Abstract:
This study discusses the factors causing contamination of refined petroleum cargo
and the preventive measures applied on board MT. Olyvia. Cargo contamination is a
critical issue in tanker operations as it can reduce cargo quality, lead to cargo rejection
by terminals, and cause operational as well as financial losses. This research was
conducted based on the author’s sea training experience as a deck cadet on board MT.
Olyvia, focusing on the loading and handling of Bio Solar B35 and Pertalite cargoes.
The research employed a qualitative descriptive method with a case study
approach. Primary data were obtained through direct observation of tank cleaning, tank
drying, cargo readiness inspections, and interviews with officers and crew involved in
cargo operations. Secondary data were collected from ship documents, operational
manuals, and relevant literature related to refined oil cargo handling. The results indicate
that the main factors contributing to potential cargo contamination on MT. Olyvia include
suboptimal tank cleaning and drying processes, insufficient thoroughness during final
tank inspections, and limitations in operational coordination and supervision. Preventive
measures include optimizing tank cleaning procedures in accordance with established
standards, strengthening officer supervision, implementing layered inspection systems,
and enhancing crew competence and discipline. Through consistent procedural
implementation and improved operational management, the risk of refined oil cargo
contamination on board MT. Olyvia can be effectively minimized.
