A study was made of a 20,000-SHP, single-screw, integrated gas turbine power plant. A regenerative, two-shaft gas turbine was selected for the main power plant after studying several different gas turbine cycles. The expected all-purpose fuel rate for the ship at design conditions of 20,000 SHP, 105 rpm, 75-F inlet temperature and using specification residual fuel is 0.496 lb/SHP hr. A mechanical drive transmission system was selected having a double-reduction gear and a controllable- and reversible-pitch propeller. An auxiliary steam system is used with steam generated by means of a heat-recovery boiler and supplemented by auxiliary hot gas generators. A gas turbine-generator set, mounted on the main deck, provides ships' standby electrical service and port electrical power requirements. This set also is arranged to utilize exhaust heat to provide heating services in port. The location of this set enables the engine room to be secured in port during idle conditions to facilitate maintenance. An attractive and significant potential of the gas turbine is the improvement in output and efficiency as the firing temperature is increased with advances in material and fuel technology.
