the above-mentioned problems. CODAG WARP uses two diesel engines to drive two propellers in a combined diesel and diesel (CODAD) arrangement, i.e., both shafts can also be powered by any single engine, and a centerline water jet powered by a gas turbine. The idling water jet does not cause drag, and since its nozzle can be placed further aft and higher it does not affect the size of the propellers. CODAG-electric Another way to combine the two types of engines is to connect them to generators and drive the propellers electrically as in a diesel-electric. See Combined Diesel-Electric And Gas (CODLAG) and Integrated Electric Propulsion (IEP). This also permits propeller pods, with the propulsion motors being located inside the pods.
