Opis:
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.

Opis:
In the article below, we presented the possibility of „spin test“ method usage for medium rotational speed devices such as thrusters', which are used to enhance the maneuverability of maritime vessels. The reason for the analysis is the problem of eliminating the unwanted vibrations of thruster's propeller with commonly used methods. It is an innovative solution for accurate verification of the technical condition of screw propellers, which are the most common devices used as the propelling element of thrusters. In the introduction the possibility of thruster's diagnosis using „spin test“ has been described. Commonly used thrusters' and their working conditions were presented. In order to properly assess the technical condition of rotational speed devices, such as thrusters' propellers after their production or renovation it is vital to provide an additional diagnosis in the environment similar to working conditions. Secondly, the problem of spinning parts' vibration was described. „Spin test“ method presented here gives the ability of detailed analysis of spinning parts' vibration. The idea of a compact and easy to assemble station enabling to conduct such research has been shown. The station not only allows to measure the eigenfrequency of vanes' in normal mode and compare it with the previously calculated ones, but also enables material's endurance testing at speeds higher than nominal speed. Finally, we presented the range of using this method in different fields along with the benefits of ‘Spin Tests’.
