Fuel efficiency is a priority for the Chief of Naval Operations CNO, as stated in the CNOs Position Report 2014. While a number of fuel-saving measures have been implemented in recent years, the effects of operational transit speed on fuel consumption have not been adequately understood as a variable.Ships commanding officers use fuel-usage curves to determine the most efficient propulsion-plant speed. Fuel efficiency is typically gauged by maintaining a consistent optimal speed. Often there are combinations of speeds that are more efficient than a constant speed. The transit fuel planner, developed in the Naval Postgraduate Schools operations research department by Brown, Kline, Rosenthal, and Washburn in 2007, calculates speed combinations to achieve fuel savings for a given single ship. This thesis adds additional capacities based upon common principles.
