MGT6000 Doppelwelle

Benefi ts at a glance

– Modular design for easy

and fast installation

– High effi ciency

– Low emissions

– Low operating costs

– Low life cycle costs

Typical applications

Twin shaft gas turbines have a

variable speed drive shaft which is

the best and most effi cient way not

only to control fl ow or discharge

pressure, but also to start a

mechanical drive train. Driven units

are compressors and pumps for

pressure increase and transport of

gaseous and liquid media.

Typical application fi elds are

midstream and upstream oil & gas

production sites operating mainly

in simple cycle mode.

Gas turbines of twin shaft design are

also used for power generation at

fi xed speed. Selection criteria in such

cases are e.g. the package design or

driver communality in combination

with mechanical drive units.
