Altair To Supply Korean Navy

Posted on December 16, 2005

Altair Filter Technology has won contracts to supply gas turbine air filtration systems to two new vessels for the Republic of Korea Navy. The first KDX III warship and two new LSFII hovercraft will be fitted with Altair’s gas turbine protection. The KDX III is a 7000-ton warship designed and built by Hyundai Heavy Industries. The LSFII is a high-speed hovercraft landing ship under design construction by Hanjin Heavy Industries and Construction Company. The orders are the first with the Republic of Korea Navy for Altair which is based in Alton, Hampshire, England.

The filtration packages for the KDX III ship will protect three Rolls-Royce AG9140RF (Allison 501) ship service gas turbine generator sets providing the vessel’s main electrical power system, and four General Electric LM2500 gas turbines used for propulsion. The filtration unit for both types of turbine will use Altair’s Neptune system, which is operational on naval and commercial vessels throughout the world. Silencing equipment, weather protection and ancillary systems will also be supplied in addition to the main filtration packages. Delivery is scheduled for June 2006 and the ship is due to enter in-service trials in 2008.

The two LSFII hovercrafts will each be powered by four Vericor ETF40B gas turbines driving the lift and propulsion fans. The space and weight constraints onboard pose further challenges to the design of the filter house, said Altair. A specially engineered Neptune system - with the addition of an automated spin-tube assembly to remove sand and dust from the incoming air - will be supplied.
