The Hull Strength of Marine Current Turbine Platform Baidowi, Achmad; Arief, Irfan Syarif; lintang, lintang candra
International Journal of Marine Engineering Innovation and Research Vol 2, No 3 (2018)
Publisher : Institut Teknologi Sepuluh Nopember

Strength analysis of hull structure of marine renewable energy is crucial. The hull structure must be able to whitstand the harsh environmental load such as wave, wind and the weight of the payload and the structure itself. This paper analyzies the structural hull strength of marine current turbine platform. The platform is held by 4 mooring lines in 200 m water depth. The hull material is AISI1050 with yield stress 530MPa, the analysis consist of stress analysis which consider the dynamic motion of the platform due to wave, current, win and mooring line tension. The dynamic motion shows the maximum gravity acceleration is 1.3496G. The gravity acceleration creates additional loads due to weight multiplication of payload and structure. From the dynamic analysis using numerical software, the maximum mooring line tension due to dynamic analysis is 300.74 kN and this tension will creates stress in the moring line connection structure in the platform hull. The maximum stress of the is 126.045Pa, The mooring line tension is the highest loads compared to other factors such as weight. The safety factor of the structure based on the analysis is 4.2 which can be calculated by comparing the yield stress of the hull material and the maximum stress occurred due to dynamic load

The Use of Taguchi Method in Design of Dies Propeller Production Using CNC Machine Jadmiko, Edi; Wahyunugroho, Purwadi

Publisher : Institut Teknologi Sepuluh Nopember

Propeller is a rounded blade that rotates in a circle, helping to move a vehicle by pushing against water or air. A speed boat's propeller moves it forward by spinning against the water. Propellers use the laws of physics to propel, or drive forward, an aircraft or a boat. The basic structure of a propeller is a spinning or rotating the shaft with wide, curved blades attached to it. The very simplest propellers were first used in ancient Greece, where the inventor Archimedes invented a "screw propeller" that moved water for irrigating crops. A method for making propeller is to use a casting method with sand mold. In operating the sand mold can only be used for one use, and in the molding process must be reconstructed which of course requires cost and additional time so it is less efficient. Therefore, making a propeller with a permanent mold is the right solution. In this study, the design of dies propeller production process with CNC (Computerized Numerical Control) machine was designed using the MasterCam software simulation method. In addition, variations in machining parameters feed rate, retract rate and depth of cut were also carried out using the Taguchi method. From the research has known the step of dies propeller production process and the time for cutting that used to calculate the most efficient variable variation. Based on the simulation that has been done, for making dies propellerÂ requires ten steps of processing, there are facing, pocket, contour (top die), surface rough pocket, surface finish contour (top die), surface finish parallel, contour (bottom die), and surface finish contour (bottom die). From a series of work processes designed, the total processing time was produced for top die 729,17 minutes and cutting power was 9,734 kWh and for bottom die is about 1329,65 minutes and cutting power was 14,543 kWh.

Analysis of Lift and Drag of Mono-foil Hysucat due to Longitudinal Foil-placement Variation Suastika, Ketut; Dikantoro, Regi Y.; Purwanto, Dedi B.; Setyawan, Dony; Putra, Wing H. A.

Publisher : Institut Teknologi Sepuluh Nopember

CFD simulations were conducted to study the effects of a hydrofoil and its relative placement in the longitudinal direction on the total resistance of a mono-foil hysucat (hydrofoil supported catamaran). Three foil positions were considered: (i) precisely below the vesselâ€™s center of gravity, (ii) 3 chord-lengths aft from position 1 and (iii) 6 chord-lengths aft from position 1. At relatively low speed (volumetric Froude number FnV < 1.8), the hydrofoil results in an increase of the total resistance of the hysucat (up to 4.43%). At relatively high speed (FnV > 1.8), the hydrofoil results in a decrease of the total resistance (up to 34.86%). The resistance coefficient first increases, takes a maximum value and then decreases with increasing Froude number. The maximum value is observed at FnV â‰ˆ 1.4 (or Fn â‰ˆ 0.5), consistent with previous observations. The most optimum foil placement is that precisely below the center of gravity of the vessel.

The gas central processing plant as a facility used to process natural gas had a variety of components that were so complex and many in number. To reduce the risk of failure of these components it was necessary to carry out maintenance. But it would be very inefficient if all the components were treated at the same level, considering that there were so many and the human resources that were owned were very limited. Therefore, in taking care of these components it was necessary to prioritize them according to their critical level. In this research, in determining the critical level of a component using risk-based methods according to the available standards, namely NORSOK Z-008. By making a hierarchy and asset level register of all components, then the value of the probability rating and consequence rating was determined. So that the criticality ranking of each component was obtained according to the criticality risk matrix that was converted from the company's risk matrix, so that the critical level of the component was obtained in the levels of H (high), M (medium), and L (low). With the critical level of this component, the company did not need to take care of all the components. In this research, there was 33 equipment with 140 subunits/subsystems, and the total number of components was 674. Of the 674 components as many as 28 components had a critical level of H (high), 192 components had a critical level M (medium), and 454 components had L critical level (low) of each critical level that has been obtained, it is not necessary to carry out maintenance with the same level to all components. In this research, every component that has H (high) criticality level will be treated as a Preventive Maintenance, while a component with a critical level of M (medium) will be Preventive Maintenance if needed, and a component with L critical level (low) will be treated Corrective Maintenance.

MV Minajaya Tuna Long Liner Ship number 11 is a fishing vessel and one from 24 Minajaya shipsets owned by PT. Industri Kapal Indonesia (IKI). Minajaya 11 has 512 GT capacity hence, it is prohibited by the government to be operated. Therefore Minajaya 11 will be converted into fish carrier vessel, fish carrier vessel scenario itself is sailing to several fishing grounds locate at WPP 716 in Indonesia and to objectify Minajaya 11 as fish carrier vessel, ship production cost has to be analyzed. The Calculation of ship production cost generally divided into three different types, those are reparation, installation and dismantling, from three different groups there are divided into 4 different task, human resources, material, equipment and energy cost. The total cost from reparation is Rp. 850.000.000 with the biggest proportion came from human resources with 49% proportion and the lowest proportion came from energy price with 2% proportion. The total cost from installation is Rp. 1.545.000.000 with the biggest proportion came from material and shipping cost with 88% proportion and the lowest proportion came from energy cost with 0% proportion. The total cost from dismantling is Rp. 25.700.000 with the biggest proportion came from human resources cost with 77 % proportion and the lowest proportion came from material cost with 0% proportion. Total conversion production cost needed by Minajaya 11 is Rp. 2.902.000.000 while the conversion activities will be finished in 5 months and 6 days approximately.
