Abstract

An oily water separator is an auxiliary engine on board that is used to prevent the mixing of oil and water with density differences. The oily water separator is very important on board for the separation of the ship's bilges from oil content which can pollute the marine ecosystem. This matter also fulfills the requirements of MARPOL 73/78 Annex 1 when the researcher carried out a sea project on SS. Golden Isaia, The researcher found the abnormality of the oily water separator. There was a decrease in its discharge volume, in which the normal flow was 5 m 3 / hour, which became 1 m 3 / hour. The purpose of this research was to determine the causal factor of oily water separator decreasing discharge volume on SS. Golden Isaia, evaluate the impacts, and the efforts to solve this oily water separator decreasing discharge volume on SS. Golden Isaiah. This research uses a descriptive qualitative method by applying a fishbone diagram analysis model. Data collection techniques include observation, interviews, and literature review. The interviews involved three informants, there chief engineer the one responsible for all machinery on board, the second engineer whose responsible for the oily water separator, and oiler 1 as the second engineer's assistant. The research results conclude that the causal factors of oily water separator decreasing discharge volume such as the lack of pressure of the oily water separator feed pump, dirty process filter due to accumulated dirt, and unavailability of oily water separator maintenance history. The efforts to solve this oily water separator decrease discharge volume on SS. Golden Isaia such as the change of a feed pump set with the new one, cleaning the strainer and replacing the filter bag, and the documentation of repair and maintenance.

Abstract

This study examines a crucial problem that occurred on board the MT. Nectar, namely air contamination in the lubricating oil of the Cargo Oil Pump Turbine COPT, which is a critical system in supporting the download and unloading process of crude oil. This contamination resulted in a significant decrease in pump performance, increasing the risk of malfunction that impacts equipment safety and the operational efficiency of the ship. This problem not only has a technical impact, but also requires proper maintenance management handling. Using a qualitative approach through direct observation, interviews with crew members, and documentation studies of the maintenance and operation history of the lubrication system, this study analyzed the root cause using the SHEL (Software, Hardware, Environment, Liveware) model and Fishbone Diagram. The analysis results indicate that the main causes of contamination are leaks in the labyrinth seal, inadequate condenser vacuum, and wear on metal bearings due to suboptimal lubrication. To address this problem, the study recommends improving compliance with Plan Maintenance System PMS procedures, implementing routine and periodic inspections of the entire lubrication system, using high-quality components, and improving technical training for crew members to strengthen their understanding of the lubrication system. In addition, a digital monitoring system is needed for early detection of contaminants in the oil. These steps aim to maintain the darkness and efficiency of the COPT system to ensure optimal ship operations. This research is expected to be a useful reference for ship crews, shipping companies, and cadets at the Semarang Maritime Polytechnic PIP in understanding the importance of lubrication systems and preventing contamination in auxiliary machinery on ships.
