Oil-loaded tankers are very risky with the occurrence of the problem
of losses. Cargo depreciation may occur in the process of loading, unloading and
hauling activities. The main objective in a tanker cruise is to deliver an oil load (to
the port of destination with the smallest possible shrinkage. To achieve this, it can
be accurately reflected on the factors that cause the shrinkage of payloads, how to
minimize shrinkage, and the amount of shrinkage.
The foundation of this theory explains the definition of depreciation,
the charge duty service during the loading and unloading process, measurement
system, measurement, ship counting, land side calculation, agreement of both
parties.
The method used by researchers to solve the problem is qualitative
descriptive method, so that researchers can explain the results of the research
obtained. Data collection through documentation and observation. Researchers
make direct observations on board the MT. Martha Tender during the loading and
unloading process, the researchers also took pictures to support the validity of
research data.
The results showed: the factors that influence the shrinkage of the
physical depreciation such as evaporation, pump leakage, pipe leakage, shrinkage
such as measurement errors, and charge load errors. The way to minimize the
occurrence of shrinkage is by carrying out loading and unloading procedures.
Large shrinkage of naphta MT. Martha Tender dismantled in Balongan exceeds
the tolerance limit set by PT.Pertamina (Persero) is 0.1%.
From the results of the study it can be concluded that the shrinkage of
payload that occurred in MT.Martha Tender caused by several factors that must be
minimized to the limit of tolerance determined by a shipping company.
Keywords: Losses, Unloading, Load.
