Abstract

A maritime transportation based company used corrective maintenance on these two component,impeller and shaft of fresh water pump inside their ship’s water cooling system. While using correctivemaintenance, these two components are getting maintained when its already in worse condition and made thesystem down. Therefore, a reliability analysis is performed using predictive method to predict when will these twocomponent would break down and then scheduled to fix based on MTTF value of component. Then, the systemwould run without getting disrupted because of the unit’s downtime.

Abstract

important constructions is the construction of propeller strut. The propeller strut is a support consistingof an arm and a bearing that is attached between the propeller shaft and the hull on the stern of the ship. In thisstudy, a modification was made to the propeller strut construction with the cross-sectional shape of the terrain insuch a way that it gave the shape of the cross-sectional profile of the National Advisory Committee of Aeronautics(NACA) and formed a solid cylinder. This alternative strut design is modeled and simulated using the CFD tool inthe ANSYS CFX software so that the average velocity, streamline flow, and pressure on the strut are known. Andexpressions with optimization with the particle swarm optimization method. The results of this study found that theNACA profile 16-021 is the best and efficient profile among 2 other profiles.

Abstract

Sistem bahan bakar kapal merupakan salah satu aset penting yang perlu dilakukan penetapan program pemeliharaan guna menunjang kelayakan kapal dalam beroperasi. Pada penelitian ini dilakukan penetapan program pemeliharaan dengan menggunakan Reliability Centered Maintenance II berdasarkan klasifikasi konsekuensi standar Norsok Z-008:2017. Dengan menggunakan metode klasifikasi konsekuensi berdasarkan standar Norsok Z008:2017, didapatkan hasill bahwasannya terdapat beberapa komponen yang memiliki tingkat menengah dan tinggi, sehingga perlu dilakukan proses lanjutan seperti evaluasi suku cadang maupun penyusunan rekomendasi pemeliharaan dengan bantuan RCM II decision worksheet. RCM II diperlukan untuk menyusun strategi pemeliharaan secara preventive maintenance, diantaranya on condition task untuk komponen seperti fo storage tank, scheduled discard task untuk komponen seperti fo transfer pump, scheduled restoration task untuk komponen fo filter. Selanjutnya dilakukan perhitungan biaya untuk mengetahui berapa biaya perawatan yang dibutuhkan tiap komponennya dan dapat ditarik keputusan akhir terkait jenis perawatan yang sebaiknya digunakan.

Abstract

Currently, there is a growing trend of damages occurring to the main engine, with some cases leading to sailing delays or even endangering human safety. The Crew Boat 41 GT is a vessel operating to transport crews or provide offshore support. Therefore, it is crucial to pay attention to the maintenance of its main engine, especially the cooling sub-system, which plays a vital role in maintaining the working temperature of the main engine to prevent overheating. Consequently, a suitable maintenance scheduling strategy is required for the sub-system components of the Crew Boat 41 GT's main engine to ensure the operational efficiency of the main engine is not disrupted. This study aims to predict the reliability using both qualitative (FMEA) and quantitative methods (theoretical and Monte Carlo simulation) to develop a plan for preventive maintenance scheduling, FMEA analysis identified three critical components, there are sea water pump, heat exchanger, and fresh water pump. The results of the quantitative analysis for these three critical components showed that the RLLM = 0.6, with little difference between the two methods. Additionally, error calculations were performed using RMSE, MAPE, and MAE, with results close to 0. Moreover, from the evaluation of corrective and preventive maintenance, it was found that preventive maintenance is more recommended as it can save costs by approximately 16.26% or Rp 7,703,292.56 for a single maintenance of all components.

Abstract

Main Engine is one of the important compartments on the ship which is located in theengine room. Has a function as a propulsion driver and as the main propulsion engine of theship. With such an important position, scheduling maintenance on the Main Engine is veryimportant to do. Because if the main engine is not running, then there will be no operation ofthe propulsion system on the ship and it will definitely be very detrimental to the ship owner.This final project attempts to answer these demands by creating a maintenance schedule forthe main engine fuel system. In addition, the total operating costs which consist of running,maintenance and downtime costs will also be taken into consideration in determining themaintenance time. In this research, scheduling of main engine maintenance is carried out usingreliability centered maintenance which is used to select, develop, and create alternativemaintenance strategies based on operational, economic and safety criteria. Based on thefailure analysis using Failure Mode Effect Analysis, several component failures wereidentified, such as the fuel injection pump (worn drive shaft, worn governor plunger, fuel gearpump lacking lubrication), injector nozzle (damaged nozzle tip, burrel plunger seal, M/Eperformance was not optimal ), gate valve (nut valve difficult to operate, disk valve has a leak,gasket on valve), fuel oil transfer pump (bearing wear, pump impeller corrosion, shaftcorrosion), swing check valve (crusted disk valve, valve gasket), fuel filter (dirty fuel filter),quick closing valve (crusted disk valve, gasket valve).

Abstract

This study aims to enhance the closed cooling system's reliability on the cargo 3650 dwtship by evaluating maintenance schedules. To achieve this, an effective maintenance program isnecessary. The Fault Tree Analysis (FTA) method is used to analyze potential component failures andidentify main causes. A total of 22 components are identified, including Main FW Cooler, AuxiliarySea Water Pump, Turbocharger, and others. All components are assessed to determine critical ones,included in the minimal cut set table, and relationships for a Reliability Block Diagram (RBD).Additionally, distribution types are determined to model time between component failures and predictsystem reliability. Reliability calculations are done for each component, and results measure overallsystem reliability. Turbocharger is the component with the shortest scheduling time, t=1650 hours, areference for maintenance. The final stage involves cost calculations to compare Corrective andPreventive Maintenance. Preventive maintenance analysis improves cost and time efficiency. Thus,implementing a maintenance program based on this research can enhance cooling system reliabilityon the 3650 dwt ship.

Abstract

Damage to the main engine is currently common, some cases result in sailing delays or eventhreaten human safety. Crew boat 41 GT is a ship that operates to transport crew or support offshore. Thus, it is necessary to pay attention to the maintenance of the main engine, especially the cooling sub-system which plays an important role in maintaining the working temperature of the main engine so as not to overheat. Therefore, it is necessary to predict the failure of the 41 GT crew boat main enginecooling sub-system components so that the right time can be determined to carry out maintenance onthese components before damage occurs. In this study, the prediction of reliability value was carriedout using qualitative (FMEA) and quantitative (theoretical and Monte carlo simulation) methods.FMEA analysis resulted in 3 critical components, namely sea water pump, heat exchanger and freshwater pump. The results of quantitative analysis of 3 critical components at RLLM = 0.6 between thetwo methods are not much different and error calculations have been carried out with RMSE, MAPE,and MAE with results close to 0. So, it can be seen that the MCS method can be applied to predictreliability values.
