Abstract

Ship Classification Agency is a service business that is different from other industrial fields. By looking at the links and participation in the pace of the maritime industry and the existence of the Ship Classification rules which were made as a reference, the essence of the existence of shipping services from the Classification Board has a strong background to support the advancement of the maritime industry. Clearly, the Ship Classification Bureau must establish and establish standards or benchmarks, guidelines or rules for reference from planning, construction, and periodic surveys of commercial ships and other forms of marine building construction. Class certificate which shows the regulations of the rules will describe the ship concerned as having the construction feasibility and the machines to be used as planned. Thus, a ship classified will provide security for life and the goods transported on the ship, including the prevention of pollution from the surrounding sea which is caused in its operations.

Abstract

Untuk menghindari permasalahan dalam mengoperaikan purifier dibutuhkan suatu standart yang baik,dimana kesalahan dalam pemilihan ukuran grafity disc akan berakibat fatal dalam sistem pemisahan minyak dengan kotoran. Perbandingan antara masukan dan keluaran pada proses purifier haruslah seimbang dengan toleransi yang masih diperbolehkan,sehingga tidak terjadi tumpahan / overflow yang sangat merugikan dengan terbuangnya minyak selama proses pemisahan karena ketidak mampuan gravity disc dalam menjaga minyak hasil proses pembersihan purifier.

Abstract

The propeller plays a crucial role in the maritime industry, particularly in ship propulsion systems. However, it often experiences low performance, commonly due to imbalance. So this research aims to determine the damage and handling of unbalanced propellers and their solutions. An early indication of this problem is unstable rotation, which is generally caused by component damage or imbalance. This research highlights the damage found in the propeller and its shaft. The findings reveal significant erosion, wear, and cracking, particularly on the inner part of the shaft and the propeller blades. These damages result in imbalance, which negatively impacts other components and the overall propulsion performance. To address this issue, technical inspection and clarification by the Indonesian Classification Bureau (BKI) are necessary to ensure safety and restore the optimal function of the ship’s propulsion system.

Abstract

The reliability of the inert gas generator system plays an important role in maintaining operational safety and combustion stability in shipboard systems. However, operational disturbances often occur due to failures in the combustion detection process, particularly in the flame eye detector component that monitors flame intensity during ignition and operation. These disturbances can cause interruptions in the combustion process and reduce the performance of the inert gas generator system. Therefore, this study aims to analyze the utilization of management analysis in identifying and mapping problems occurring in the inert gas generator in order to determine the root causes and appropriate corrective actions. This research employs a descriptive qualitative method to obtain comprehensive data related to the operational performance of the inert gas system. The research process begins with systematic problem mapping followed by field observations to collect real operational data from the inert gas generator system. Data collection is conducted continuously to identify the primary cause of the disturbance. The analysis focuses on several aspects, including the set-point regulation of light intensity readings detected by the flame eye detector, the timer set-point requirements during ignition, and the system’s response to combustion light intensity. The results indicate that failures in the flame eye detector reading process and improper set-point timer configuration significantly influence the interruption of the combustion process in the inert gas generator. Predictive analysis assists in narrowing down the potential causes and identifying the most critical factors affecting system performance. These findings highlight the importance of systematic management analysis in diagnosing operational problems and improving the reliability of inert gas generator systems.
