ANALISIS DAMPAK KEGAGALAN SEAWATER PUMP TERHADAP EFISIENSI PENCUCIAN TANGKI MUATAN PALM OIL UNTUK MEMENUHI STANDAR KUALITAS WALL-WASH ANILINE OIL DI KAPAL MT. DS ROSA.

Abstract

This research provides an in-depth examination of the critical impact of Seawater Pump failure on the efficiency of Palm Oil cargo tank cleaning for the fulfillment of cargo quality standards on the MT. DS ROSA, a Chemical/Oil Tanker operating a cargo transition from Palm Oil to Aniline Oil. The malfunction of the Seawater Pump, which serves as the primary supplier of washing water pressure, significantly failed the pressure's effectiveness in overcoming the high viscosity of Palm Oil residues that tend to solidify on tank walls. Consequently, tank cleaning efficiency drops drastically, leading to repetitive cleaning processes (re-cleaning) that not only extend operational duration (time loss) but also result in Wall-Wash Test failures an absolute requirement for Aniline Oil cargo. This quality failure directly triggers financial risks in the form of delay penalties (demurrage) and increased operational costs. The research method employed is descriptive qualitative with a focus on Case Cause Analysis through a comprehensive Case Study. Data were collected through direct interviews on board, ship operational documentation (Logbooks and Maintenance Records), as well as an in-depth analysis of pump failure records and historical Wall-Wash Test reports. This case study analysis identifies the causal factors of failure and the complex relationships responsible for cleaning inefficiency and cargo quality failure. The results of this study structurally demonstrate that Seawater Pump failure has a significant impact on the decline of tank cleaning efficiency, affecting not only the ship’s operational readiness but also financial stability due to demurrage risks. To address this issue and maintain operational sustainability, this study recommends solutions focused on optimizing Seawater Pump performance through adjustments to Preventive Maintenance procedures based on troubleshooting findings. This research also highlights the importance of awareness regarding the interdependence between technical system reliability (pumps) and the fulfillment of the highest cargo quality standards.
