Analysis of the occurrence of hydraulic oil leakage in the steering gear on the AHT Iron Tug ship
Keywords:

This study aims to analyze the cause of hydraulic oil leakage in the Steering Gear system of the AHT Iron Tug ship operated by Y&Y Maritime Management. Observation and data analysis showed a decrease in hydraulic pressure and decreased system responsiveness due to oil leakage in the worn seals and O-rings. Causative factors include excessive working pressure, mechanical vibration, use of substandard parts, and lack of regular maintenance. The ultrasound (Urgency, Seriousness, Growth) method is used to prioritize problems and show that seal damage, O-rings, as well as the use of non-standard spare parts are major issues with high impact. Repair recommendations include periodic replacement of components, strict supervision of the use of spare parts according to manuals, and improvement of maintenance programs. The results of this study are expected to help improve the reliability of the Steering Gear system and support the safety and efficiency of ship operations.
