Abstract

This study aims to identify factors causing decreased performance of the deepwell cargo pump and the maintenance measures taken to prevent delays in the unloading process on the MT Prima Lautan 1. The research method used was qualitative descriptive, with data collected through observation, interviews, and literature review during practical activities at sea. The results showed that the main factors causing delays in the unloading process on the MT Prima Lautan 1 were inadequate performance of the deepwell cargo pump, and suboptimal maintenance. In addition to technical aspects, it was found that the crew's lack of understanding of maintenance procedures also exacerbated the damage. To address this problem, a series of steps can be taken, such as maintenance and lubricating the deepwell cargo pump, which can improve its performance. Consistent implementation of a planned maintenance system in accordance with the manual and company's SMS can improve the efficiency and safety of ship operations. Therefore, this study emphasizes the importance of preventive maintenance and ongoing training for ship crews to reduce the risk of damage and operational delays.

Abstract

Marine generators play a crucial role in supplying electrical power for overall ship operations. This study aims to investigate the factors causing the temperature drop in the Marine Fuel Oil (MFO) system of the generator on MV. Radiant Reb. The temperature decrease (to 98ºC-100ºC) leads to increased fuel viscosity, flow resistance, and a decline in both combustion efficiency and diesel generator performance. By applying a descriptive-qualitative case study approach involving direct observation, interviews, and documentation, this research identified four primary causes. These factors include: reduced heater performance due to scaling and leaks, a suboptimal steam trap causing condensate buildup, damaged thermal insulation (lagging) accelerating heat loss, and wear on the circulation pump disrupting fuel flow. Corrective measures were implemented through routine maintenance and thorough inspections of these vital components. In conclusion, preventive maintenance and early detection are crucial for maintaining the fuel temperature within the ideal range (108ºC-118ºC) to preserve the operational efficiency and reliability of the marine generator.

Abstract

The hatch cover is an important component on bulk carrier vessels that supports cargo protection and loading-unloading operations. Damage to the hatch cover may disrupt operational activities, increase accident risks, and cause delays in coal distribution. This study aims to analyze hatch cover maintenance and identify critical components with the potential for failure. The research used a mixed-method approach through Reliability Centered Maintenance (RCM). Data were collected through observations, documentation, and questionnaires distributed to ship crews. The analysis methods included Functional Block Diagram (FBD), Failure Mode and Effects Analysis (FMEA), Logic Tree Analysis (LTA), and task selection. The results showed that the hydraulic pipe was the most critical component, with the highest Risk Priority Number (RPN) value of 576 due to leakage causing unstable hydraulic pressure. Other components, such as the hydraulic jack, hatch cover wheels, and chain, also showed significant failure risks affecting hatch cover performance. The recommended maintenance actions include periodic inspections, routine maintenance, and replacement of damaged components. Proper implementation of maintenance is expected to improve hatch cover reliability, operational safety, and the efficiency of bulk carrier operations.

Abstract

The lubrication system serves not only to lubricate moving and stationary parts but also plays a role in cooling the engine. This study aims to identify the factors causing a rise in lubricating oil temperature and a drop in pressure within the diesel generator's auxiliary engine. The research was conducted aboard the MV. Great Venture, owned by Wah Kong. A qualitative descriptive method was employed, utilizing interviews with the Third Engineer. The findings indicate that the rise in temperature and drop in lubricating oil pressure were caused by the clogging of the oil pump filter due to sealant debris originating from the L.O. cooler. The solution to this issue is to perform routine maintenance on the generator engine in accordance with the Planned Maintenance System (PMS).
