Joint Optimization Of Maintenance and Reliability on Pedestal Crane Units to Improve Operational EfficiencyPages 186-196
Abstract:
This research evaluates the maintenance and reliability of pedestal cranes in the Indonesian oil and gas industry, which is heavily affected by the harsh marine environment. The main objective is to improve operational efficiency through appropriate maintenance strategies. Based on operational data from January 2023 to October 2024, the initial reliability of the crane only reached 36.79%, with an MTBF of 272.89 hours. After implementing a lognormal distribution-based maintenance strategy, reliability increased to 42.88%, and Availability increased from 91.78% to 91.84%. This research identified the hydraulic system, running gear, and engine as the systems or components with the highest failure rates, accounting for more than 85% of the total downtime. Implementing a preventive maintenance strategy focused on critical components successfully reduced the MTTR from 24.44 hours to 24.25 hours. These results show a significant improvement in reducing downtime and extending the operational life of the crane.
