Repair and Maintenance of Hoisting Cranes Supporting MV. Pacific Bulk Main Engine Overhaul

Abstract

Disruption to the hoist crane can cause delays in repairs and even potential work accidents. On the MV. Pacific Bulk, the hoist crane was damaged, causing it to be unable to lift the load according to the expected capacity and hampering the main engine cylinder liner overhaul process. This research aims to identify the causes of damage, its impact on ship operations, as well as effective repair strategies to improve safety and operational efficiency on board ships. The research method used is qualitative. Data collection techniques through observation, interviews, documentation and literature study. The data analysis technique used in this research is the Root Cause Analysis method with a 5 why approach. Data validity testing uses the triangulation method. The research results showed that the hoist crane damage to the MV. Pacific Bulk is caused by several main factors, such as excessive vibration due to worn bearings, harsh sounds due to hard clutch rubber, and the inability to lift workloads due to wear of the reduction gear. Based on these findings, repair efforts include replacing bearings and clutch rubber, as well as routine maintenance and lubrication of the reduction gear. This implementation is to minimize operational disruption and improve work safety so that the cylinder liner overhaul process can run smoothly and optimally in the future.
