Naval vessels cannot afford to lose critical systems following an impact. Brian Stanton, North America Engineering Lead at Parker Hannifin's Gas Turbine Division, talks about the extensive testing required for inlet filtration systems used on these ships.Inlet filtration used for critical ship systems, such as on the propulsion gas turbines, must pass rigorous testing prior to installation. These tests include a range of vibration and shock tests that simulate ship operation and…

New GE LM2500 Module for US Navy Frigates

GE’s Marine Solutions announced it has completed the acoustic attenuation and weight comparison testing between its new lightweight composite LM2500 gas turbine module and the steel enclosure. The results verified a 2,500-kilogram weight reduction and a significant improvement in noise attenuation—60 percent quieter—when compared to its steel predecessor. “The tests compared the noise and weight of the steel enclosure to the novel one piece composite design. Results verified that the new carbon fiber provides a significant reduction in the wall weight and noise, which is vital on weight- and size-constrained surface combatants,” said GE’s Brien Bolsinger, Vice President, General Manager, Evendale, Ohio.

Navy's SDT Ship Using Alternative Fuels

Self Defense Test Ship transiting on alternative fuels.

U.S. Navy's Self Defense Test Ship successfully transits on alternative fuel blend. The U.S. Navy successfully has concluded its largest demonstration of shipboard alternative fuel use with the successful arrival of the Self Defense Test Ship (SDTS) to Naval Surface Warfare Center Port Hueneme. The SDTS is a decommissioned Spruance-class destroyer ex-Paul F. Foster (EDD 964) reconfigured to provide the Navy an at-sea, remotely controlled, engineering test and evaluation platform without the risk to personnel or operational assets.

Northrop Grumman Awarded $114M for Materials

The U.S. Navy awarded a $114m contract modification to Northrop Grumman Corporation (NYSE:NOC) to provide long lead materials for the company's 30th DDG 51 class Aegis guided missile destroyer. The materials purchased will be used in the construction of DDG 114. In April 2009, the U.S. Navy announced Northrop Grumman would be awarded contracts for the first two destroyers in the DDG 51 program continuation. The company has delivered 26 of 28 ships, with two more ships currently under construction in Pascagoula. This award is a modification of a contract awarded in December 2009 when the U.S. Navy awarded $171m for long lead material purchases for DDG 113.

Propulsion: Gas Turbines: Keeping Fresh With Innovation

Keeping pace with the fast-evolving maritime industry is a mantra at GE Marine with its LM aeroderivative gas turbine line. Going forward, GE Marine will see its LM gas turbines applied in several novel and state-of-the-art military and commercial marine projects. One military application in particular — the Office of Naval Research's (ONR) new X-Craft (pictured left) high-speed catamaran — will use two LM2500 in a COmbined Diesel Or Gas turbine (CODOG) configuration with two MTU 16V 595 TE90 diesel engines with a corresponding gearbox and four waterjets. The propulsion system will enable the vessel to reach speeds of 50 knots. According to GE, the X-Craft will set the stage for the U.S. Navy's next generation of warship, the Littoral Combat Ship.
