During the exploitation screw thruster, lobes are being defected in many ways. Sample types of damages are as follow: the material damages caused by cavitation, corrosion, deflection. In order to facilitate and to improve the quality of repairing activities, the idea of make the position to designate screw thruster lobes specific gravity has been initiated by Rolls-Royce Poland Company and Nautica Academic Circle. Incorrect lobes balance influences on irregular work of the screw, which results in the occurrence of adverse effects such as generation of vibration or increasing probability of mechanical elements damages during the exploitation. Screw thruster lobe specific gravity designation helps in identification of areas for treatment (welding, grinding) to achieve the desired parameters. The creation of designate screw thruster lobes specific gravity position gave the possibility of using the innovative scanning in 3D, which shows very clearly the picture of the scanning item. With Scanect and Autodesk Inventor 2014 software, we can manipulate the resulting image. This makes possibility of the lobes gabarits measurement. What is more, it designates the specific gravity exact to 10%.It increases the quality of the lobe renovation and these results in an improvement the screw thruster lobe’s work efficiency.The cooperation of The Maritime University in Gdynia and Rolls-Royce Poland Company resulted in creating the prototype, which will be tested by service technics in working circumstances.
