A stern tube shaft and bearing metals are basically surveyed every five years by a surveyor. But, it is a very dangerous work and also requires so much time to a ship owner. In our experiences, regarding oil lubricated propeller shaft, over 80 percent of vessels were in the good lubricating conditions which the shafts and bearing metals were placed back to the original positions without any repairing work.<BR>Our research found that there was a strong relationship between the stern tube oil analysis results (especially on the wear metal debris) and the shaft/bearing metal survey results. When we could set up a stern tube oil condemning limits, International Association of Classification Society (IACS) announced the acceptance of NDI for the stern tube by an oil analysis. This paper reports that the Time-based Survey can be replaced the Condition Monitoring-based Survey on the oil lubricated propeller shaft and bearing.
