This report identifies U.S. Navy surface ships that would benefit most from the retrofit of hydrodynamic energy enhancement devices. These devices reduce be required power, and consequently, the fuel needed for propulsion. A large number of potential energy enhancement devices are assessed with regard to their suitability and cost effectiveness for retrofit to U.S. Navy surface ships. A powering evaluation of the U.S. Navy surface ship fleet was prepared. This information was used to identify eleven U.S. Navy surface ship classes as candidates for consideration with regard to retrofit of energy enhancement devices. These classes possess worthwhile energy savings potential with the installation of such devices. Potential yearly energy device fuel cost savings, and long and short term potential fuel savings, were then estimate for these identified candidate ship classes. A large number of energy enhancing concepts and devices with potential for reducing delivered power requirements or improving ship energy efficiency, are identified and described. A chart of compatibility between all identified energy savings devices was prepared. Over a dozen propulsion energy enhancement devices are identified as having potential for retrofit to U.S. Navy candidate surface ship classes. Recommendations are prepared with regard to which energy enhancement devices are to be considered as cost beneficial for retrofit to each of the eleven identified candidate U.S. Navy surface ship classes.
