We have successfully addressed some of the most complex challenges in fire safety engineering, to deliver cost-effective and acceptable solutions to our clients. Using both prescriptive and performance-based approaches, we are able to formulate holistic fire safety strategies for complex buildings and infrastructure
We are world leaders in the design of ventilation systems for rail, road, metro and utility tunnels. Our renowned expertise is underlined by our wide range of international projects, our involvement in standards-setting bodies including PIARC and our research and development activities
We have extensive experience of delivering high-quality CFD computations for a range of industries and applications including tunnel and station infrastructure, waste-water processing and data centre cooling. Our calculations benefit from consideration of best practice standards promulgated by international bodies, and experience in the writing of CFD codes
We have advised a wide range of clients in the management of risks, and can offer a number of professional services to support intelligent decision-making for the whole risk control cycle. This includes economic assessments of the likely benefit to cost ratios of alternative investments to enhance safety
Mosen Ltd has patented the unique MoJet® tunnel ventilation system, which has been adopted in a number of metro and road tunnels worldwide. This patented device can significantly enhance the aerodynamic thrust delivered by jetfans. It does this by using shaped nozzles to accelerate the flow and turn it away from the tunnel soffit and walls, thus reducing friction between the jet and the tunnel surfaces. The reduction in aerodynamic friction leads to significantly improved energy efficiency, as well as fewer jetfans being required to provide tunnel ventilation.
In the wake of the firebomb attack on Tsim Sha Tsui station in Hong Kong MTR which left at least 18 passengers injured, New Civil Engineer magazine has published an article about the incident, which calls for a design rethink.
