<b>Abstract.</b> Gas turbines for marine application have been widely used, despite the inconvenient of high fuel consumption at part load. Improvement of fuel consumption has been achieved with the use of other engine types, as diesel, relying on the gas turbine at high power demand. New cycles have been designed to improve part load performance. This paper deals with the ICR, intercooled, recuperated cycle, with variable geometry in the power turbine nozzle guide vane, and a possible control strategy to maximize the engine efficiency at part load, that is, to minimize its fuel consumption.
<b>Keywords.</b> Gas Turbines, Performance, Thermodynamic cycles, Intercooling, Reheat.
