Designing Passive Harmonic Filter on Dynamic Positioning Vessel's Electrical System Affected using Electrical Thruster Sardono Sarwito; Indra Ranu Kusuma; Yose Gregory Tarigan
International Journal of Marine Engineering Innovation and Research Vol 4, No 2 (2019)
Publisher : Institut Teknologi Sepuluh Nopember

Ship with a dynamic positioning system has the ability to maintain her position dynamically. To be able to maintain the position, generally, ship with a dynamic positioning system have several thrusters located at bow or stern of the ship. Based on the propulsion system, there are 2 types of thruster which are mechanical thruster and electrical thruster. In electrical type, the thruster is driven by an electric motor supplied from the generator. In addition, on dynamic positioning vessel equipped with the electrical thruster, there are also VFD or Variable Frequency Drive to control the speed of motor thruster. The use of VFD components in the system may cause harmonic interference. Harmonic itself can be regarded as distortion in the sinusoidal waves due to the interference of other waves that have integer frequency multiples of their fundamental frequency due to the operation of non-linear thruster motor. Some of the most affected components of this distortion are the communications equipment and the components used for measurement. This research conducted an analysis of harmonic disturbance arising from the operation of 2 units bow thruster on DP Ship by simulating 6 scenarios of generator configuration using simulation software. The results from this research were total harmonic distortion value or VTHD of the system that complies with standards and rules, also the specification of a passive harmonic filter to reduce the VTHD value at the specific harmonic order.

Design and Simulation of Automatic Ballast System on Catamaran Ship Based on Programmable Logic Control Indra Ranu Kusuma
International Journal of Marine Engineering Innovation and Research Vol 1, No 3 (2017)
Publisher : Institut Teknologi Sepuluh Nopember

Characteristics of catamaran ship which has deficiency to ship stability during maneuvering. to that end, this paper concerns about ballast system design in support of the safety and comfort of passengers on the catamaran boat. the discussion is done by creating a mathematical model of each component in the block diagram of the ballast system. then determine the pid value of the system and add the compensator for the system to run stable. further analyzed with the help of matlab software to get transient system response. with the automation system on the ballast system, it is expected that the motion of the ship can work automatically and provide a better response in the stability of the catamaran type ship. the ballast system begins to work against the tilt of the ship at 6.7 seconds at a certain angle, and will continue to work during the vessel maneuvering. judging from the 6.7 second system response time, the convenience of the passengers is not disturbed (the system response is not too fast). one way to reduce the rolling that occurs on the ship is to optimize the performance of the ballast system. performance optimization is done by using programmable logic controller (plc). plc used is omron cpm1a-30cdr-a-v1. the process is done by making the installation plant model of the ballast system as a control medium. followed by creating a control circuit consisting of wiring i / o, limit switch circuits, power supplies and programming languages associated with plcs. the result of the control is expected to regulate fluid flow in the ballast system automatically resulting in a rapid response to the stability of the ship.

Preservation of mangrove, like efforts on preservation of other natural ecosystem, is directly connected to sustainability. Eco-park as one model of mangrove eco-tourism is well accepted worldwide. Mangrove eco-park comprises of accommodations, edutainment centre, galleries, restaurants, etc. If these facilities are not properly planned and sustainability elements are not incorporated they will have negative effects to the preservation effort. The incorporation of sustainability elements in planning is already a standard practice by many district councils in developed countries like US and UK. Developers are to conform to the sustainability checklists failing which their project many not be approved. To be able to accommodate all type of development proposal the checklists are generic. Conformation to sustainability is required overall rather than the project systems and sub-systems. Therefore the checklists can be used for control purposes but with great limitations. System specific sustainability is required. This study identifies the generic model of a typical mangrove eco-park systems, sub and sub-sub systems and proposed their individual primary sustainability elements. A simplified model has been applied to the planning of transport system for Tanjong Pelepas Eco-Park (TPEP), a mangrove preservation effort by a Malaysian Port Authority. Thirty three eco-park sub-sub-systems have been prioritised and their primary sustainability elements identified. Parties responsible for the sustainability elements, either designer or TPEP operator, or both have been identified. The checklist is expandable and could be used to develop TPEP’s standard operating procedures.

ABSTRACTIn the cylinder of conventional compression ignition engine, temperature distribution and stress variation set up in the entire piston due to the inherent nature of combustion. This project will investigate causes and effects of high gas pressure and temperature on marine two-stroke diesel engine piston. Investigation has shown that stress-related piston damages play a dominant role mainly due to mechanical and thermal stress or combination of both. The simulation parameters that will be considered in this report are piston material, combustion temperature and combustion pressure.In the present study, conventional marine two-stroke diesel engine piston will be modelled using Autodesk Inventor software. The working condition of the piston will be simulated based on the selected parameters using finite element analysis method to analyze the magnitude of mechanical stresses acting on the piston.The piston will be re-designed using a material superior to the conventional piston material and will be optimized by reducing the stresses acting on the piston. Two materials will be used in the analysis after which the results will be compared and the best will be proposed. The structure and stress analysis (mechanical, thermal and thermal-mechanical stress) of the design will be modelled using the software mentioned earlier.

International Journal of Marine Engineering Innovation and Research Vol 2, No 1 (2017)
Publisher : Institut Teknologi Sepuluh Nopember

Maintenance on machines is a mandatory asset management activity to maintain asset reliability in order to reduce losses due to failure. 89% of defects have random failure mode, the proper maintenance method is predictive maintenance. Predictive maintenance object in this research is Steam Generator Amurang Unit 1, which is predictive maintenance is done through condition monitoring in the form of vibration analysis. The conducting vibration analysis on Amurang Unit 1 Steam Generator is because vibration analysis is very effective on rotating objects. Vibration analysis is predicting the damage based on the vibration spectrum, where the vibration spectrum is the result of separating time-based vibrations and simplifying them into vibrations based on their frequency domain. The transformation of time-domain-wave into frequency-domain-wave is using the application of FFT, namely AMS Machinery. The measurement of vibration value is done on turbine bearings and steam generator of Unit 1 Amurang using Turbine Supervisory Instrument and CSI 2600 instrument. The result of this research indicates that vibration spectrum from Unit 1 Amurang Power Plant indicating that there is rotating looseness, even though the vibration value does not require the Unit 1 Amurang Power Plant to stop operating (shut down). This rotating looseness, at some point, can produce some indications that similar with the unbalance. In order to avoid more severe vibrations, it is necessary to do inspection on the bearings in the Amurang Unit 1 Power Plant.

Fossil fuels are non-renewable fuels but are still the main fuel choice however, it is now becoming increasingly recognized that the availability of fossil fuels are dwindling which further encourages research on renewable fuels. One of the renewable fuels under development and research is biodiesel. The use of vegetable and animal oil is one of the primary choices to decrease the use of non-renewable fuels. Candlenut oil is one of the alternatives under research and development to produce biodiesel as a replacement for non-renewable fuels. In this research is expected to know the NOx emission level and combustion process of single cylinder diesel engine using candlenut oil biodiesel and compared with diesel fuel High-Speed Diesel (HSD). The results of NOx emission comparison between biodiesel candlenut and HSD showed an increase of 0.76 gr / kWh for biodiesel candlenut and 0.51 gr / kWh for HSD fuel. In the burning process test results showed the knocking value of better candlenut biodiesel than HSD which is 5.69 bar for biodiesel candlenut and 6.19 bar for HSD fuel.

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

Subsea pipeline is a transportation infrastructure of oil and gas as an alternative for ship tanker. The uneven topography surface of the sea floor resulting the pipe undergoes free span. The free span is a condition endured by the pipe where the pipe position has distance or gap with the seabed supported by two pivot. The free span is at risk of experiencing a vibration caused by the presence of dynamic load that is current and the wave. The vibration that occurs is the impact of the presence of the phenomenon of Vortex Induced Vibration (VIV). The Phenomenon Of VIV occur on a cylindrical component caused by ocean currents, causing the occurrence of vibration by the movement of fluid on the pipe so that it raises the vortex at the rear of the direction of oncoming flow. One way to dampen or reduce the impact of VIV is by adding suppresion device. VIV suppression device is a tool that is installed on the pipeline on offshore piping installationcthat serves to dampen or reduce the impact of VIV. One of the simulations used to know the characteristics of a fluid is to use (CFD) Computational Fluid Dynamic. With the addition of suppression device can add the rest of the operating time on a free span of affected VIV, on the condition of free span critical exposed VIV (Vortex Induced Vibration value) has a life time on plain pipe 44.21 years, on pipe with 53.09 years and Fairing on the pipe with the Helical strike 52.95 year.
