FT4000® SWIFTPAC® Gas Turbine Package
The FT4000® SWIFTPAC® unit is the world's largest-capacity aero-derivative gas turbine power supply package. The unit performs with a simple-cycle efficiency of 41% or higher and rated outputs of 70 to 140 MW. The FT4000 SWIFTPAC package has an optimal modular design, based on proven features of the FT8® gas turbine packages, that decreases site installation work.
Features
- Enables a start-up time of 10 minutes from cold start to full power with outstanding system stability
- High-performance, diversified operability based on the properties of independent-output turbines (free turbines)
- Reduced O&M cost and cost of ownership
- Quick engine change out affords high unit availability

Solution
・A system (FT4000®SWIFTPAC® 140) with two gas turbines in twin configuration driving one generator helps reduce the construction unit cost and installation area per output.
・Individual smaller HRSG/SCR recommended for each engine.
・The free turbine construction of the power turbine (PT) eliminates the need for reduction gears and helps reduce the capacity of the lubricating oil equipment while improving performance.
・No clutch is needed during synchronous condensing operation (control of system voltage by monitoring.)
