In the oil and gas industry, the purification and handling of oil and petroleum gas, the cycle of warmth transformation is expected to isolate the H2S and CO2 from natural gas with an amine. The cycle happens inside the amine reboiler which is a shell and tube heat exchanger type. Cycle liquid streaming in the Amine Reboiler are Lean Amine on the shell side (HEXSS) and Therminol-55 on the cylinder/tube side (HEXTS). With such synthetic arrangement, worked with high weight and temperature, makes the liquid into a destructive climate for Amine Reboiler. Along these lines, an exact review and planning program is needed to guarantee equipement’s life, guaranteeing the protected establishment and wellbeing of laborers. Thus, it is important to direct a danger assessment for shell and tube heat exchanger gear utilizing the Risk-Based Inspection technique which alludes to the API RP 581. The danger of Amine Reboiler is a mix of the Probability of Failure (PoF) and the Consequence of Failure (CoF). From the PoF and CoF acquired, the HEXSS hazard level on the danger lattice at the RBI date and RBI plan date are ordered as Low Risk and Medium Risk. While the danger level of HEXTS on danger network at RBI date and RBI plan date both are ordered as Medium-High Risk. At that point the prescribed date to do the assessment is January 1, 2020.

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.

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.

Indonesia is known as the biggest archipelagic nation on the planet and is between two significant seas. In a roundabout way, Indonesia has tremendous regional water when contrasted and the land territory itself. With this, obviously, it tends to be said that Indonesia has colossal potential in the oceanic area, particularly since the Indonesian sea domain has consistently been a worldwide transportation path. This potential should be used ideally by this country, considering the mechanical advancement in Indonesia itself can be supposed to be very quick. Innovation that is utilized carefully and applied to the sea world can give Indonesia benefits for a few areas, for example, the economy, industry, and even schooling. Innovation that can be used in the oceanic world, particularly in the field of transportation is PC illustrations innovation, which in its application can be utilized during the time spent to plan, fix and support, reproductions and preparing for training and others with the 3D display. Virtual Reality (VR) is a counterfeit world or can be said as a computerized world where everything in there is the consequence of representation made utilizing 3D innovation from the PC. Virtual Reality permits us to cooperate and encounter encounters that are practically like this present reality. The reason for this exploration or the last task is to use innovation that is growing quickly well in the learning cycle in the oceanic world. With Virtual Reality, it is conceivable to make new learning strategies for training, particularly in the presentation of segments of the fuel oil framework on the ship. Because of a few restrictions confronted when mentioning direct objective facts to the ship, including authorization or admittance to enter the ship, time is restricted. Along these lines, it is normal that utilizing Virtual Reality can help the learning cycle for training by making an application that can be utilized in perceiving and understanding the segments of the fuel oil framework on a ship.

Cavitation is a detrimental phenomenon to ship operations because it causes many losses. It caused some effects i.e decreased propeller efficiency, damaged propeller material, lower ship speed, vibration, and extreme noises. In that regard, this research conducts cavitation analysis on controllable pitch propeller (CPP) by varying number of blade i.e. 3, 4 and 5 blades; diameter i.e. 30, 40 cm and 50 cm; also pitch i.e 0.4, 0.6 and 0.8.Â The research method is carried out by the author in this study by conducting a simulation method based on the CFD approach. The simulation process consists of 3 stage-post processor, solver manager, and post-processor. From the simulation based on the CFD approach result, it was found that propeller rotation has an effect on the pressure ratio value. As the propeller rotation increase, the value of the pressure ratio will increase as well. The value of the pressure ratio in propeller design affects the cavitation area that occurs in the propeller. The percentage of the cavitation area on the propeller has an increasing tendency with the number of blades, rotation, and pitch. On the propeller with diameter 300 mm, 3 blades, pitch 0.8 at rotation 125 rpm no indication of cavitation, then it increases to 1.41% at rotation 175 rpm and keeps getting higher at rotation 225 to be 4.22% from total propeller expanding area. Whereas at rotation 225 rpm and pitch 0.4 is 3.38 %, then it becomes 3.85 % at pitch 0.6, which is getting bigger at pitch 0.8 that is 4.22 %.

The purpose of this study is to establish the importance of parameters in a water absorption process for natural particulate composite for ship’s hull applications. To attain useful and reliable outcomes, the subjective evaluation of the assessor and weights of inputs are combined in a PROMETHEE and analytical hierarchy process (AHP) approach. The PROMETHEE serves the goal of ranking while the AHP is deployed to establish the objective weighing. It was found that time is the heading parameter for the natural particulate thermoset composite solutions, compared with thickness and length. By integrating PROMETHEE and AHP, it was proved that this approach offers a higher level of confidence to composite developers than initiative practices that currently dominate choices of parameters. It is particularly useful for natural particulate water absorption parametric selection since it is an innovative and scientific choice approach involving multicriteria analysis.

Container port’s loading-unloading process is still using heavy equipment with less eco-friendly fuel. However, currently, several container ports are implementing an eco-friendly port (green port) concept. Renewable natural resources, such as the sun’s heat energy, are used as an alternative to supports the green port concept. Container cranes, the main heavy equipment in the loading and unloading processes, are generally supplied with electricity from PLN and diesel generators. In this research, it was tried by modeling container crane’s one-line diagram into ETAP, but by adding renewable energy resources simulation, such as solar panels. Solar panel’s characteristics, such as voltage and output frequency are different from PLN and diesel generators. Then, the difference results will be analyzed. After the simulation, results in comparison, known that solar panels can be used for container crane’s electrical system supply. In this study, the PV’s inverter output voltage is 0.38 kilo-volt. The PV supply simulation results in lower power efficiency and higher voltage drop than the PLN and diesel generator’s supply. As for each PV supply scenario, power efficiency and drop voltages are still within the IEC and IEEE standard limits. For example, in the gantry scenario, the power efficiency is 94.44%, and the drop voltage is 0.274%.
