Qatar is to build the New Doha International Airport (NDIA) using Eight 36″ nominal bore reactive / absorptive exhaust silencers along with all ancillary fittings and full support structures for use in conjunction with Caterpillar 3516 engines at the airport.
The airport will be constructed 4km from the existing facility, on a 5,400-acre site. It is being constructed in response to a projected demand for additional international passenger capacity to the region. The current airport handles 4.2 million passengers per year, whereas the new airport will be able to handle 12.5 million per year after the first phase of construction. The first phase will cost $2.5 billion, while phases two and three are projected to cost an additional $5 billion.
The exhaust silencers have been exclusively designed around the airports abstract design without affecting the most important criteria being that of performance. Each silencer is manufactured throughout from Mild Steel, finished in a shot blast, hot metal spray then silicone sealed for extended operational life.
