All UGT marine gas turbines have the three-shaft design. All UGT marine gas turbines consist of a two-spool gas generator and a free power turbine. The two-spool gas generator comprises two axial flow compressors (a low-pressure compressor and a high-pressure one), rotated by two respective turbines, and a cannular combustor of a loop-shaped type. The power turbine is not linked to the gas generator kinematically and can have reversible and non-reversible versions with different speed and rotation direction. This design provides low life cost, high efficiency, and reliability in any load conditions – from idle run to full power, requires low maintenance and gives the opportunity to create propulsion plants according to the rigorous client requirements.
