International Journal of Marine Engineering Innovation and Research Vol 2, No 4 (2018)
Publisher : Institut Teknologi Sepuluh Nopember

In the process of distributing LPG to all regions in Indonesia, LPG stations have an important role. In operation, LPG stations may have hazards caused by environmental conditions such as pipe fatigue (fatigue) due to geotechnical forces or failure of components in the system. Research case of piping systems used pipe stress analysis. The purpose of this analysis is to know the deflection of the pipe, the loads that occur by the pipe, and the safety of the pipe and its support. This analysis refers to the code or standard ASME B31.3 where the stress analysis is performed using software. In the process of pipe modeling, there are variations of loading such as pressure load variation, wall thickness and elevation of soil degradation value. From the results of calculation and simulation pipe stress analysis using software can be seen that header pipe 12 inch at LPG station of Semarang is NOT stress, so it is safe to be use. The thickness of the pipe allowed for to be unstable when the operating pressure is greater than 0.15 inch, and the operating pressure allowed for the pipe to be unstable at a thickness of 0.4 pipe (schedule 40) is less than 725 Psi (50 Bars).

Global Warming is the most compelling environmental issues in the world recently. Almost a century, the temperature increased 0,74° Celsius and made the ice in North and South Pole melt in high rate.Some people say that global warming brings the negative effect for the society, however businessman, especially in shipping and logistic industries, believe that the melting ice process will shorten the distance between East Asia Countries and European Countries. Melting ice in Arctic Sea, open a new route, called Northeast Passage. Using Northeast Passage will reduce distance and time of the voyage.The big idea of this thesis is to compare 2 routes between Northeast Passage and Suez Canal for delivering cargoes from East Asia countries to European Countries or vice versa. Comparing total resistance, total fuel consumption and total cost for bunkering and additional charges are the main topic on this bachelor thesis.Results of this research, total fuel consumption for conventional route is 5810,231215 tons with operational hours of a vessel is 596,15 hours and the total fuel consumption per hour is 9,74625 tons/hour. By using Northeast Passage, a vessel can reduce 1900 nautical miles or saves 17% from the normal distance. There are 2 methods for calculating the resistance of the ship when passing through ice condition, Lindqvist and Riska method. If a vessel wants to save 20% of their fuel consumption (Lindqvist method: 4621,58 tons; Riska Method: 4670,82 tons) compared to conventional route, a vessel just only save 5% of their operational hour (needs 565,367 hours to travel Northeast Passage). Then, if a vessel wants to speed up and save 11% (528,03 hours) of the operational hour it reduces the saving of fuel consumption to 9% (Lindqvist Method 5270,615 tons; Riska Method 5322,38 tons).Bunkering Plan at conventional route is occurred at Hongkong Port, Port Klang and Piraeus Port with price 463 USD, 460 USD and 467 USD respectively. Suez Canal is controlled by a country so a vessel needs to pay some money for passing through the canal. The total price that needed to be paid for conventional route is 2.997.496,754 USD. Northeast Passage is considered as International water because there is too much complexity about the declaration. So, there is no taxes for a vessel when passing through the passage. Bunkering is occurred at Hamburg and one of Port in Russsian Coastline with price 447 USD at Hamburg and 400 USD at Russian. 1962466 USD needs to be paid for a vessel passing through Northeast Passage from Hamburg to Hongkong. The usage of Northeast Passage can saves 35% of expense or equivalent to 1035031 USD.

This thesis is focusing on how to reduce the NOx emission since it has been an issue in all over the world. An idea that reduced the combustion temperature by integrating an external chamber connected with the combustion chamber as a temporary energy storage. This method is implementing the pressure-temperature law, where the pressure is reduced by expanding the volume that resulted a temperature decreased. The aims of this study were to make a feasibility study of the previous invention, a combustion model simulation and technical drawings design of the external chamber. The simulation model involves an analysis of how the temporary energy stored effected the combustion temperature and calculating the pipeline losses. The results showed that by installing the external chamber, the combustion temperature was reduced significantly by 6.15% for the burn zone and 17.8% for the unburn zone. Furthermore, a comparison of the pipeline heat loss showed that an insulated pipe saved 94.1% more heat energy than the uninsulated. The important factor in designing the external chamber were the spring deflection and piston bore. An analysis shown that the larger the deflection and piston bore, the bigger the pressure drop would be which is why an optimization of those factors were needed.

The world crisis of fossil fuel availability encourages the development to explore alternative energy which is possible to replace of fossil fuel use. The use of biodiesel by using plant oil and animal fats is strived to the maximum extent possible, in order to maintain its sustainability. Cotton seed oil (Ceiba Pentandra) is one alternative that can be used as a replacement fuel. There are four advantages of using Cotton seed oil as a substitute fuel which are: produce a low level of pollutant, guaranteed availability, can be used for diesel engines with little or no modification and in certain mixes can incrase engine lubrication that should incrase engine life. The research was conducted through performance test of YANMAR TF85-MH diesel engine using Cotton seed oil biodiesel with mixture of B30, B20 which has be compared with using YANMAR TF85-MH diesel engine. From the results of performance test, it showed that the using of Cotton seed oil give better effect to performance than fossil diesel fuel use on the same engine. The addition of biodiesel Cotton seed percentage into the fuel provide greater maximum power but it provide the higher fuel consumption value

Propeller is similar to rotating fan blade with having primary function as propulsion system. In order to increase propeller performance, Engineer is developing Energy Saving Devices ( ESD ) to reduces operational cost, clean energy and for long term utilization. The global emmision from marine is 2.7 % in 2007. One of ESD is Propeller Boss Cap Fins ( PBCF ). The focus of this thesis is to design and developed PBCF B - series propeller. This thesis studies the performance of a propeller without and with PBCF such as efficiency, thrust, torsion and dynamic hub vortex phenomenon. To obtain the results this thesis uses Computational Fluid Dynamic (CFD). The PBCF simulations were based on its pitch angle. The simulation results shows that PBCF is achieved the highest efficiency which is 0.60 %, and increases thrust 3.21 %, and torsion increase 2.64 % compared to propeller without PBCF. It also shows that the PBCF is able to break the vortex flow and it will reduces the porosity to the rudder and decrese the corrosion potention to the rudder.

Analysis of Erosion Rate on Discharge Slurry HDPE Pipe in Canal Water Intake PLTGU Grati using CFD Simulation Agoes Santoso; Bahrul Ilmi
International Journal of Marine Engineering Innovation and Research Vol 2, No 4 (2018)
Publisher : Institut Teknologi Sepuluh Nopember

The dredging of the canal water intake at PLTGU Grati is an effort to maintain the depth of the reduced canal due to sedimentation. The dredging process itself uses a cutter suction dredger. To distribute mud or slurry (a mixture of water and sand) result of dredging to dumping area of PLTGU Grati using HDPE (high-density polyethylene), as pipe material, hence pipe does not wear due to corrosion but erosion. Basically, erosion is caused by impact of solid particle (sand) which is suspended inflow (multiphase) on a solid wall boundary. Wear caused by erosion itself is recognized as one of the problems in some industries that distribute slurry in their process. This research thesis analyzes and predicts the rate of erosion occurring in HDPE pipes that are transported slurry from the sedimentation dredging in PLTGU Grati using CFD (computational fluid dynamic) method. Variations of slurry concentration, impact angle, particle diameter and velocity of the slurry has been be performed to determine the effect on the rate of erosion. The results of this research thesis showed that the concentration of slurry, impact angel, diameter of particle and the concentration of the slurry were directly proportional to the rate of erosion on the HDPE pipe.
