Abstract:
The Cargo Oil Pump (COP) is a vital component in the loading and unloading process
on tanker vessels. It serves as the main equipment to transfer liquid cargo from ship
tanks to onshore facilities. However, in practical operations, frequent disruptions occur
due to damage in COP components, particularly in the mechanical seal and bearing. This
research aims to analyze the root causes of mechanical seal leakage and bearing failure
in the COP of MT. Griya Ambon, and to formulate effective maintenance solutions to
prevent operational delays.
This study employs a descriptive qualitative method with a case study approach. Data
were collected through direct observation during sea practice, interviews with engine
officers, and ship maintenance documentation. The analytical tools used are Root Cause
Analysis (RCA) and fishbone diagrams to identify key failure factors. The results show
that seal leakage is primarily caused by high operating temperatures and inadequate
lubrication, while bearing failure is attributed to excessive vibration, improper
installation, and lack of shaft temperature monitoring. These issues contribute to reduced
operational efficiency and increased maintenance costs.
As alternative solutions, this study recommends implementing standardized procedures
for bearing installation and lubrication, using lubricants according to specifications,
adding a cooling system in the pump room, and conducting regular monitoring of
temperature and vibration. These measures are expected to improve COP reliability and
ensure smooth cargo handling operations on board.
