HEAVY DUTY GAS TURBINES-A VIABLE MARINE PROPULSION OPTION

Heavy-duty industrial gas turbines are suggested as an alternative propulsion plant to consider for ships, particularly ships of large displacement that are not volume limited. This paper examines the use of such a plant in a large Naval Auxiliary, the Fast Combat Support Ship (AOE-1, Sacramento Class). The cycle discussed is of the combined gas turbine and steam cycle. The inlet to the compressor is supercharged and then intercooled, allowing the gas turbine to perform at significantly higher than rated power levels. Two controllable pitch propellers at 50,000 SHP each are used to drive the ship. Exhaust from the turbine is used to generate steam in an unfired waste heat boiler. Reliability, maintainability, life cycle costs and manning are addressed for comparison with the presently installed steam plant.
