DDG 1000 Completes Successful Integrated Power System (IPS) Test
DDG 1000 is the first U.S. Navy surface combatant with an all-electric integrated architecture for generating and distributing electric power for all the ship’s needs from propulsion to weapons and sensors and ship services.
The LBTS is a full-scale DDG 1000 IPS with one of the two shipboard shaft lines that will be installed aboard the USS Zumwalt (DDG 1000), now under construction at Bath Iron Works in Maine. The LBTS system includes one main and one auxiliary gas turbine generator sets, and all four of the high voltage switchboards. Also installed are two of four shipboard electrical zones of “Integrated Fight Through Power (IFTP)” conversion equipment, as well as one of the two propulsion tandem advanced induction motors with their variable control drives. IFTP automatically reconfigures the power distribution system if damaged.
"The Integrated Power System is a central component to the ship's design and capability," stated Capt. James Downey, the DDG 1000 program manager for Naval Sea System Command's Program Executive Office (PEO) Ships. "The land-based test program remains an integral part of our commitment to manage cost and technical risk. This successful test validates the years of effort under the Engineering Development Model program implemented to reduce risk throughout the program."
The LBTS is located at the Naval Surface Warfare Center, Carderock Division, Ship Systems Engineering Station (NSWCCD-SSES) in Philadelphia, located at the former Philadelphia naval Shipyard.
The next test, planned for early 2012, will integrate and test portions of the DDG 1000 Engineering Control System (ECS) software with IPS to verify software and hardware compatibility and interoperability, the Navy says.
DDG 1000 is a multi-mission surface combatant designed to fulfill long-range land attack requirements and optimized for littoral operations. The 14,500 ton ship will have a crew of less than 150, thanks to automation.
USS Zumwalt is more than 40 percent complete and scheduled to deliver in Fiscal Year (FY) 2014 with an initial operating capability in FY 2016. The Navy plans to build three ships in this class.
As one of the Defense Department's largest acquisition organizations, PEO Ships, an affiliated PEO of the Naval Sea Systems Command, is responsible for executing the development and procurement of all major surface combatants, amphibious ships, special mission and support ships, and special warfare craft.
