This paper contains summary of investigations and analyses performed by Institute of Environment Engi-neering Systems, Warsaw University of Technology, in the area of management of the wastes produced in the course of ship repair work on floating docks. During the investigations carried out in Gdynia NavalShipyard, were determined substances which qualitatively characterize selected wastes (in their original form as well as their water extracts), and amount of the wastes of basic groups, produced during floatingdock service and repair and modernization work carried out on it, was estimated. Recommendations for waste managing on floating docks are presented, including possible ways of utilization of the wastes aswell as their final usage (recovery and/or neutralization)
