Shipboard electrical consumption profile analysis

Abstract

Department of Navy energy consumption reduction goals have been established for afloat commands and shore installations in order to keep pace with the ever increasing demand and high cost of energy resources. This study examines electrical power consumption data for various Pacific Fleet ships berthed at Naval Station, San Diego, CA. during the period 1 Jan. 1990- 19 Jun 1991, in an effort to construct daily ship consumption profiles from averaged data. These daily profiles are compared for ships of the same class by means of graphical and statistical analysis in order to determine how well daily class profiles will be able to accurately estimate consumption and subsequent costs. Utility savings examples are also discussed with use of these profiles. Class and individual ship daily profiles are constructed from the analysis for the purpose of being useful as a budget forecasting tool for the U.S. Pacific Fleet Comptroller and also as means to examine ways to efficiently use electricity in the future.
