International Journal of Marine Engineering Innovation and Research Vol 5, No 4 (2020)
Publisher : Institut Teknologi Sepuluh Nopember

Piston is one of the important parts in the combustion process in a diesel engine, it consists of two namely the piston head and connecting rod, where the piston head consists of three parts, namely the piston crown, piston rings, and piston pins. This paper wants to prove which is more effective in modifying the TCC piston crown shape on a four-Stroke one-cylinder diesel engine fueled with B-30 in terms of noise. To measure noise, several experiments were carried out. One way is to use an application that can help make measurement easier is to use the simulation. The Simulation can measure the level of noise by using the tools in an application the same as in reality. The piston area is very influential on the combustion process, with the greater piston area, the resulting explosion is greater which results in and produces a high pressure also it is directly proportional to the noise level. After everything is measured, then we compare it with the engine's performance and give maximum results between the level of noise with engine performance. The result is using a piston case 4 (+1) which has a larger area experiencing the highest noise level using B30 Diesel Fuel or High-Speed Diesel (HSD) Fuel. Under load conditions, with a 50% load, the noise level on piston +1 (Case 4) experiences the highest noise level using B30 Diesel Fuel or High-Speed Diesel (HSD) Fuel.

Specific Gravity Analysis of Onion Peel and Snail Shell Particulates as Composite Fillers in Ship Applications Sunday Ayoola Oke
International Journal of Marine Engineering Innovation and Research Vol 6, No 2 (2021)
Publisher : Institut Teknologi Sepuluh Nopember

There is limited knowledge on the specific gravity of agro-based fillers, particularly particulate onion peels and snail shells despite their potentials as the ship's hull composite materials. This work reports experimental results on specific gravity concerning particulate onion peels and snail shells as fillers in ship's hull composite fabrication. Specific gravity bottles, water, and 15g each of particulate onion peels, snail shells, and their mixtures were used in laboratory conditions. It was found that onion peel particulates (specific gravity of 1.09± 0.41 for 0.063 mm), snail shell particulates (specific gravity of 0.95 ± 0.01 for 0.063 mm), and mixtures of particulate onion peel and snail shell (specific gravity of 1.02 ± 0.08 for 0.150 mm, 10g particulate onion peels + 5g particulate snail shell) yielded the least values, requiring the least fuel expenditure in generating torque for the desired motions during the ship's voyage. Moreover, a policy to use the snail shell recommendation should be formulated as it is the overall best to help in cost reduction by shipping organizations. Previous studies were on tomatoes and potatoes, among others. However, the present study takes a new direction to innovatively consider hardly studied fillers for polymer composites for the first time.

In the processing of oil and gas, a pressure vessel is an important piece of equipment. It needs a method to prevent the failure of the pressure vessel. The Risk-Based Inspection (RBI) is a systematic approach to the inspection management method for equipment based on the level of risk. RBI is expected to provide sufficiently accurate recommendations to prevent equipment failures. In this research, the objects to be carried out are the 10V2102 condensate separator and the 10V2103 condensate storage vessel. According to RBI analysis, the risk category of the current RBI date is low risk for the condensate separator 10V2102 and condensate storage vessel 10V2103. Meanwhile, the inspection date of Condensate Separator 10V2102 is 2 April 2026 and 11 February 2027 for Condensate Storage Vessel 10V2103 and selected inspection methods are Visual Testing, Ultrasonic Testing (UT), Radiography Test (RT), Eddy Current Test, and Magnetic Particle Inspection.

Fuel accounts for the majority of the ship's operating costs. Increased propeller efficiency can help to reduce fuel usage. The higher the efficiency, the less energy is wasted. Ships with high propeller efficiency may be able to provide more thrust while using less fuel. Propeller Boss Cap Fin (PBCF) installation is one of the solutions for improving propeller efficiency that is ideal for a submarine. PBCF may lower the submarine's energy usage, allowing it to recharge its batteries less frequently. According to certain studies, PBCF can boost propeller efficiency by 7% while lowering noise levels by nearly 6 decibels (dB). The impact of PBCF phase lag variation on skewed propeller performance and flow will be the subject of this article. CFD simulation using phase lags of 0, 12.86, 25.72, and 38.58 will be used in the study. The simulation shows that PBCF can improve propeller efficiency while lowering propeller torque. Even though all phase lag modifications show a reduction in propeller thrust. On its hub vortex, they also reveal the existence of distraction.

Noise level onboard, particularly in the engine room, requires a careful monitor to not causing any disruption or discomfort to the shipboard environment. For monitoring purposes, an appropriate alternative system can be applied if the noise level exceeds the limit set by applicable regulations such as IMO, ABS, and LR. The current research uses computational methods to map noise contours in the engine room and recommends some muffler models to reduce the noise level in the MV Natuna Express engine room. Based on the field measurement, the noise level exceeds the Standards value at a maximum of 110 dB. Mapping and designing of the muffler models were based on the measurement data. Simulation results show that greater transmission loss hence noise reduction is affected significantly by the expansion of muffler chamber length and diameter. Modification of the muffler chamber using plywood and the tailpipe on both ME ON Generator ON and ME OFF Generator ON conditions respectively reduce the noise approximately by 24.94 dB and 10.50 dB.

Biodiesel Waste Cooking Oil is Environmentally Friendly Alternative Fuels and More Feasible than Fossil Fuels Hadi Prasutiyon; Aguk Zuhdi MF
International Journal of Marine Engineering Innovation and Research Vol 5, No 3 (2020)
Publisher : Institut Teknologi Sepuluh Nopember

The use of diesel engines is increasing at the moment, the other hand, supplies of petroleum base diesel oil in the market decreasing. Therefore we need alternative fuels to use as supplement fuel for diesel engines. Biodiesel processing can be done with the process of esterification and transesterification. Biodiesel is processed from used cooking oil can be done only by the transesterification process. Ester transesterification is the process of converting into esters in another form by reacting carboxylic esters and alcohols with an alkaline catalyst (NaOH), in processing biodiesel transesterification process is the process of converting triglycerides of cooking oil into methyl or ethyl ester as biodiesel. According to various studies, biodiesel derived from waste cooking oil proved to be more environmentally friendly fuels than the results are known and used today. Nitrogen Monoxide emission levels (NOx) in the biodiesel from used cooking oil to produce emissions 12% lower than emissions produced by diesel oil. Another advantage, the exhaust emissions of the unburned form of carbohydrates produced biodiesel used cooking oil turned out to be 25% lower than on diesel oil. The diesel engine durability test, performance analysis, analysis of the degree of damage is indicated by the metal content in lubricants, and test the properties of each lubricating it can be some conclusions as follows.

The Literature Study on Corrosion Rate in Mooring Chain for Tropical Seawaters – Class Rules Review Hasan Ikhwani; Sista Mutya Atikanta; Wimala Lalitya Dhanistha
International Journal of Marine Engineering Innovation and Research Vol 6, No 1 (2021)
Publisher : Institut Teknologi Sepuluh Nopember

Many design codes for structures in tropical waters are still based on the code for the North Sea, even though both have different environmental conditions. This research was conducted to assess the influence parameters of the tropical water environments and to determine the empirical estimates of the parameters that have a major effect on the corrosion that occurs in tropical waters. The result of this study will produce a practical equation function to estimate the corrosion loss based on the parameters of temperature, current velocity, and dissolve Nitrogen (DIN) for two different levels, low concentration level DIN, and high concentration level DIN. The function can analyze the estimation of corrosion that occurs in two different locations in the chain, the splash zone area, and immersed area. The corrosion rate (mm / year) obtained from the empirical estimation is then validated with the actual measurement data from the field obtained from the available literature. The empirical estimation results show a good fit when compared with data from existing actual measurements. Furthermore, the validated estimation results and actual data are compared with the existing class/code rules wear allowance. The corrosion rate results in particular conditions that exceed the corrosion wear allowances in the rules for data on tropical waters.
