ANALISIS PENYEBAB MENURUNNYA KINERJA POMPA CARGO OIL PUMP DEMI MENUNJANG KELANCARAN BONGKAR MUAT DI KAPAL MT.KRASAK

Abstract

Cargo Oil Pump is an auxiliary machine on board a tanker that plays an important role in loading and unloading operations. Its performance greatly affects the smooth transfer of cargo between ship and shore. During sea practice on MT. Krasak, a problem was identified in the form of decreased Cargo Oil Pump pressure caused by bearing damage. After an overhaul, another problem was found, namely mechanical seal leakage, which reduced pump performance and disrupted loading and unloading activities.This study aims to identify the causes of these problems and determine appropriate solutions. A descriptive qualitative method was used, with data collected through observation, interviews, and documentation during sea practice on board. The results showed that bearing wear was caused by inadequate greasing and errors in the bearing heating process. Meanwhile, mechanical seal leakage was caused by excessive pump vibration and insufficient inspection and maintenance. Alternative solutions include providing optimal greasing, supervising bearing installation according to the manual book, carrying out scheduled inspections and maintenance based on the Planned Maintenance System (PMS), and ensuring adequate lubrication. These efforts are expected to maintain optimal Cargo Oil Pump performance and support smooth loading and unloading operations problìems.
