propulsion systems

Naval Engine


Combined diesel or gas ( CODOG ) is a type of propulsion system where for every propeller shaft there is one diesel engine for cruising speed and one geared gas turbine for high speed dashes.

Both types of engines are connected to the shaft with clutches, but only one system is driving the ship in contrast to CODAG-systems, which can use the combined power output of both.
