CODOG drive

Scheme of a CODOG drive

A CODOG drive (for Combined Diesel Or Gas ) is a ship propulsion concept in which diesel engines for cruising or gas turbines for maximum speed can be switched to the drive shaft.

The advantage of the CODOG drive is the relatively simple design of the main gear. One disadvantage is the additional weight of the drive component that is not in operation. Earlier CODOG drives often suffered from being susceptible to failure when switching between diesel and turbine operation. This problem has been eliminated in modern drives of this type.

CODOG drives are used in particular in warship construction.
