Abstract

The purpose of the present study is to calculate and verify the viscous resistance of a remotely operated inspection submarine which is used for the purpose of underwater inspections.The focus of the study is to investigate the effect of a vertical fin on the total value of the viscous resistance. In the design of a submarine, determination of the viscous resistance plays an important role. The smaller the viscous resistance,  the smaller is the engine power to be required, which results in a more economic vehicle during the operation. Viscous resistance calculationswere done by computational fluid dynamics (CFD) and verifications by wind tunnel experiments. Three models of submarines were simulated and tested. Results of data analysis show that the effect of an installation of a vertical fin on the total viscous resistance is not detectable in the current experimental setting. Furthermore, comparisons between simulation and experimental results show that the root mean square errors (RMSE) are, respectively, 2.48 x 10-3, 3.18 x 10-3 and 2.88 x 10-3 for model I, II and III.

Abstract

Ship structure composed of stiffened plates is subjected to a variety of loading conditions during service, which can lead to buckling. As a result of panel buckling, the overall strength of the ship hull girder is reduced, which is what determines the ultimate strength of the hull girder. The ultimate strength analysis can be accomplished with finite element (FE) simulation, but detailed modeling can be time-consuming. Due to these reasons, it is more advantageous and costeffective to replace the three-dimensional (3D) stiffened panel model with a two-dimensional (2D) equivalent single layer (ESL) plate. This shift from 3D to 2D is premised on the accuracy of ESL in representing the various buckling modes of stiffened panels, which are determined by panel topology and boundary conditions. Therefore, an equivalent single layer plate (ESL) that represents a stiffened panel is evaluated in different buckling modes. Considering that ESL is asymmetric in nature, any modification of the stiffened panel's geometry has a significant effect on the buckling modes. In this paper, we are concerned with two modes of buckling: (i) local buckling within the stiffeners of the plate and web, and (ii) local lateraltorsional buckling within the stiffeners. According to the results, ESL is capable of accurately predicting the effect of local buckling in combination of biaxial compression and lateral pressure.

Abstract

RoPax vessels are widely used worldwide but contribute to numerous fatalities. Accidents result from human factors, vessel damage, management, and natural causes. Vessel stability is a significant concern, with WoD leading to increased load and rising KG, potentially causing capsizing. This study examines a RoPax OCD UFP that experienced a WoD-related accident in Indonesian waters. Modifications considered are standard freeing ports, becoming RoPax OCD SFP, and applying side casings, or RoPax OCD WS assessed the Stockholm Agreement. Fluid simulation and stability failure criteria were employed at varying wave heights. The largest RAO on the variation of heading angle is changed into stability criteria, resulting in realistic outcomes that have not been seen in earlier research. The highest RAO roll occurs at a heading encounter angle of 60 degrees with a value of 2.192362 degrees/m. Results show survival for RoPax UFP, RoPax SFP, and RoPax WS in the 0-1 m wave height range, with only RoPax UFP capsizing at 2-3 m. RoPax WS has an extended stability arm but decreases stability at high wave heights. RoPax SFP is unaffected by WoD but may still face capsizing depending on the pure stability arm GZ factor. Modifying RoPax UFP to RoPax SFP or RoPax WS can improve survival intact stability.

Abstract

BUMDes Mutiara Saghara mengembangkan usaha baru berupa Eduwisata Garam, yaitu wisata edukasi yang memperkenalkan proses pengolahan garam rakyat secara tradisional serta inovasi modernnya. Meskipun sektor garam berpotensi meningkatkan perekonomian warga Desa Bunder, saat ini kontribusinya masih belum optimal. Akibat dari minimnya kontribusi ini, produksi garam oleh petani tidak memberikan keuntungan ekonomis yang signifikan. Untuk mengatasi permasalahan tersebut, program pengabdian kepada masyarakat ini bertujuan mengintegrasikan sistem desalinasi air laut yang menghasilkan garam dan air hasil evaporasi. Pengabdian dilakukan secara bertahap mulai dari mendesain alat, mengadakan bahan baku, membuat alat, melakukan uji alat dan menyerahkan alat kepada mitra. Dalam proses utamanya, air hasil evaporasi yang memanfaatkan panas matahari akan dialirkan melalui pipa saluran ke bak penampung dan kemudian diproses dengan teknologi reverse osmosis (RO) untuk menghasilkan air bersih. Inovasi ini diharapkan dapat meningkatkan kualitas garam dan memberikan manfaat lain yaitu dapat menghasilkan air bersih. Sistem RO dirancang dapat menghasilkan air bersih 1000 gpd.

Abstract

The Musi River is an important transportation route in Indonesia, where traditional boats such as Jukungs and Keteks are widely used. Both are open-deck vessels, making stability a crucial factor for safety and operability. This study analyses and compares the stability of a Jukung and a Ketek in order to provide insights for safer traditional boat design. The methodology involves calculating the stability moment (MGZ) at a given heel angle and the heeling moment (MKR) due to turning and passenger distribution, based on Biro Klasifikasi Indonesia (BKI) and the GM₀ value specified by International Maritime Organization (IMO). Numerical simulations based on hull geometry are also applied for a more detailed assessment. Although similar in size, the Jukung has greater displacement owing to its flat U-shaped hull extending from top to bottom. Reducing passenger loads lowers the centre of gravity and increases the height of the righting lever. Both boats satisfy stability criteria across loading cases; however, the Jukung consistently demonstrates higher MGZ values, which increases further as the load decreases. Findings show that both vessels remain stable with MGZ exceeding MKR. The Jukung maintains a positive GM₀ under all loading conditions, whereas the Ketek fails to meet stability requirements at higher loads but is acceptable at reduced passenger levels. Overall, the Jukung proves more stable and safer, with its hull form providing a larger righting lever and greater safety margin than the Ketek. This highlights the critical role of hull design in ensuring traditional boat safety along the Musi River.

Abstract

Tankers are one of the popular modes of transportation associated with liquid cargo. Efficiency with respect to the volume of cargo transported by tankers is an essential consideration in the transportation business process, especially fuel oil, which has become a benchmark for the global economy recently. Various studies have been carried out to optimize cargo space. This study aims to define the factors that influence cargo compartment efficiency to increase the effectiveness in the transportation business. In this study, it is known that the transverse bulkhead arrangement affects the payload capacity, which is related to the criteria in the naval architect principle. The hopper design also influences the optimization of cargo volume, which can provide benefits in terms of payload. Excess cargo volume on existing ships due to hopper design optimization, the future ship design can reduce the length of the cargo compartments that still meet the desired payload. Reducing the length of the cargo hold will undoubtedly provide an opportunity to optimize the scantling analysis for longitudinal and transverse ship structures. This study is expected to be a reference and a more detailed discussion regarding the efficiency of cargo space on tankers in the future.

Abstract

Jukung fishing boats, prevalent in Prigi, face challenges due to their wide design (approximately 5 meters on both sides). This excessive width often necessitates berthing further from the coast. To address this issue, this study investigates the feasibility of reducing outrigger width to increase berthing capacity at PPN Prigi while ensuring vessel stability. Through a systematic analysis of various outrigger widths (1.5, 1.25, 1, and 0.75 meters), the study determined that a reduction to 1 meter maintains vessel stability as per HSC 2000 Annex 7 and Annex 749 (18) Ch3 design criteria. A 1-meter reduction in outrigger length can increase berthing efficiency by 66% for a standard 15-meter berth with 30-40 cm ship spacing. Consequently, the east dock of PPN Prigi can accommodate an additional 94 jukung vessels, raising the total capacity from 142 to 236. This research provides valuable insights for optimizing port infrastructure and enhancing the operational efficiency of the fishing community in Prigi.
