Abstract

The main engine lubrication system on a ship serves to protect moving components. If this system does not work optimally, main engine performance will decrease, damage will occur faster, and maintenance and operational costs will increase. Therefore, it is important to analyze the damage of lubrication system components as a preventive measure, reduce the risk of failure, and support long-term strategic planning. This research aims to analyze the function, functional failure, and failure mode of the main engine lubrication system components using the Fault Tree Analysis and Failure Mode and Effect Analysis methods. The optimal maintenance strategy is determined based on the Reliability Centered Maintenance II method, and long-term cost efficiency is calculated using the Life Cycle Cost Analysis approach. RCM II results show LO. Purifier as a critical component, with an RPN value of 288, and the fastest initial maintenance interval compared to other components. The reliability value of LO. Purifier reliability value of 0.618 at t = 300 hours, with a schedule restorating task at 179.433 hours. The results of the cost analysis show that the lowest total cost was reached in the 11th year, namely IDR 117,998,457.55 (2 mechanics) and IDR 130,606,050.61 (4 mechanics). This indicates that the optimal economic life of the lubrication system is 11 years, before considering replacement or rejuvenation.
