Service for Gas Turbine SGT6-2000E (V84.2)
General Information
- Description
The SGT6-2000E is characterized by extremely good rapid startup properties, very high reliability and availability as well as lenient fuel quality requirements. Since 1989 over 75 units have been installed world-wide. Together the fleet has more than 4.300.000 EOH. This gas turbine underwent several design versions over this time.
Over the last years the worldwide demand for power has been growing continuously. Siemens anticipated and reacted to the needs of the market by further developing its simple and combined cycle power plant technologies for the SGT6-2000E and providing a full range of performance enhancements.
To maintain the competitiveness of your operating assets, we offer the latest technologies to enhance your operating plant performance, reliability, availability and flexibility.

One of the innovative solutions offered by Siemens Energy to help you improve your operating plant competitiveness and profitability are the Siemens innovative 3-dimensional blades and vanes for the turbine stages.
Siemens innovative 3-dimensional blades and vanes are characterized by an aerodynamic blade and vane design with optimal efficiency as well as ability for retrofitting during service life. This generation of turbine stages blades and vanes has a new, optimized aerodynamic airfoil designed with enhanced material, coatings, an improved cooling air path and a reduction of parasitic losses.
Siemens innovative 3-dimensional turbine blades and vanes can include the following benefits:
Turbine stages 1 and 2:
- Increased gas turbine power up to 1,9 MW *)
- Increased gas turbine efficiency up to 0,45%-pts.*)
- Reduced life cycle costs
- Compatible with the Siemens 41,000 EOH maintenance concept upgrade.
*) Actual results may vary
Siemens innovative 3-dimensional blades and vanes for the turbine stages modernization include the following new designed profiles and additional turbine parts:
Turbine stages 1 and 2:
- Turbine vane 1 (including riffle seals)
- Turbine blade 1
- Turbine vane 2 (including riffle seals and U-shaped seal ring segments)
- Turbine blade 2
- Cooling air throttle for vane 2
- Control optimization of corrected turbine outlet temperature.
The upgrade includes execution of the following field work:
- Machining of the turbine vane carrier in vane 2 section inserting the cooling air throttle.
Siemens innovative 3-dimensional blades and vanes can potentially be implemented in a row-by-row replacement. A major outage for the installation of this modernization is estimated. We offer a full range of field service capabilities to help you manage your maintenance and outage schedules.
Siemens Energy has successfully implemented the first set of the innovative 3-dimensional blades and vanes for turbine stages 1 and 2 in the SGT6-2000E (V84.2) gas turbine in March 2009 in the United States of America.
More than ten units of frame type SGT5-2000E (V94.2) have been retrofitted worldwide. **)
Examples include:
- Two units in Argentina
- One unit in Australia
- Five units in Belgium
- One unit in the Netherlands.
