Turbines and Diesels On Separate Shafts
Sometimes the engine arrangement of diesel engine and gas turbine with each system using its own shafts and propellers is also called CODAG. Such installations avoid the use of a complicated switching gearbox but have some disadvantages compared to real CODAG systems:
- Since more propellers have to be used, they have to be smaller and thus less efficient.
- The propellers of the idling systems cause drag.
