CODAG Water jet And Refined Propeller (WARP), a system developed by Blohm+Voss as option for their MEKO line of ships. 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.
