Development of Power Management System for Electric Power Generation in Tanker Ship Based on Simulation Indra Ranu Kusuma; Raynaldi Pratama
International Journal of Marine Engineering Innovation and Research Vol 1, No 3 (2017)
Publisher : Institut Teknologi Sepuluh Nopember

Power management system (PMS) for electric power generation in ship, in the case of tanker ship, is the system that has function to control and to monitor all generators in ship as the main electricity supplier for all electric equipments or installed load. The number of total load that supplied by generator depends on the frequency of the use of load itself which would be read in PMS as well. It leads the operator to take a decision on how many generator should be operate whether in parralel or stand alone operation to fulfilling the power needs. Those loads should be grouped into essential and non essential load. This groups affecting the performance of the generators, where it will covers the maximum load at 306.67 kw under the condition of all electric equipments are operated well while the cargo handling of tanker ship is on process. However, in the state of emergency while the non essential electrical equipments are being cut off trough PMS, the generator will only covers the the maximum load at 253.88 kw to fulfilling the same needs. In the extreme case (total efficiency of parralel operation at 70%), the generators would cover the total load at 306.6 kw still by sparing the generated power of 52.72 kw.

Decreasing in fossil energy reserves about 3% every year and has not been matched by the discovery of new energy reserves. Therefore, it is necessary to increase the use of renewable Energy to meet energy needs. Renewable energy is energy derived from sustainable natural processes. Indonesia located in the tropical area, it has a lot of potential ocean energy. OTEC (Ocean Thermal Energy Conversion) is one of many renewable energy sources from the ocean. OTEC or Ocean Thermal Energy Conversion is one of the latest technologies that used the temperature difference between deep and shallow seawater. OTEC system generally used ammonia (NH3) as working fluid. Ammonia is used because it has a relatively low boiling point compared to water. OTEC system consists of evaporators, turbines, generators, condensers, and pumps. In this research, the authors focused on the design of lab-scale OTEC turbines. 2 stage turbine will be varied the tilt which is 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 degree. The computational fluid dynamics (CFD) method is used in this research to simulate the OTEC Turbine. Based on the simulation results, the highest efficiency and net power is a 2 stage 40 degree turbine with 57.45% of efficiency and 287.25 kW of generated power

Subsea tie back systems are important parts of oil and gas production project. The decision to select a subsea tie-back configuration with the objective goal of lowest lifecycle cost can be configured in multiple ways based on the field specifications and operator’s approach to operation. This paper presents an Analytic Hierarchy Process (AHP) method to determine economical levels of subsea tie-back wells configuration, based on lifecycle cost of subsea deepwater production systems with respect to wells number alternative. Field reservoir located in deepwater of eastern Indonesian with the depth of 1400 meters and field life 40 years is studied. From this study, it is identified that the most economical configuration in subsea production systems: satellite tie-back configuration to develop small field with 6 numbers of wells; for 12 numbers of wells, template subsea tie-back configuration is the best.

International Journal of Marine Engineering Innovation and Research Vol 4, No 1 (2019)
Publisher : Institut Teknologi Sepuluh Nopember

Indonesia is no longer known as an oil exporter country but Indonesia has a large deposit of natural gas. This situation will bring the conversion from using fuel oil to gas. It will also support IMO Regulation such as MARPOL 73/78 Annex VI Tier III which was stringent in the regulation to bring the world to achieve near zero emission level. One of the methods to comply with IMO tier III is using gas as a fuel. Therefore, the ship efficiency can be overcome by two aspects simultaneously, cheaper and cleaner gas as marine engine fuel. In this paper, LNG as fuel will be applied to 100 TEUs Container Carrier which is consider several technical aspects when the existing ship is modified so that natural gas can be used safely and well. Things to consider in this LNG re-design are; the volume of tank, bunkering station system, and the Gas Valve Unit (GVU). In addition, this design will also analyze the costs required to modify the vessel so that it can use dual fuel (MDO and LNG) as well as cost comparison when using single fuel (MDO).

Publisher : Institut Teknologi Sepuluh Nopember

The study analyzes about the cause of the leak in KM Nusantara Akbar’s engine room. However, this research is focus on leakage caused by shaft deflectio From the field data provided by the KNKT, know the cause of the leak is packing driven by a shaft deflection and therefore can not hold the rate of water. Analysis was done by a review of the technical and non-technical factors, because the scene of the ship accident was not purely due to technical factors but also non-technical factors. The first step is analyzing the ship document, such as the certificate of ship from classification, incident reports, docking report, ship crew certificates and other ship document. Then on the next step, the evidence that has been obtained from the analysis of the documents related to the ship sail is use to make the analysis using 5 whys method to looking for the root cause. According to the analysis that has been done, the technical cause of the leak vessel caused by system shafting system is reconditioned flange bolts that have been damaged and the addition of flax on the bearing shaft has to cope without straightening axle deflection itself. While the Autodesk Inventor 3D modeling software obtained bolt broken because the act force is 10782.31 N with the shear stress 2.230 MPa, while the maximum force in the normal load is 9.434,531.N with shear force 1,951 Mpa. Then from the cause from non-technical factors are equipment / spare part to overcome the failure of shafting system is very less, the workplace is dirty and uncomfortable and happened miss communication between the crew in the engine room to overcome the leakage.

International Journal of Marine Engineering Innovation and Research Vol 1, No 1 (2016)
Publisher : Institut Teknologi Sepuluh Nopember

This study discusses about safety on board especially during fire condition. During fire, all passengers and crew had to beevacuated into safe place. The study observe at 1200 GT passenger ships, a typical ship which have small dimension vessel characteristic but able to carry passenger more than four hundred persons and also could containt cargo. When the ship was on fire at any circumstances that requires passengers need to be evacuated, itâ€™s obvious that there will be a buildup of passengers when passing through stairs and corridors. The calculation use to estimate evacuation time required based on the IMO guidelines. Studies continued by creating evacuation simulation using Agent-Based Modeling, a simulation modeling that assume human being as an agent that has characteristics resemble to real state of motion. The comparation between the two methods, calculation and simulation are both using two scenarios, day and night conditions. Result show that the simulation generates evacuation time shorter than the calculation method. In the numerical calculation takes 689 seconds and 1595 seconds in day and night conditions, while in the simulation process takes 548 seconds and 1374 seconds in day and night conditions sequentially. This studies also followed by fire modeling study that aims to determine the spread of heat and smoke produced from fire. On the condition of fire, smokewords. production will interfere passengers in the evacuation process. The evacuation time becomes longer and estimates the potential victims affected by fire.
