Standardization and Preliminary Fuel Economy Trails of USS TARAWA (LHA 1)

Abstract

This report contains the results of standardization trials conducted on USS TARAWA (LHA 1) at a heavy displacement of 39,400 tons salt water (40,030 metric tons), and a light displacement of 35,000 tons salt water (35,560 metric tons). Measurements were made to determine powering data throughout the speed range at both displacements. In addition, fuel economy trials were conducted at the heavy displacement, and preliminary data are included in this report. TARAWA obtained a speed of 24.70 knots at 175.0 RPM, 2,010,000 pound feet (2, 730,000 newton metres) shaft torque, and 67,050 SHP (50,000 kilowatts) at heavy displacement. A speed of 25.42 knots was obtained at 174.7 RPM, 1,925,000 pound feet (2,610,000 newton metres) shaft torque, and 64,000 SHP (47, 750 kilowatts) at the light displacement. Preliminary fuel economy data indicate a Specific Fuel Rate of .647 pounds per shaft horsepower hour (.394 grams per watt hour) at 68,293 SHP (50,926 kilowatts).
