This article focuses on the development of warship operating speed profiles by the U.S. Navy. Ship operating speed profiles define the time spent by a ship at each speed over an under way period. The expected operating speed profile drives numerous decisions affecting hull form and power systems. The U.S. Naval Sea Systems Command (NavSea) develops an annual Speed-Time Profile Guide for Surface Ships by using the past five years of Navy Energy Utilization Reporting System reports and applicable fuel data from ship energy conservation assist team reports. NavSea considers a speed time profile acceptable if it can be validated for use in calculating annual fuel consumption that agrees within 3% of the energy reporting system data.
