ANALISIS TERJADINYA KERUSAKAN PADA CARGO OIL PUMP DI KAPAL MT. GRIYA ENIM

Abstract

Yudha Al Zikri, Muhammad. 2025. "Analysis of Damage Occurrence on the Cargo Oil Pump on MT. GRIYA ENIM." The operational efficiency of oil tankers heavily depends on the performance of the cargo handling system, particularly the Cargo Oil Pump (COP), which plays a vital role during loading and unloading operations. This research was motivated by repeated failures observed in the COP system aboard MT. Griya Enim during the author’s sea project, which led to delays and potential economic losses. The main focus of this study is to analyze the causes of COP failures, their impact on operational efficiency, and propose effective maintenance strategies. This study employs a qualitative descriptive method with a case study approach. Data were collected through direct observation, interviews with ship crew members, and technical documentation. The results identified three primary causes of COP failures: leakage in the mechanical seal due to excessive vibration and insufficient lubrication; bearing damage caused by irregular lubrication, contamination, and shaft misalignment; and overheating of the electromotor resulting from the absence of an active cooling system and faulty temperature sensors. The impact of COP failures includes delayed discharge operations, disrupted sailing schedules, and increased operational risks. Recommended strategies include routine monitoring of temperature and vibration, scheduled lubrication, preventive component replacement, enhancement of the cooling system, and regular calibration of temperature sensors. This study concludes that structured maintenance programs and improved crew technical awareness are essential to ensure COP reliability and enhance overall ship efficiency.
