CODAG Water jet And Refined Propeller (WARP), a system developed by
Blohm+Voss as option for their
MEKO line of ships, also falls in this category, but avoids 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==
