Cost Benefit Analysis of Adjustable Speed Drives Aboard Arleigh Burke Class Destroyers

Abstract

As the U.S. Navy seeks new and innovative ways to maximize its return from a finite budget, an evaluation of its operational practices must be done, Electrical power consumption and fuel efficiency are major factors in the Total Operating Cost (TOC) of naval ships and systems. An evaluation of an alternative mean for delivering electrical power to motors and pumps was conducted with the understanding that principles of the findings could be applied to fans as well. Adjustable Speed Drives (ASD), AC induction motors, AC synchronous motors, centrifugal pumps, and positive displacement pumps were examined. The technical challenges associated with ASDs were explored. MATLAB was used to calculate the potential power savings to be gained by introducing ASD technology to the Firemain and Chilled Water Systems. MATLAB was also used to calculate fuel cost savings from reduced consumption of Shipboard power.
