Abstract

Fresh Water Generator (FWG) sangat penting untuk mengubah air laut menjadi air tawar di kapal, menopang operasional dan kehidupan kru. Selama pelayaran MV. Sao Oasis, penurunan produksi FWG diamati, berpotensi mengganggu ourutaperasi kapal. Penelitian ini mengidentifikasi penyebab penurunan ini dan mencari solusi perbaikan. Menggunakan metode deskriptif dan studi kasus berdasarkan observasi dan dokumentasi teknis, penelitian menemukan bahwa faktor-faktor utama yang mengurangi produksi air tawar adalah: penumpukan scaling (kerak garam) di evaporator dan penukar panas, penurunan suhu di penukar panas shell and tube, penurunan tekanan vakum di evaporator, dan penurunan suhu air laut yang masuk ke sistem. Keempat faktor ini mengganggu proses penguapan dan kondensasi FWG. Untuk mengoptimalkan produksi FWG, langkah-langkah yang diambil meliputi: perawatan evaporator rutin dengan sirkulasi kimia, pembersihan kondensor berkala untuk mencegah penumpukan kerak, dan pemantauan kinerja harian melalui pencatatan logbook. Evaluasi data logbook membantu mendeteksi penurunan kinerja lebih awal dan merencanakan perawatan preventif, memastikan FWG beroperasi efisien dan stabil.

HL Dalrymple Bay ditemukan indikasi penurunan kinerja kompresor, khususnya saat manuver, ditandai dengan lamanya waktu pengisian dan tekanan udara yang tidak mencapai standar. Permasalahan ini berisiko mengganggu operasional kapal secara keseluruhan. Penelitian ini difokuskan pada faktor yang menyebabkan turunnya kinerja kompresor pada proses pengisian botol angin, dan apa dampak dari penurunan kinerja tersebut terhadap efisiensi dan keselamatan operasional kapal. Penelitian ini menggunakan pendekatan kualitatif deskriptif. Pengumpulan data dilakukan melalui observasi langsung selama praktik laut selama 12 bulan, serta dokumentasi teknis lapangan. Data dianalisis untuk mengidentifikasi gejala, akar permasalahan, serta solusi teknis yang relevan. Ditemukan bahwa penyebab utama turunnya performa kompresor adalah sistem pelumasan yang tidak optimal, kebocoran pada cylinder head, serta keausan pada piston dan ring piston. Dampaknya adalah waktu pengisian botol angin menjadi lebih lama dari standar, serta munculnya potensi gangguan pada manuver kapal. Rekomendasi meliputi pelaksanaan perawatan berkala, penggantian komponen aus, serta peningkatan keterampilan kru melalui pelatihan teknis.   Filling the air bottle on the ship is a vital process to support the main and auxiliary engine air starting system. However, on the MV. HL Dalrymple Bay was found to indicate a decrease in compressor performance, particularly during maneuvering, characterized by long charging times and air pressure that did not reach the standard. This problem risks disrupting the overall operation of the ship. This study focuses on the factors that cause the decline in compressor performance in the process of filling air bottles, and what is the impact of this decrease in performance on the efficiency and operational safety of the ship. This study uses a descriptive qualitative approach. Data collection was carried out through direct observation during marine practice for 12 months, as well as technical field documentation. The data is analyzed to identify symptoms, root causes, and relevant technical solutions. It was found that the main causes of the decline in compressor performance were suboptimal lubrication systems, leaks in the cylinder head, and wear on the pistons and piston rings. The impact is that the time to fill the air bottle becomes longer than standard, as well as the appearance of potential interference with the ship's maneuvers. Recommendations include the implementation of periodic maintenance, replacement of worn components, and improvement of crew skills through technical training

Abstract

Penelitian ini bertujuan untuk menganalisis faktor penyebab dan dampak dari tersumbatnya nozzle burner pada auxiliary steam boiler di kapal MV. Pan Kristine. Permasalahan yang muncul berupa penurunan tekanan uap dan flame failure saat kapal berlabuh, yang diduga disebabkan oleh gangguan pada sistem pembakaran. Data dikumpulkan melalui observasi langsung, wawancara dengan kru mesin, dokumentasi, serta studi pustaka. Hasil penelitian menunjukkan bahwa penyumbatan nozzle burner disebabkan oleh kurangnya perawatan rutin sesuai Planned Maintenance System (PMS), sistem filtrasi bahan bakar yang tidak efisien, nozzle yang aus atau rusak, serta jarak elektroda yang tidak sesuai dengan manual book. Dampak dari kondisi ini meliputi penurunan efisiensi pembakaran, peningkatan akumulasi jelaga dan kerak di ruang bakar, serta gangguan operasi boiler secara keseluruhan. Penelitian ini merekomendasikan penerapan PMS yang ketat, pemeriksaan berkala pada filter dan nozzle, serta pelatihan kru untuk meningkatkan pemahaman terhadap sistem pembakaran guna menjamin keandalan dan efisiensi kerja auxiliary boiler.   This study aims to analyze the causes and impacts of nozzle burner clogging in the auxiliary steam boiler aboard the MV. Pan Kristine. The issue arose from steam pressure drops and repeated flame failures while the ship was anchored, suspected to result from malfunction in the combustion system. Data were collected through direct observation, interviews with engine crew, documentation, and literature study. The findings reveal that the clogging of the nozzle burner is caused by insufficient routine maintenance according to the Planned Maintenance System (PMS), inefficient fuel filtration, worn or damaged nozzles, and electrode spacing that does not comply with the instruction manual. These issues lead to reduced combustion efficiency, increased soot and scale accumulation in the combustion chamber, and overall operational disruption of the boiler. The study recommends implementing a strict PMS, regular inspection of fuel filters and nozzles, and improved crew training to ensure the reliability and efficiency of the auxiliary boiler system.

Abstract

The performance of a diesel engine is greatly influenced by fuel. Diesel engines really need clean fuel so that engine combustion is maximized. Many companies today prefer fuel oil because it is cheaper than other fuels but fuel oil is still contained by water, mud and dirt so it requires a purifier aircraft to separate the fuel from these impurities. The purpose of this study is to find out how the results of diesel engine combustion are if maintenance is carried out on the purifier periodically. This research method uses descriptive qualitative. The data source was obtained directly by means of observation and documentation as well as literature related to this research which was carried out during the sea project for 12 months at KM.

Abstract

Air motor starter is a component that functions to rotate the engine auxiliary flywheel to move the piston for the first combustion to occur. In this system, high-pressure air from a compressor or air tank is used to drive a starter motor that is directly connected to the engine crankshaft. As the starter motor operates, pressurized air is channeled into the starter motor cylinders, creating a rotational movement on the shaft that eventually rotates the auxiliary engine crankshaft. Air motor starters on MT Green Stars are essential for the auxiliary engine starting system on board MT Green Stars. This study aims to analyze the factors that cause the failure of auxiliary engine start failure caused by the rupture of the starter motor water bearing and the impact on the auxiliary engine. This research uses a descriptive analysis method using HAZOP data analysis techniques and data collection from observations, logbooks, journals, manual books, and interviews The research was conducted on the MT Green Stars ship which has three auxiliary engines and is experiencing problems with the starting system. Based on the research, failure factors in auxiliary engines are caused by several factors, namely starter motor water, injectors, starter motor water, and fuel filters. The impact of auxiliary engine start failure causes failure of the electrical system, system, pump, hydraulic and pneumatic system disorders, work efficiency disorders, risk of damage to the main engine, and safety and regulatory disorders. To handle it, maintenance needs to be carried out, both preventive maintenance and breakdown maintenance. The suggestions that researchers make are to routinely carry out maintenance according to PMS (Planned Maintenance System), carry out toolbox meetings, check especially auxiliary engines
