The bow thrusters are devices, which make vessels manoeuvring much easier especially in the harbours or the straits with high intensity of the traffic vessels. The long-term exploitation of these devices causes damages, mainly for its propeller blades. The cavitation is the main cause of its damages. Technical condition of all thrusters components mainly taking into account blades are subjected to periodic inspection according to classification societies. In this article have been included examples of bad condition of the thruster blades caused by cavitation process or mechanical damages. These damages can be dangerous enough to turn off the device and make the vessel be out of exploitation. The thruster blades repairing are a very complicated and hazardous venture. The blades are large sized, unbalanced, heavy components and difficult to be mounted in lathes. The main aim of this work is to identify opportunities of thruster blades repair process. The article presents technological problems of blade regeneration with the lathe as a complicated solid, which causes very big problems with the setting axis the component. The thesis presents methods of attach propeller blades using the special handle and tusk lathes. Among others, research allowed defining operation rotating velocity, and other parameters related to mechanical regeneration. The researches have shown that presented method in practice allows for secure mechanical regeneration of blades thrusters.
