CODAG drive

Principle of a CODAG drive system

A CODAG drive (for Combined Diesel And Gas ) is a drive concept from shipbuilding in which diesel engines and gas turbines are switched together on the drive shaft (s). The first ships to be built with this system were the F120 -class frigates of the German Navy .

The advantage of a CODAG drive is the lower fuel consumption due to the drive diesel in connection with gas turbines that can be switched on at short notice for maximum speed. The disadvantage is the complicated design of the gearbox , since very different powers have to be processed at the same time (order of magnitude: diesel several thousand kW, gas turbines several ten thousand kW).

CODAG drives are often used in warship construction.
