UNDERWATER CLEARANCE MEASUREMENTS Ships under the regulations, it is necessary to measure the rudder clearances and the tail-end shaft wear down clearance measurements in order to ensure that they are seaworthy and safe for the cargo and the crew that mans it. If the ship observes vibrations, then most often the cause lies in the axis system. It may be due to excessive clearances, or misalignment of the axial systems or propeller defects and cannot be detected without specific measurements and controls, such as pitch unevenness, imbalance etc. If the reported vibrations are accompanied by overheating of the bearings, then the bearing should be replaced even if clearances are less than 2% of the diameter. During the underwater inspection BEVALDIA (Manager of the branches PSOMAKARA & GAMSRO), uses a two-way communication system between diver and surveyor and real-time monitoring (CCTV) in order to achieve the best possible results. The whole underwater inspection process is videotaped and photographed, then delivered to the client and the inspector on DVD along with a detailed written report.
