Design
operations are in demand at Fläkt Woods UK after winning its largest
ever single contract, the project worth more than €7 million is to
supply ventilation fans for the massive Marmaray tunnel rail project
in Turkey.
The contract will supply the air movement needs on one of the
world’s biggest transportation infrastructure schemes, the 13.6
kilometres (8.5 mi) Bosphorus crossing. It has been described as the
project of the century, and the tunnel will connect two continents
with the €1.9bn rail-tunnel running deep beneath the Bosphorus
Straits.
The tunnel consists of a series of earthquake-proofed immersed
tubes, assembled from 11 sections, each as long as 130 metres and
weighing up to 18,000 tons. These will be placed down to 60 metres
below sea level; making it will be the world's deepest undersea
immersed tunnel tube.
The Colchester Company is supplying a range from their
super-powerful Axial fans for eight shafts ventilating the new
crossing. Measuring up to 2.8 metres in diameter, the fans will be
capable of providing emergency ventilation in the worst-case
scenario – a fire on a freight train more than a kilometre long.
The specialist fans generate a relatively high velocity discharge of
air-flow through the tunnel. As the jet from the fan diffuses, it
transfers energy to the tunnel airflow and creates an increase in
static pressure, which causes air to flow as in any conventional
system.
Paul Wenden, the Company’s engineering and marketing director, said:
“We export half of what the Colchester factory produces, and our
ability to diversify, sourcing business in both the building and
infrastructure and industry markets, has helped us to find new
business and this contract is a great example of this.”
Additional underground stations will be constructed at 3 locations,
and 37 new above-ground stations will be rebuilt or refurbished.
Once it is operational, the new transport link is likely to attract
more than 1.5 million passengers using the tunnel per day.
