DDG 1000: Milestone atU.S. Navy Test SIte Converteam in partnership with the U.S. Navy have successfully tested the DDG 1000?s high voltage Integrated Power System (IPS)(1) to full power at the Land Based Test Site located in Philadelphia, Pa. DDG 1000 is the first U.S. Navy surface combatant to leverage this technology?an all-electric architec- ture providing electric power for both propulsion and ship services. As the inte- grated power systems provider, Con- verteam is responsible for the entire program?s high voltage system design, commissioning and testing at the landbased test site.The test demonstrated full power oper- ations of the IPS, which is a major mile-stone prior to delivery of equipment to the ship. The technology tested involved one of two shipboard shaft lines; one main and one auxiliary gas turbine gen- erator set, all four high voltage switch- boards, harmonic filters, two of four shipboard electrical zones of the Inte-grated Fight Through Power (IFTP) con- version equipment, and one of the two propulsion tandem advanced induction motors with their associated variable speed drives. Of this scope, Converteam supplied systems integration knowhow and hardware which includes the propul- sion motors, variable speed drives, high voltage switchboards and harmonic fil- ters for the main and auxiliary turbine-generators. DDG 1000 will be a multi-mission surface combatant designed to fulfill long-range land attack require- ments. Armed with an array of weapons, DDG 1000 will provide offensive, dis- tributed and precision fires in support of forces ashore.August 2011www.marinelink.com 11Talleres Navales del Golfo Islote San Juan de Ulúa s/n91800, Veracruz, Ver.

After ana- lyzing the results of an onboard testwith of a newbuilding vessel, the com- pany confirmed that the new paint of- fers improvements in fuel efficiency, and will contribute to the reduction of CO2 emissions from its vessels. Friction between the hull and thewater accounts for the majority of re- sistance as a vessel moves through the water. Reducing friction drag is a very effective way to reduce CO2 emissions during vessel operation.

The ultra-smooth finish is designed to minimize friction drag between thehull and the water, improving fuel effi- ciency by 3-5% compared to an identi- cal vessel with a conventional hull coating. Called Seaflo Neo, the paint isalso low in VOCs, a source of air pollu- tion.MR Aug. 11 # 2 (10-17):MR Template 8/3/2011 9:44 AM Page 11
