MILITARY SEALIFT COMMAND'S EXPERIENCES WITH MODERN MEDIUM SPEED DIESELS IN U.S. FLAG OPERATIONS
This paper describes propulsion plant characteristics of the Military Sealift Command Build and Charter program for 9 tankers. Two U.S. diesel engine manufacturers supplied the 7,000 hp geared medium speed main propulsion engines. Each tanker uses two engines on a combining reduction gear, driving a controllable reversible pitch propeller for a total installed power of 14,000 bhp. Some details of the experiences, economics and operating parameters covering utilization of such power plants are described as well as the subjective criticism of the author. The initial program considered the use of up to 3,500 sec redwood residual fuels for the main engines. However, fuel economics and supply considerations have dictated utilization of diesel fuels (DFM, U.S. Navy all purpose fuels or commercial grade Marine Diesel). The first of nine (9) tankers of this program entered service in August of 1974; the last was delivered August of 1975.
