摘要：	The Coast Guard is required by law to reduce its overall energy consumption and to minimize the use of petroleum fuel in all its facilities and platforms. The Coast Guard Headquarters sponsor, Office of Naval Engineering (G-SEN), requested testing and evaluation of an electronic engine speed pilot on a WMEC-270. The sponsor desired testing of a system that would optimize propeller pitch in addition to engine speed on a controllable pitch propeller, since this was the configuration of most of the Coast Guard's large cutters. A sea trial was performed from 24 through 26 August on the CGC TAMPA to test an electronic engine speed pilot (ESP) system under actual operating loads and sea conditions. A fuel savings of 10% was measured for the standard engine RPM/propeller pitch settings tested using the throttle and pitch automatic control mode. Some of the ESP features did not work and require more development, i.e., best speed and automatic throttle control modes. Measurements from an independent and highly accurate positive displacement fuel meter tracked well with the derived fuel from the ESP. A description of the electronic engine speed pilot system, data analysis, and recommendations are presented. In addition, a high-level fuel savings projection was performed.
