Abstract

Ships are often used to move cargo, and their main engines are crucial. Accidents and financial losses might result from the main engine being in poor condition. Before completing maintenance, conducting a failure analysis is necessary. The existing method is static and involves using a list of failure modes from the engine's manufacturing phase. This study proposes a preliminary design of dynamic system prototype that seeks to improve ship engine monitoring of status. It includes features such as a list of failure modes and codes based on ISO 14224:2016, data collection unit worksheet, and dynamic charts for visualizing the results. Two testing iterations were performed on the prototype. First, literature data obtained from the internet was used to generate annual and monthly report charts, confirming the functionality of the prototype. Second, real data from engine failures on the tanker ship were used to ensure logical correlations among failure causative factors. The result from real data testing included Structural Deficiency (STD), External Leakage Fuel (ELF), and Breakdown (BRD) were shown. Based on these results through the prototype simulation, can be taken into consideration for the ship's crew and shipping company management to plan oil monitoring, heating the oil properly, and conduct routine maintenance check as a preventive action to reduce the impact of engine damage in the future due to Engine Breakdown and Structural Defiency.

Abstract

In the work breakdown structure for shipbuilding of machinery outfitting is related to machinery, ducting, hvac & piping, steel work, and insulation. Integrated work breakdown structure is one of the shipbuilding methods involving in management, so that design time is shorter. The ducting, HVAC & piping is the system based on the contract assignment and drawing approval by classification society. Then, we compare the effect of each Time Estimation. Then, continue with combine product and project structure. Problem start with how do we compare old with new WBS technology, no optimization process, and no working breakdown structure for the outfitting in the engine room. Bar chart, combination of industrial and financial system with design software also program project evaluation and review technique methodology will be used. Results obtained a work breakdown structure for Guidelines. The Aim was for optimization process time. The schedule created compared with the actual schedule that occurs so that we can see there is a difference of time shows that the shipyard applies integration. This also will lead to man-hour optimization. It is concluded that an integrated work breakdown structure can be applied to obtain the shipyard design in a shorter time.

Abstract

A sea-going vessel will always face the risk of rough weather along with its voyages. The focus of this paper is on the creation of a data-based model to estimate the power increase or speed loss due to the influence of weather, by using resistance estimation theories and added resistance approximation methods along with additional assisting tools. Furthermore, a theoretical simulation is done in order to benchmark and correct the model setup. The analysis of simulation results shows that at the available data range, the model proves reasonably precise within its capabilities, for academic applications. The general behavior of the model complies with common ship theory, however, does not perfectly resemble the speed-power relation of the ship’s recorded data averages. The analysis suggests that the model is most compatible with the shipload draft of 9,0 to 9,5 meters and within the speed of 19 to 22 knots. The lack of data outside the typical operating range disables the ability to verify the model correspondingly. The theoretical simulation proves valuable in assessing ship data-based models.

Abstract

Marine business is one of the largest businesses in the world. Exports and Imports of human necessities in the majority are using ships. This is because of the ratio between the goods that can be delivered on each trip and the number of trips it can go to fulfill this. This makes the shipping or transport cost-efficient. But the continuous growth of the world population and its standard of living creates an ever-increasing dependency for the world economy on international trade. Therefore a good shipping company will always develop a better way of shipping together with more efficient and optimized voyage planning. To increase the efficiency of shipping, companies try to reduce the cost of almost everything. Therefore, one of the options for improving the efficiency of shipping is by increasing the efficiency of the ship itself. The ship efficiency is not only determined by how fast the ship and how much the ship can load, but also how much fuel does the ship consume for each operation. An investigation of the engine efficiency must be done. The investigation will be done by using an engine model in Simulink to create a similar engine model to the real engine. Then simulate the dynamic process of the engine, which will affect the consumption in general. Therefore the consumption of the engine can be analyzed. The results of this bachelor thesis is an explanation of how to develop the engine model. This includes the explanation of what is the engine efficiency and the engine parameters that affect efficiency, such as engine consumption, engine losses, etc. The model development includes the change in parameters and model structure. Then a simulation is done to compare the results with the measured data. From this process, the model can be considered satisfactory when the results are similar to the measured data.

Abstract

A water brake loads the diesel engine will set desired work points and work curves. So that can find a safe point and control safety. After this, the essential system component will be created the model in block diagram and the block diagram will be simulated with Simulink. This requires a model of combustion machine and its control as well as break system and its control. The valve angle also affects the amount of flow or discharge of water which resides in the brake system. The amount of water flow in the brake system affects the amount of load that will be accepted by the main engine. The model is to be validated with measured data. To define load characteristics for a parallel operating visualization, these load characteristics are to be simulated. The results of the modeling were to know PI controller parameters to control the main engine. In the investigation, then simplify the process of modeling results are displayed in the form of a curve. Where in the curve we can see the performance of the engine and brake system so that the operation of the main engine will get maximum condition within safe limits.

Abstract

Crude oil contains mixed of hydrocarbons, the most commonly found molecules are alkanes (paraffins), cycloalkanes (naphthenes), aromatic hydrocarbons, or more complicated chemicals. In the process of taking crude oil in subsea pipeline system with depth 1200 meters, the contents of crude oil like sulfur, paraffin, asphalt could deposit in the wall of the pipe because of the different temperature between crude oil and wall of the pipe. The deposition can make blockage to the pipe and cause crude oil flow to be slow or stop. In this bachelor thesis, will be design double walled pipe for Subsea pipeline system with depth 1200 meters and simulation double walled pipe to knowing the impact of double walled pipe to crude oil flow in Subsea with depth 1200 meters. Based on the simulation that has been done, using double walled pipe could stabilize the temperature between crude oil and wall of the pipe. It shows that the average of temperature decrease using double walled pipe is only 0.125 K for 12 meters. So, it could get the conclusion based on the simulation of double walled pipe that the impact to crude oil flow is there’s no blockage in the pipe and the crude oil flow will steady.

Abstract

The thermal oil system is one type of heater that widely used on ships. The system is an important system used to heat fuel that will be used for the operation of the main engine, auxiliary engine, and boiler. This system has been installed on 17500 LTDW Product Oil Tanker, MT. Parigi, but not yet tested so that it does not know whether the system is able or not to transfer heat from heating equipment (boiler and economizer) to each fuel tank in accordance with the desired value. Therefore, this research performs an engineering evaluation in term of heat transfer analysis to ensure that the heat transfer process of thermal oil from heating equipment to the fuel tanks is already meeting the required temperature or not. This analysis is done by using thermodynamic equation, namely heat balance equation and heat loss equation. The result shows that the heat transfer of thermal oil to each fuel tank corresponds to the desired value, namely 180oC for the thermal oil inlet temperature to each fuel tank and 140oC for the thermal oil re-enter temperature to the heating equipment.

Abstract

Many shipping companies were trying to deliver their cargoes as quickly and reliably as possible. But in the beginning of the latest economic crisis on 2007, the containership fleet is slowing down. Even though world oil prices are now declining, but based on the prediction of World Bank, the price of oil will rise again in 2017. Even some shipping company implements slow steaming method on the operation of their ships. But they do not know whether these methods are effective or not due to any negative effects arising from an implement of slow steaming like increased sailing time so may result in losses to the shippers. This study aims to give suggestions on which ship speed is most optimal for shipping companies by considering technical and operational, financial and also environmental aspect then will be selected one by using Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method. While for criteria and sub criteria weighting are calculated by Analytic Hierarchy Process (AHP) method using Expert Choice software. From the TOPSIS method, super slow steaming was chosen to be the first rank.
