Abstract:
Pratomo Angga Putra, NRP. 364210964, “Optimization of Tank Cleaning from FAME
to Methanol Cargo to Achieve a Satisfactory Wall Wash Test on MT. Hanyu Glory”
This study was conducted to evaluate the implementation of cargo tank cleaning
procedures on the oil tanker MT. Hanyu Glory, as well as to assess the extent to which
the procedures align with operational standards established in the maritime industry,
particularly in relation to occupationalsafety, operational efficiency, and compliance with
international regulations such as ISGOTT (International Safety Guide for Oil Tankers and
Terminals) and MARPOL (Marine Pollution). Tank cleaning is a crucial stage in tanker
operations, especially during cargo changeovers or prior to inspections by relevant
authorities.
This research employs a descriptive qualitative method with a field study approach.
Data were collected through direct observation of the tank cleaning process by crew
members, on-site activity observation, and review of documentation related to the
Standard Operating Procedures (SOP) used on the MT. Hanyu Glory. The results indicate
that the tank cleaning process, including pre-cleaning, butterworthing, rinsing, drying,
and gas freeing, was carried out in a systematic manner. However, several obstacles were
identified during its implementation, such as limited cleaning tools, suboptimal technical
conditions of equipment, and a lack of regular training for the crew on updated
procedures.
Based on the analysis, it is concluded that although the tank cleaning procedures have
generally been carried out in accordance with existing basic standards, there is still room
for improvement in terms of effectiveness and safety. These improvements can be
achieved through equipment upgrades, enhancement of crew training systems, and
regular monitoring and evaluation of SOP implementation on board. This study is
expected to serve as a reference for shipping companies in improving the quality of
operational management on oil tankers and in promoting more consistent implementation
of international standards within Indonesia’s maritime industry.
