Siemens Energy - Model SGT-A35 - Aeroderivative Gas Turbine
A trusted choice, proven in critical operations. Simple cycle power generation (ISO) up to 37.2 MW(e). Mechanical drive: 38.5 MW. Qualified and proven in oil and gas applications, onshore and offshore.
Trusted power, everywhere
With class-leading reliability and availability, the SGT-A35 is your proven, dependable choice in power generation and mechanical drive applications. It is qualified to meet the stringent standards of the oil and gas industry and has earned a solid reputation in both onshore and offshore service.
The SGT-A35 fleet has matured over 46 million hours in service. This gas turbine variant is the latest evolution in a portfolio continuously improved over 40 years of technology development. Utilizing components already proven in industrial, marine and aerospace service, the SGT-A35 offers class-leading power density for power generation and mechanical drive applications. The efficient SGT-A35 gas turbine is integrated in a compact, lightweight and highly maintainable package designed for oil and gas applications.
Flexible application match
The SGT-A35 portfolio includes 2 variants of gas generators and 3 variants of free power turbines, allowing multiple combinations with power output ranging between 32 and 38 MW in mechanical drive, and different drive-shaft speed. Each variant is available with or without Dry Low Emissions (DLE) combustion and can be configured for electrical generation or mechanical drive, onshore or offshore. Such a diverse portfolio ensures that the gas turbine can be ideally matched to your requirements of each application.
Vast experience, trusted performance
The SGT-A35 has earned the trust of operators in a large spectrum of applications, in the power industry as well as in oil and gas. The SGT-A35 legacy spans over 40 years of continuous improvement through the incremental injection of aero engine technology. Over 850 SGT-A35 units have been sold to date, accumulating a service experience of over 46 million operating hours. The SGT-A35 is regarded as a class leader for reliability.
No “hot lock-out” periods
All variants of the SGT-A35 can be restarted at any time following a shutdown from any condition, without any delay due to "hot lockout" conditions. Unlike some of its competitors, the SGT-A35 can achieve this reliably by inherent design. Thanks to its agile twin-spool architecture, the SGT-A35 provides the most robust solution to restoring power quickly when its availability is most critical.
Evolved from proven components
The SGT-A35 is the latest evolution in the portfolio, introducing a synchronous speed variant to the existing highspeed power turbine coupled to the prove gas generator to allow direct drive or geared drive of an electrical generator.
The SGT-A35 can also be utilized in mechanical drive applications, making it one of the most flexible gas turbines in its range. Its performance is optimized for hot climates, delivering significantly more power at 30 °C than its predecessors.
Combining the best in the industry for oil and gas
The SGT-A35 brings to oil and gas operators the trusted technologies acquired by Siemens Energy aeroderivative gas turbine portfolio. The reliable SGT-A35 gas turbines, with over 800 units supporting oil and gas operations worldwide, are now packaged with the oil and gas expertise of Siemens Energy, which has supplied over 1,000 units to the oil and gas industry over the years.
