Gas Turbine SGT-300
Power Generation: (ISO) 7.90 MW(e) / Mechanical Drive: 8.2 MW
The SGT-300 gas turbine combines advanced technology with a rugged industrial design. The single-shaft version for power generation has a power output of 7.90 MW(e) and is available as a factory-assembled package. The 8.2 MW twin-shaft version is used as a mechanical drive. The SGT-300 is designed to operate on a wide range of gaseous and liquid fuels.
For industrial power generation, this proven gas turbine is particularly well suited to combined heat and power applications. The compact arrangement, its on-site maintainability and inherent reliability have made it the gas turbine of choice for the oil and gas industry.
Fields of Application
· Combined heat and power (CHP)
· Power generation for the oil and gas industry, on offshore platforms and FPSO (Floating Production Storage and Offloading) vessels
· Power generator for oil service and refinery applications
· Emergency and standby power generation
For mechanical drive applications, like compressor and pump drives in the oil and gas industry, a twin-shaft version of the SGT-300 is used. It offers outstanding reliability, efficiency and maintainability and is designed to operate on a wide range of gaseous and liquid fuels. The SGT-300 can operate over a wide load and speed range providing the ideal drive solution for:
· Pumping applications including crude oil, other refinery product transmissions and water injection
· Compressor applications used in gas injection, pipeline transmission and boosting, gas processing and similar applications

Design
 Power Generation
The SGT-300 design is uniquely simple, employing a single twin-bearing rotor with heavy duty casings. This enables full site maintenance or quick core engine exchange. The gas turbine is available with a Dry Low Emissions (DLE) combustion system, providing high reliability, emissions levels to meet stringent requirements, and available for use on a wide range of fuels with common hardware.
Mechanical Drive
Building on the proven technology that underpins the rest of our gas turbine family, the mechanical drive variant builds on the proven reliability of the SGT-300. This machine utilises an identical compressor and combustion system from the power generation machine. Proven materials and technology are used in the 2 stage compressor turbine and 2 stage power turbine. This design approach ensures high reliability with good performance whilst retaining emissions and fuels capability. A modular design approach allows turbine module exchanges to be carried out in-situ as an alternative to a gas generator or power turbine service exchange.
