Fire Research Station and the University of Greenwich, and more than 18 years directly as a fire engineer. Her work at the Fire Research Station kindled her interest in CFD smoke simulations which led her to obtain a PhD for her research into CFD modelling of fire and sprinkler interaction from the University of Greenwich. Her smoke modelling expertise became a stepping stone for her interest into human behaviour, and the start of the original development of the evacuation modelling package STEPS.

Since then, she has been involved in developing fire safety strategies, both in the UK as well as internationally. Working mainly within the transport industry, she has been involved in projects ranging from the King’s Cross LU station, Reading station, Crossrail, HS2 and the Northern Hub in the UK, to the 2nd Avenue Subway in New York and a high speed rail tunnel in Hong Kong; along with other buildings such as offices, hospitals, museums, schools and universities.
