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.

Famous quotes containing the words separate and/or shafts:
“In the very midst of the crowd about this wreck, there were men with carts busily collecting the seaweed which the storm had cast up, and conveying it beyond the reach of the tide, though they were often obliged to separate fragments of clothing from it, and they might at any moment have found a human body under it. Drown who might, they did not forget that this weed was a valuable manure. This shipwreck had not produced a visible vibration in the fabric of society.”
—Henry David Thoreau (1817–1862)
“Marriage has, for its share, usefulness, justice, honour, and constancy; a stale but more durable pleasure. Love is grounded on pleasure alone, and it is indeed more gratifying to the senses, keener and more acute; a pleasure stirred and kept alive by difficulties. There must be a sting and a smart in it. It ceases to be love if it has no shafts and no fire.”
—Michel de Montaigne (1533–1592)
