The Effects of Steaming on Ship Downtime and Fuel Consumption
Published Date: January 1, 1980
Regression analysis is used to estimate the effects of steaming on a ship's condition and fuel consumption. Equipment condition of destroyers, cruisers and frigates is measured with data from Casualty Reports (CASREPTs) that were made between Jan 1970 and Jul 1975. A separate analysis is undertaken of steaming's effects on each of three components of CASREPT downtime--CASREPT rate, supply time, and maintenance time. The effects of various factors besides steaming are also measured, including ship's fleet (Atlantic or Pacific), ship's class, and time since overhaul. Steaming's effects on diesel, JP5, and other fuel are estimated for each of 13 ship classes and also for the typical destroyer.
