Naval Surface Warfare Center (NSWC) Carderock Division researchers complete testing of bulb bows for DDG 51-class. Partnering with Program Executive Office (PEO) Ships and the Naval Sea Systems Command (NAVSEA) Fleet Readiness Research and Development Program, NSWCCD conducted testing as part of the Navy's overall initiatives to reduce fuel consumption. Located near the waterline, the bow bulb is an inverted tear drop shape that protrudes from the hull and is designed to reduce the ship's wave resistance. Specifically, the bow bulb creates a wave designed to interfere with the existing bow wave which reduces the amount of drag on the ship as well as fuel consumption and engine exhaust emissions.

Naval Architects and marine engineers from around the world gathered in Honolulu in September for the 11th International Conference on Fast Sea Transportation (FAST 2011). The four-day biannual symposium promoted world-wide cooperation among scientists and engineers involved with all aspects of the high-speed maritime industry. FAST 2011 was the Fast Foundation’s 20th anniversary. Kjell Holden of the Norwegian Univ. of Science and Technology and FAST International Standing Committee…

The U.S. Navy's Office of Naval Research (ONR) announced that two inventors at the Naval Surface Warfare Center's Carderock Division will receive the Vice Admiral Harold G. Bowen Award for Patented Inventions in a ceremony at ONR at 1:00 p.m. on May 21, 2003. Gabor Karafiath and Dominic Cusanelli won for leading-edge scientific research set forth in U.S. Patent #6,038,995. It's a combined wedge and flap geometry, relatively small extensions of the hull, reducing a ship's use of propulsive power turning the drive shaft, thereby reducing fuel consumption. Fuel savings as high as $17.8 million per year would also reduce fossil fuel emissions into the environment and save 420 thousand barrels of oil per year. The Navy plans to modify fleet ships and those constructed in the future.
