The US Navy's next generation LPD 17 Flight II Class amphibious transport dock ships are moving forward in Main Propulsion Diesel Engine (MPDE) efficiency by installing the common rail fuel injection system on the ship's Pielstick-Colt 2.5V Sequentially Turbocharged (STC) engine.

NAVSEA reducing LPD 17 Flight II Class lifecycle cost with new common rail fuel injection system

The US Navy's next generation LPD 17 Flight II Class amphibious transport dock ships are moving forward in Main Propulsion Diesel Engine (MPDE) efficiency by installing the common rail fuel injection system on the ship's Pielstick-Colt 2.5V Sequentially Turbocharged (STC) engine.

This technically advanced system replaces the existing mechanical fuel delivery system and is expected to yield significant lifecycle cost savings due to reduced fuel usage and maintenance costs.

“We made the right decision to incorporate reduced fuel consumption, reduced emissions, less maintenance, and improved reliability into our next generation of amphibious ships,” said Capt. Brian Metcalf, LPD 17 class program manager for Program Executive Office (PEO) Ships. “Innovation should be driven into all levels of design, and this is just one example of NAVSEA’s culture of affordability mission.”

The project began in 2015 with discussions between PEO Ships, NAVSEA’s engineering and ship lifecycle management directorates, and  Naval Surface Warfare Center Philadelphia Division (NSWCPD), who is serving as technical lead for the contract. Fairbanks Morse engineers collaborated with MAN Diesel and NSWCPD to develop the prototype, which was tested on a future USS Fort Lauderdale (LPD-28) engine.

Upon completion of testing, the common rail fuel injection components were removed, and the mechanical fuel injection components were re-installed and retested prior to shipment. Prototype testing on the factory engines demonstrated fuel savings across the Navy operating envelope, and an emission-reducing engine operating profile was also developed.

The future USS Richard M. McCool Jr. (LPD 29), currently under construction at Huntington Ingalls Industries Shipyard in Pascagoula, Mississippi, will be the first of many amphibious ships delivered to the Navy with common rail fuel injection MPDEs.

As one of the Defense Department’s largest acquisition organizations, PEO Ships is responsible for executing the development and procurement of all destroyers, amphibious ships, special mission and support ships, boats and craft.

Ingalls has built and delivered 11 San Antonio-class ships. The 11th, Portland (LPD 27), will be commissioned on April 21 in Portland, Oregon. The 12th, Fort Lauderdale, is under construction and is expected to launch in the first quarter of 2020. Preliminary work has begun on LPD 29, and the start of fabrication will take place later this year.

The San Antonio class is a major part of the US Navy’s 21st century amphibious assault force. The 684-foot-long, 105-foot-wide ships are used to embark and land Marines, their equipment and supplies ashore via air cushion or conventional landing craft and amphibious assault vehicles, augmented by helicopters or vertical takeoff and landing aircraft such as the MV-22 Osprey.
