SGT-100 gas turbine


Engineered for demanding applications

The SGT-100 industrial gas turbine is a proven unit for all electrical power generation and mechanical drive applications.

The compact arrangement, on-site or off-site maintainability, and inherent reliability make it an ideal gas turbine for the demanding oil and gas industry. The gas turbine has a rugged industrial design that enables high efficiency and excellent emissions performance on a wide range of gaseous and liquid fuels.

SGT-100 gas turbine highlights

With the SGT-100 your plant will benefit from world-class availability in addition to maximum operational flexibility. The standard Dry Low Emissions (DLE) combustion system can operate on both liquid and gaseous fuels with low levels of NOₓ and CO emissions. At the same time, it allows for full load acceptance and shedding with automatic fuel changeover – without affecting turbine operation.

The SGT-100 has been used by the oil and gas industry since 1992. Many operating hours in both power generation and mechancial drive applications have provided oil and gas operators with the reliable operation expected in this demanding industry.

The SGT-100 has units operating in a wide range of ambient conditions: from extreme cold to hot and humid through to hot and dusty. The SGT-100 package design offers several standard options to cater for these wide variations in ambient conditions.

Our SGT-100 gas turbine is available with a Dry Low Emissions (DLE) combustion system, a modern approach that avoids injected diluents and addresses the production of low  NOₓ with a proven design. You will benefit from extremely low NOₓ emission levels with both gas and liquid fuels, as this gas turbine offers dual-fuel capability.

With its rugged industrial design and lightweight core engine, the SGT-100 is easy to maintain. You will benefit from minimal downtime and maximum availability thanks to long service intervals combined with rapid core engine exchange capability. An on-site maintenance option is available if you wish. Our industrial gas turbines are characterized by a long service life.

  • Simple and combined cycle power plants including cogeneration
  • Power generation for the oil and gas industry both onshore and offshore
  • Pump drive solutions for crude oil processing and transportation of refinery products
  • Compressor drive solution for natural gas processing

Ingenious design to the core

The SGT-100 features a 10-stage axial flow transonic compressor incorporating the latest aerodynamic technologies. The robust design gives optimized performance over a wide range of operating conditions. For power generation, the single-shaft design has a 2-stage turbine. For mechanical drive, the twin-shaft design has a single compressor turbine stage with a 2-stage free power turbine. The overall design of the gas turbine is uniquely simple.

SGT-100 packages

The health and safety of the operation and maintenance staff are paramount. This is why our SGT-100 packages are designed with a special emphasis on, e.g., walkways and handrails, noise suppression, access doorways, and safety interlocks.

The SGT-100 packages are compact and easy to transport, install and maintain.
The package includes the gas turbine, the gearbox, the driven unit and all fluid modules, mounted on a base frame. The factory-tested and certified fluid system modules come fully wired into the package's control systems.

Comprehensive services to support you

Our comprehensive portfolio of services provides low life cycle cost and optimum performance throughout the turbine’s life cycle: Long Term Programs (LTP), overhaul service, field service, spare parts, service exchange, remote diagnostic service, and modernization and upgrades.
Whether for scheduled service or short-term support, our specialists are there for you, on-site all over the world.
The SGT-100 package is designed for easy maintenance: Large side doors offer easy equipment access and facilitate changing the core engine. When your gas turbine is serviced, you can opt for exchanging the core engine for a replacement or on-site maintenance. The package includes on-site maintenance lifting beams.

Axial blade attachment

The first stage rotor blades can be axially removed for quick and easy in-situ changeout, maximizing availability.

Easy combustor maintenance

Combustion pressure casings split for easy access to the combustion hardware

Maximum fuel capability with minimum environmental impact

Fuel package

The SGT-100 offers a dual-fuel capability for all applications and can be operated with a range of gaseous and liquid fuels. It is designed to meet your individual operating criteria including reliable starting and changeover between fuels. The automatic changeover from the primary to the secondary fuel can be executed at any load. 

The engine has a hydrogen (H2) capability of up to 30 vol% (with DLE burners), or up to 65% (with diffusion burners with unabated NOx emissions).
