Predicting Ship Fuel Consumption: Update.

Abstract

This report is concerned with the prediction of ship propulsion fuel consumption as a function of ship speed for U.S. Navy combatant and auxiliary ships. Prediction is based on fitting an analytic function to published ship class speed-fuel use data using nonlinear regression. The form of the analytic function fitted is motivated by the literature on ship powering and resistance. The report discusses data sources and data issues, and the impact of ship propulsion plant configuration on fuel use. The regression coefficients of the exponential function fitted, tabular numerical comparison of predicted and actual fuel use data, the standard error of the estimate, and plots of actual and fitted data are given for 22 classes of Navy ships.
