Abstract

The turbocharger is a critical component in a ship's main engine system, enhancing combustion efficiency and engine performance by accelerating airflow into the cylinder combustion chamber. One of its key components is the turbine blade, which converts exhaust gas energy into mechanical energy to drive the compressor.This study aims to analyze damage to the turbine blade caused by exhaust valve rupture, where broken valve fragments enter the turbine side, negatively affecting turbocharger performance. The research employs a descriptive analysis method using fishbone analysis, with data collected from observations, logbooks, journals, manuals, documentation, and interviews.The findings indicate that the primary cause of turbine blade damage is foreign object ingestion (FOI), specifically fragments from a fractured exhaust valve in the main engine’s cylinder head. This fracture led to blade failure, significantly reducing the turbocharger’s efficiency. To maintain optimal main engine performance, strict adherence to the onboard manual book is strongly recommended.

Abstract

The Fresh Water Generator (FWG) is a device on ships that converts seawater into freshwater through the processes of evaporation and condensation. FWG is essential for various purposes such as consumption, washing, and engine cooling. This study aims to address three main research questions: what maintenance methods are applied to the FWG evaporator plate, how does the FWG perform before and after maintenance, and how effective is the system after the maintenance is conducted.The research was carried out on the MV CNC Jawa by analyzing the effectiveness of maintenance on the FWG Type AQUA-125-HW evaporator plate through direct observation, interviews with ship crew, and analysis of logbook data. The evaluation used a fishbone diagram to identify the factors contributing to decreased maintenance effectiveness, including human resources, maintenance methods, materials, and machinery.The results show that both preventive and corrective maintenance—such as routine cleaning and the use of Ameroyal chemical agents—successfully improved heat transfer efficiency. Freshwater production increased from 5–8 tons/day to 13 tons/day, energy consumption decreased, and FWG operation became more stable. The evaluation concludes that proper maintenance strategies and crew training are essential in ensuring the reliability of the FWG and the overall operational efficiency of the vessel.

Abstract

Sistem pelumasan memiliki peran vital dalam mendukung kinerja permesinan di kapal, termasuk diesel generator yang berfungsi sebagai pembangkit listrik utama. Penelitian ini bertujuan untuk menganalisis penyebab menurunnya tekanan minyak lumas pada diesel generator Hyundai H32/40 di kapal MV.CMA CGM VERDI. Metode penelitian yang digunakan adalah kualitatif dengan pendekatan diagram fishbone. Data dikumpulkan melalui observasi, wawancara, dan dokumentasi selama pelaksanaan praktek laut.. Hasil penelitian menunjukkan bahwa penyebab utama penurunan tekanan minyak lumas adalah kelalaian operator dalam perawatan mesin, kerusakan komponen pompa dan filter LO yang kotor, tidak optimalnya pelaksanaan sistem perawatan terjadwal (PMS), serta kualitas minyak lumas yang buruk. Akibatnya, sistem pelumasan tidak berfungsi secara optimal, mengakibatkan gesekan antar komponen mesin meningkat, keausan prematur, dan overheating yang dapat berujung pada kerusakan mesin secara menyeluruh. Untuk mengatasi masalah ini, diperlukan penerapan PMS yang ketat, termasuk pemeriksaan rutin filter dan pompa minyak lumas, analisis berkala terhadap kualitas minyak lumas, serta pemantauan visual kondisi mesin untuk deteksi dini tanda-tanda masalah. Penelitian ini memberikan kontribusi signifikan dalam meningkatkan pemahaman dan pengelolaan sistem pelumasan diesel generator di kapal, yang pada akhirnya dapat meningkatkan efisiensi operasional dan mengurangi risiko kerusakan mesin.

Abstract

Sea transportation is essential to global logistics, and the efficiency of a vessel’s propulsion system is critical to operational performance, especially on LPG carriers. Turbochargers enhance diesel engine volumetric efficiency by utilizing exhaust gases to compress intake air, enabling more complete combustion and greater power output. Declining turbocharger performance can reduce engine power, increase fuel consumption, and raise exhaust gas temperatures beyond safe limits. This study investigates the impact of turbocharger performance on the main engine power output of the LPG/C Cipta Diamond vessel. This study employs a descriptive qualitative approach, using data collection techniques such as direct observation, structured interviews with chief engineers and technicians, and documentation of engine logbook data. The collected data were analyzed using the Fishbone method (Ishikawa diagram) to identify the root causes of the observed decline in turbocharger performance. The findings indicate that several factors influence turbocharger performance, including the physical condition of its components, the cleanliness of the air intake ducts, exhaust gas temperature levels, and lubricant quality. Additionally, human factors and maintenance scheduling were found to significantly affect the stability of turbocharger performance. Mitigation measures implemented to address performance degradation include routine maintenance, examination of exhaust gas pressure and temperature, replacement of wear-prone components such as bearings and seals, and the use of air pressure and temperature monitoring systems to enable early detection of performance decline.

Abstract

The crankshaft is a vital component of an engine that converts the linear motion of the piston into rotational motion to produce mechanical power for electricity generation. This study employs a descriptive qualitative method, utilizing data collection techniques such as observation, interviews, and literature review. The objective of this research is to analyze the factors contributing to the occurrence of cracks in the crankshaft of a diesel engine used as a generator prime mover. The findings indicate that the cracks are primarily caused by contamination of the lubricating oil with water, resulting from leakage in the lubricating oil cooler or tube oil cooler. Another contributing factor is the loosening of the connecting rod bolts, which may occur if they are not tightened to the specified torque or if a torque wrench is not used during installation. Corrective measures undertaken include replacing the gasket, repairing or replacing the leaking tube oil cooler, and retightening the connecting rod bolts using a torque wrench in accordance with the manufacturer’s specifications.

Abstract

Boilers experience frequent problems, such as scale formation, unstable steam pressure, incomplete combustion, and difficulty starting. Therefore, this study uses a quantitative method with the Failure Mode and Effect Analysis (FMEA) approach, which aims to determine maintenance and prevention to minimize these problems. This method determines the failure priority obtained from the Risk Priority Number (RPN) calculation based on assessment factors such as severity, frequency of occurrence, and the likelihood of failure being detected in each component. The results of these calculations indicate that the steam drum component falls into the highest category, with an RPN of 32. The other 12 components fall into the medium category: the feed water pump, electrode, photocell, nozzle, blower fan, solenoid valve, fuel pump, blowdown valve, main steam valve, scum valve, non-return valve, and gauge glass, with RPN values ranging from 12 to 24. Furthermore, the components in lowest category include the fuel filter, safety valve, and manometer, with RPN values ranging from 8 to 10. Therefore, the recommended improvements based on the FMEA results can be used as evaluation material to ensure the effectiveness of the improvements. Furthermore, regular boiler maintenance and monitoring are required, especially for components such as the steam drum, which requires additional routine maintenance schedules, repeated evaluations related to water treatment, and determining appropriate repairs for any steam drum failures.
