The fleet continues to demonstrate ease of operation and very high reliability and availability. It is a two-shaft, heavy-duty gas turbine designed for high operating efficiency over a wide range of speed and load conditions. This turbine is designed for mechanical drive applications such as gas boosting, gas injection/re-injection, pipelines, LNG plants and gas storage. It has a broad operating speed range to meet the requirements of the most common driven equipment (centrifugal compressors and pumps) as well as the ability to burn a large variety of gas and liquid fuels.
With simple and robust designs, complete maintenance can be performed on site without the need for specialized tooling or service shop assistance. The high-pressure shaft has a 16-stage, axial-flow compressor and a single-stage, high-energy turbine. First-stage nozzles are air cooled and second-stage nozzles are variable angle type. The low-pressure shaft is a single-stage, high-energy turbine. Twelve combustion chambers are contained within a single wrapper, a wide range of gaseous and liquid fuels can be burned, and a DLN combustion system is also available. A centralized lube oil system supplies clean, cooled, pressurized oil to lubricate the gas turbine and the driven equipment including the oil required for any compressor seals.
