The operation of ship tankers is very complex, where officers and crew (ABK)
are required to be able to properly complete the loading and unloading and loading
of cargo tanks according to tank cleaning instructions (tank cleaning guide) to
facilitate ship operations. In carrying out the activities of tank cleaning on board
the ship cannot be separated from the support of tools, ship crew, as well as the
condition of the vessel being operated. The success and failure of tank cleaning can
determine the progress of a shipping company in operating a tanker fleet. The
method used in this study is a qualitative method through the fishbone diagram data
analysis method and the fault tree analysis method. Analysis of the factors causing
the problem shows 3 main factors causing the problem. The source of this research
data comes from observing the implementation of tank cleaning on board during
the period January 2016 to February 2017.
The results showed that the factors which caused the tank to be less than
optimal were the implementation of cleaning tanks that were not in accordance with
the procedures, lack of understanding of tank cleaning, faulty maintenance of
equipment and butterworth spray which was not optimal. The efforts made to
overcome the tanks that were not sprayed with butterworth were to always carry
out the officer checking when the tank cleaning took place, holding a tank cleaning
exercise with different types of load, always taking care of the equipment used for
tank cleaning.
From some of the conclusions above, there are still some shortcomings in the
process of carrying out the tank cleaning correctly, so the authors provide advice
always carry out safety work meetings before carrying out the tank cleaning
process and perform job evaluations after carrying out tank cleaning. If the tank
cleaning process is underway and equipment damage is unavoidable, the crew must
dare to enter the cargo tank and spray the tank walls.
