U.S. Department of Defense Navy Shipboard Energy Conservation Team—"Outstanding Performance"
December 1, 2002
The Navy Shipboard Energy Conservation Team provides the Navy's fleets with new energy conserving technologies, conservation training, strategies, and awareness. The team increased steaming hours at no extra cost by managing fuel consumption and transit speeds and eliminating unproductive energy expenditures. In FY 2001, the team's work resulted in 38,000 hours of additional steaming or avoided energy costs of $41.7 million. This is equivalent to the fuel cost of operating 19 destroyers for an entire year. The team's work captured fuel savings of more than 1 million barrels of fuel oil, similar to removing 68,000 sport utility vehicles from the nation's roads for a year. Installation of stern flaps on 61 ships resulted in estimated savings of 203,000 barrels of fuel. When fully implemented (by 2005), the team's stern flap work alone will save 446,000 barrels of fuel, or $18 million annually.
The Navy's Pacific Fleet avoided costs of $25.5 million from 86 ships, and the Atlantic Fleet saved $16.2 million from 118 ships. Among these, the USS Blue Ridge, a command ship for the U.S. 7th fleet in Yokosuka, Japan, saved more than $2.25 million; the USS Kearsarge increased its steaming hours by 467 percent, reduced fuel consumption by 20 percent, and saved $1.75 million; the USS Cowpens, supporting Operation Noble Eagle in the war against terrorism, avoided costs of $923,000; and the USS Porter, despite increased threat conditions and increased assigned energy requirements, avoided costs of $444,000.
