ANALISIS KERUSAKAN PADA CARGO OIL PUMP (COP) UNTUK KELANCARAN BONGKAR MUATAN DI MT. GRIYA AMBON

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.
