The SGT-400 is a gas turbine produced by Siemens. It has a compact gas generator and a two-stage power turbine, using the latest aerodynamics and combustion technologies. The turbine has a simple-cycle efficiency of nominally 35%. For industrial cogeneration, the high steam-raising capability of more than 27 tonnes per hour contributes towards achieving overall plant efficiencies of 80% or higher. In addition, the SGT-400's compact layout, on-site maintainability and inherent reliability make it an ideal gas turbine for the demanding oil and gas industry. The SGT-400 incorporates proven gas turbine technology, offering cost-effective power for a wide range of duties, including: Industrial Power Generation, Simple-cycle and combined-cycle power plants for base load, standby power and peak lopping, Cogeneration for industrial plants with high heat load and district heating schemes, Power Generation in the Oil and Gas Industry, Offshore: on oil platforms and FPSO (Floating Production, Storage & Offloading) vessels, Onshore: for oil field service, refinery application, emergency and standby power generation, Including highly efficient cogeneration solutions for oil and gas applications. The SGT-400 combines very high efficiency (nominal 35%) with excellent emissions performance, in a rugged industrial design. This makes it the ideal choice for a demanding oil and gas industry.
The SGT-400 is a twin‑shaft industrial gas turbine designed for power generation, cogeneration and oil‑&‑gas applications. It provides a nominal 12.90 MW(e) output, high simple‑cycle efficiency (≈35 %) and low emissions, making it suitable for both on‑shore and offshore installations.
Key features include a dual‑fuel Dry Low Emissions (DLE) combustion system, modular package design for easy maintenance, and a Siemens SIMATIC PLC‑based control system. The turbine offers a compact footprint (width 2.85 m, length 14.50 m) and a range of service and support options through Siemens’ global network of authorized service centers.
