The reasons, reconstruction and some characteristics of the special purpose river ship BPN-30 "Kozara" are presented in this paper. The ship is equipped with two diesel aggregate power of 400 kW each, which drive two electric motors power of 250 kW each, bow thruster power of 90kW and supply ship electrical grid with power of 90 kW. Main diesel electric generators can operate independently or in parallel operation. On board the auxiliary diesel aggregate is set to supply the ship with electricity with the power of 70 kW while on shore connection. The performed testing of the ship show a significant improvement of the manoeuvring and propulsion characteristics of the ship compared to conventional diesel-powered two engines, rated power 294,4 kW each. The paper outlines other advantages of the ship with electric propulsion as it increases in the comfort of the crew and downstream economical cruising with a single diesel engine in the operation. It can be concluded that the diesel electri...c drive shows a number of advantages for the operation of river ships that can be used for different drives of river ships.
