The subject of this paper is a detailed qualitative analysis maneuvering and propulsion characteristics of a special purpose river vessel "KOZARA" River war flotillas of the Serbian Army, after reconstruction and modernization.

The subject of this paper is a detailed qualitative analysis maneuvering and propulsion characteristics of a special purpose river vessel "KOZARA" River war flotillas of the Serbian Army, after reconstruction and modernization. With the modernization of the ship, among other things, the old propulsion group with a classic diesel engine propulsion was replaced by a new diesel electric propulsion. In order to assess the justification of this replacement from the aspect of expected improvements of shunting and propulsion characteristics of the ship, it was necessary to develop and implement a test program and compare the results with available test results of the ship with the old propulsion group in earlier periods of ship operation. The results of measuring the basic maneuvering characteristics: ship speed, stopping distance and turning circle diameter, as well as propulsion characteristics: propeller shaft power, axial and torsional vibrations after six years of operation of the new propulsion confirmed all the advantages of diesel electric propulsion over classic diesel engine propulsion.
