Abstract

Aluminium 5052 on ships can be used in LNG tanks, heat exchangers, bulkheads, and superstructures. Its characteristics that can be used in various types of construction in ships cause aluminium 5052 to meet various temperature conditions. The purpose of this research is to find out the strength of the FSW and TIG aluminium 5052 welded joints due to the effect of working temperature. The methods used are impact test and bending test of aluminium 5052 specimens immersed in liquid nitrogen at -1600C and heated in oven at 1660C. The average impact value of raw materials, FSW specimens, and TIG specimens immersed in liquid nitrogen at -1600C are 1.22 J/mm2, 0.2195 J/mm2, and 0.0663 J/mm2, respectively. The average impact value of raw materials, FSW specimens, and TIG specimens heated in an oven at 1660C are 1.3403 J/mm2, 0.1395 J/mm2, and 0.0870 J/mm2, respectively. The average bending stress of raw materials, FSW specimens, and TIG specimens immersed in liquid nitrogen at -1600C are 394.70 MPa, 85.82 MPa, and 299.49 MPa, respectively. The average bending stress of raw materials, FSW specimens, and TIG specimens heated in an oven at 1660C are 400.45 MPa, 148.58 MPa, and 318.55 MPa, respectively. Weld discontinuity observations shows that all raw material specimens do not have open discontinuities exceeding 3 mm, all FSW specimens have open discontinuities exceeding 3 mm, and TIG specimens shows varied results. The conclusion of this study shows that aluminium 5052 is a material that is resistant to temperature changes and is able to maintain its strength at various temperature conditions because aluminium is an FCC (Face Centered Cubic) material.

Abstract

Natuna is one of the regencies in the Riau Archipelago Province, the area of Natuna Regency is 224,684.59 km2 with a land area of 2,000.85 km2 and an ocean area of 222,683.74 km2. According to the Ministry of Maritime Affairs and Fisheries, Natuna occupies the first position for the purpose of exporting fishery products from the SKPT location (Integrated Marine and Fishery Centers in Small Islands and Border Areas), namely marine fisheries resources reaching more than 1 million tons per year. The extent of Natuna waters and the large potential of existing capture fisheries resources cause the Natuna waters to be included in the Fisheries Management Area (WPP 711) which is prone to illegal fishing activities. It has been proven recently that in the waters of North Natuna there are coast guard ships from foreign countries escorting fishing vessels belonging to their countries that are carrying out illegal, unreported, and unregulated fishing activities. The purpose of this research is to design a patrol ship to carry out security missions around the Natuna waters. The method used in this design is the Parent Design Approach method. This method is known in designing ships, namely by taking a comparison ship that has the same characteristics as the ship to be designed. The main dimensions of the ship obtained in this final project are Lwl = 50.2 m, B = 9.32 m, H = 4.45 m, T = 3.5 m, Vs (max) = 25 Knots, Crew = 40 Indonesian navy. Armaments used on this ship are Oto-Melara 76/62SR 76 mm, Oerlikon Millennium 35 mm, RWS Machine Gun, and SS1-V1 Kal hand rifle. 5.56 mm.

Abstract

This article investigated two different arrays of Wavestar wave energy converter (WEC) with two spherical and conical WEC geometry. The boundary element method and radiation/diffraction theory have been used to evaluate the absorbed power of the Wavestar WECs under different wave heights and periods. For validation of numerical analysis, the heave position and velocity for with and without damping coefficient compare with experimental data. Single Wavestar with spherical and conical geometry under different wave periods were investigated and then two linear and circular arrays for both considering geometries compared with each other. The result shows better performance of a circular array than a linear array for all WECs. Absorbed power by the conical geometry is bigger than the spherical geometry. Besides, the maximum power is belonging to the wave period of 6s and 7s for a circular array while in a linear array the maximum power shift to wave periods of 7s and 8s.

Abstract

The Surabaya coast is a strategic area for sustainable development. For example, Teluk Lamong Harbor was built using reclamation. The port can be a solution but also has a coastal ecological impact. Therefore, a study of the coastline and distribution of the TSS was carried out around the Lamong Bay area. Based on the analysis of shoreline changes, the addition in the west (Kali Lamong) with NSM and EPR reached 166 m and 16.6 m/year and in the east, there was an addition (Osowilangon) with NSM and EPR reaching 337 m and 33.7 m/year. Based on TSS analysis by satellite, TSS in 2012 in the east had an average of 28.42 mg/L, increasing in 2017 to 36.39 mg/L, increasing again in 2022 with a value of 38.46 mg/L. While in the west in 2012, the high TSS had an average concentration of 40.95 mg/L, increasing in 2017 to 44.57 mg/L, increasing again in 2022 with a value of 52.68 mg/L. The modeling results show that the average TSS (west) in 2012 is ±20 mg/L, while in 2022 it is ±60 mg/L. In the east port, the average concentration of TSS in 2012 and 2022 did not change significantly (±20 mg/L).

Abstract

The use of fossil diesel fuels still produces carbon dioxide emissions (CO2), sulphur dioxide (SO2), hydrocarbon emissions (HC), nitrogen oxide (NOx), and high total particles and carbon monoxide (CO). Moreover, the need for transportation of motor vehicles will always increase every year. The emission of exhaust gases resulting from the combustion process can essentially be reduced by improving fuel quality, the homogeneity of the fuel mixture, and regulating proper combustion. There are several ways to reduce exhaust emissions from diesel engines by providing precise injection pressures. This is done to get the perfect combustion. In addition, improving fuel quality is a way to reduce emissions of exhaust gases. Another one is by adding methanol to the diesel. The addition of methanol can reduce the emission of exhaust gas produced. The process of mixing the solar and methanol takes the addition of surfactants to obtain good homogeneity. Testing was conducted using simulation software with engine modeling. The result can be seen in the reduction and the addition of standard pressure 200 bar, that the emulsion fuel in SFOC (specific fuel oil consumption) suffered a decrease and increased by 0.2% and 0.3% at pressure 160 bar and pressure 240 bar. The fuel solution on SFOC suffered a decrease and an increase of 0.3% and 0.25% was produced by pressure 160 bar and pressure 240 bar. The highest NOx is produced by 240 bar injection pressures with Dexlite fuel while the lowest NOx is produced by 160 bar injection pressure with emulsion fuel.

Abstract

Recently, marine big data are significantly increased. If the data are effectively analyzed, it can give an advantage, and we can harness the data that is useful for a decision-maker in maritime industries. The Marine Logistics Database (MLDB) was successfully developed in the previous studies. It was developed by integrating big data into a relational database. By utilizing the extracted data from the developed database (DB), the model of ship allocation will be established. In this study, the main purpose is to develop a ship allocation model that matches the results with the existing ship allocation. In this study, the effectiveness of the allocation model was examined by checking the port constraints, ship specification, and allocation process itself. Moreover, some simulations were executed and discussed to develop new ship allocation and analyze the effective ship specification.

Abstract

Generally, the planning of the material arrangement of the aluminum hull plate is always carried out at an early stage to obtain a material formation that has good economic value. One of the strategies used to obtain economic value in shipbuilding is the use of various grades of plate material. The grade of aluminum material that is often used on ships is the 5xxx series. Where this series has many grades that can be used as ship hull material options. The price difference for each grade of aluminum material for ships is a very influential variable on the economic value of shipbuilding. However, before being applied to shipbuilding, it is necessary to test the feasibility of aluminum plate connections with variations in plate grade. The aim is to provide clear information regarding the technical feasibility of selecting material grades. Therefore, in this study, a simulation will be carried out to test the strength of the plate connection with variations in the grade of aluminum material using the experimental method. The plate joint test is carried out using only the Tensile test in the laboratory with reference to the ASTM rules. The grades of aluminum plate materials used are 5052 and 5083. Connection formations are between 5052-5052, 5083-5083, and 5052-5083. From the test results, the largest average yield stress value is 202.34 N/mm2 at the variation 5083-5083, the maximum average ultimate stress value is 261.70 N/mm2 at the variation 5083-5083. For the variation of the 5052-5083 plate connection, it still has a yield stress value that is greater than the basic yield stress of the material, namely 142.97 N/mm2. Where the percentage value of the achievement level of yield strength is 113.6% of the basic yield stress value of the material based on BKI rules. However, in achieving the ultimate stress value, it is still lower than the ultimate basic stress of the BKI rules standard material, which is 193.88 N/mm2. Where the percentage value of the level of ultimate strength achievement is 70.5% of the ultimate basic stress value of the BKI rules standard material.

Abstract

In Indonesia, many fishing vessels are made from generation to generation in a traditional way. As a result, the ships built did not comply with the regulations and permits of the naval architects. The fishing industry is one of the most dangerous because it works on the high seas. Therefore the performance in hydrodynamics and safety should be evaluated on these traditional vessels. The main objective of this research is to evaluate the hydrodynamic performance and safety of fishing vessels. Following standard specifications or criteria, seakeeping performance is evaluated using Maxsurf Ship Design software. Assessment of existing safety equipment uses IMO (International Maritime Organization) regulations and the Torremolinos protocol. As a result, the ship can only operate at a wave height of 0,1-0,5 meters or undersea state 3. Ship safety inspections reveal that they still do not meet the required requirements and do not have the necessary equipment specified by the World Maritime Organization (IMO).
