Abstract

The equipment used for transporter materials is an important part of a shipyard. This is a necessity of the shipyard, especiallythe medium-sized shipyard, which serves to move materials from the warehouse to the field at the production process stage.This manual ship bottom replating activity requires quite a lot of time and workers in the process, so the results obtained areless efficient and uneconomical. In the process of repairing a ship to replating a plate, an obstacle was found, namely therepair of material in the position of the plate at the bottom was very difficult. Basically, the transfer of a material is carriedout by a crane with a certain capacity and conventional methods of using pipes as a means of moving it. Looking at thedevelopment of technology in modern times, it can all be said that technology is already robot-based. Therefore, the design ofa transporter material tool was carried out that could support the work of replating the plates at the bottom of the ship. Theresults obtained from the evaluation of the suitability of the equipment and the application of an information system in the useof transporter materials are information about the list of lifting equipment needed based on the weight of the construction andthe parts to be replating, especially at the bottom. From this modeling, quite efficient results were obtained with softwaresimulations with standard results of 1: 3 from data in the field. It is hoped that the manufacture of the tool model can facilitatethe work of replating the plates on the bottom of the ship.

Abstract

Dependence on materials for the small ship industry can cause other problems. The development of cheap, environmentally friendly, and sustainable small ship manufacturing raw materials is a challenge that must be faced, this gave rise to the idea of developing asphalt-matrixed bamboo (Gigantochloa apus) composite materials with added latex (Hevea brasiliensis) as small ship hull skin material. The asphalt-latex composite material reinforced with apus bamboo fibers was tested using a three-point bending test and a Charpy-type impact test concerning ASTM. The test results showed that the asphalt-latex composite material reinforced with bamboo fibers had an impact toughness of 57.2 kJ/m² and a flexural strength of 6.4 MPa.

Abstract

The joining of steel in ship construction was carried out through welding technology. One of the joining processes used two types of welded joints, namely butt and lap joints. This study identified the strength of the test material from ASTM A36 steel plates at welded joints by standardizing the tensile test. Experimental activities using a tensile testing machine and simulation activities using SolidWorks. The average tensile test values for butt and lap joints show yield strengths of 288.89 and 200 N/mm2, final strengths of 419.11 and 280 N/mm2, reduction of cross-sectional areas of 49.33 and 43.33%, strain 7% and 18.67%, modulus of elasticity 60.81 and 15 N/mm2. Tensile test simulations for butt and lap joints showed plastic deformation in the weld face, root, toe, and HAZ area. Experimental and simulated difference values for butt joints range from 941.67 to 1,519.67 N/m2, and lap joints range from 1,030 to 4,694 N/m2. The final results show that SMAW welding with the butt joint type has a higher strength value than the lap joint.

Abstract

Ship Movement is an important factor in shipbuilding. In determining the ship's maneuverability, there are many aspects that must be considered in the design, namely resistance and angle of attack of the waves. In determining the angle of attack of the waves, the test uses the trigonometry principle to determine the angle of attack of the waves. Where the results of the 3 maneuvers of the Heave, Roll and Pitch ships at speeds of 0 knots, 0.389 knots, 0.778 knots, 1.166 knots, 1943 knots, it is known that the displacement model ship can be used in an open area with a set scale.

Abstract

Ship's Ferries are a sea crossing that continues to operate around the time. The consequence related to shipping activities is an increase in ship exhaust emissions. One alternative for ship propulsion that is environmentally friendly is the Flettner rotor. The working principle of the tool follows the theory of the Magnus effect, where the force arises due to the difference in pressure between the two sides of the Flettner rotor. This study implicates the Flettner rotor on the Kalianget-Kangean ferry route with variations in wind speeds of 10, 15 and 20 knots and variations in dimensions of 3x1, 5x1 and 7x1 meters with a rotational speed of 500 rpm. Optimal results through computational fluid dynamics (CFD) simulations show a coefficient of lift (CL) of 3.647 and a lift force (Fl) of 2,980,631.2 kilonewton with dimensions of 5x1 meters and a wind speed of 15 knots. While the implicit percentage of Flettner rotors in KMP. DBS I of 18.11%, KMP. DBS III of 11.27%, and KMP. NS 92 of 5.45%.

Abstract

Indonesia is a maritime country where most of its territory is in the form of oceans, so many people utilize its marine resources. The sea is currently widely used as a transportation medium for people and logistics using commercial ships. With so many commercial ships in Indonesia, the ship repair industry is also increasingly needed because it requires regular maintenance and repair according to the rules of ship classification. Hull repair treatment includes scraping, washing with fresh water, blasting (full blasting, sweep blasting, and spot blasting), painting, and replating (based on ultrasonic thickness test results). This research will focus more on container ships, bulk carriers, and oil tankers. In ship repair, the condition of the ship’s body, especially the hull, is the most critical concern. The calculation of the volume of hull work on each shipyard is different, making it difficult for the ship owner to estimate the repair time to be carried out. In this case, this study aims to determine the efficiency of the volume of hull repair work on commercial ships so that maintenance/repair work can run optimally. The method used is the calculation of Lloyd’s Registers with the Analytical Hierarchy Process (AHP). The analysis results show that the ship’s hull work is significantly different on the MT. Cosmic 15 because it has a difference in calculations from the shipyard with Lloyd’s, which is 203.636 m2. In the Analytical Hierarchy Process (AHP) analysis, the calculation of CR (Consistency Ratio) gets inconsistent results because the value is more than 0.1, namely 5.303. This is because of the data on the hull area of MT. Cosmic 15 is different in each shipyard where the ship docks.

Abstract

Salah satu hal penting dalam sebuah kapal adalah hambatan. Semakin rendah nilai hambatan pada kapal maka semakin baik kapal berlayar dengan effisien. Untuk mengurangi hambatan kapal beberapa penelitian sebelumnya menggunakan konsep centerbulb. Pada penelitian ini bertujuan untuk mengetahui pengaruh penambahan centerbulb bentuk Foil terhadap besarnya hambatan kapal katamaran tipe NPL 4a. Penelitian ini fokus pada pengaruh besarnya rasio dimensi centerbulb terhadap lambung kapal katamaran tipe NPL 4a yang menggunakan metode penelitian yaitu memodelkan 1 model lambung katamaran NPL 4a dengan S/L 0,2 dan Kapal katamaran yang di uji memiliki demi-hull yang simetris dengan beberapa variasi kecepatan yaitu Fr = 0,19 – 0,37. Bentuk centerbulb yang dipakai ialah Foil NACA 0030 dengan memodelkan 3 variasi besar rasio bentuk terhadap lambung kapal yaitu 10% - 30% dengan peletakkan pada 1/3 Lpp. Hasil penelitian dari keempat model kapal, model 1 tetap memiliki nilai hambatan yang rendah pada kecepatan Fr 0,19 – 0,37 daripada ketiga model lainnya (model 2-model 4). Namun model 2 memiliki potensi yang lebih baik dalam menurunkan hambatan daripada model 3 – model 4 apabila menambahkan variasi posisi centerbulb seperti pada penelitian sebelumnya.

Abstract

Landing Platform Dock (LPD) ships as amphibious warships with complex accommodation systems, including lavatory installations, require effective and efficient installation methods. This study was motivated by the need to compare two lavatory installation methods, namely the conventional method and the modular method, in an effort to increase productivity and reduce the amount of rework in the construction of LPD ships. The research method used is the direct observation method at the national shipyard, with data collection through installation time records, number of man hours, material costs, and number of rework events. Data were analyzed using a quantitative descriptive approach by comparing these variables in each type of lavatory. In this study, 3 types of lavatory with different dimensions and shapes were used. The modular method which requires 10-14 days to complete has proven to be significantly more efficient in terms of implementation time compared to the conventional method with results of 19-25 days according to the type of lavatory. Likewise in the number of man-hours needed, which reached 384-480 JO for the conventional method and 264-456 JO for the modular method in the three types of work. The costs incurred for this production require IDR 67,880,890 - IDR 81,377,090 for the modular method and IDR 71,682,490 - IDR 87,713,090 for the conventional method. Thus, the modular method has proven to be more effective in increasing productivity and reducing the cost of installing a better lavatory.
