Implementation of Reliability Centered Maintenance Method on the Biosolar B35 Ship Fuel System

The Indonesian government has mandated the use of Biosolar B35 fuel starting from 1^st February 2023, introducing new challenges for ships operation in one of Indonesia’s shipping companies, PT ABC. The purpose of this research is to identify components that cause failures in the B35 fuel system and determine effective maintenance types using the Reliability Centered Maintenance (RCM) method. This research using a qualitative approach, involving FMECA analysis for failure identification and the development of preventive maintenance tasks. The result indicates that the critical components in the B35 ship fuel system include Transfer Pump, Heater, Separator, Filter, Booster Pump, and Fuel Injection Pump. Among these, the critical components with the highest risk are Separator, Filter, and Fuel Injection Pump. Out of 18 analyzed task list, Preventive Maintenance (PM) emerged as the primary strategy (50%), followed by Condition Monitoring (39%), and Failure Finding (11%).
