Abstract

Hydrodynamics of a floating structure is of interest from offshore and coastal engineers who develop the wave energy converters and utilize the marine space resources. Recently, Rim [1-3] proposed an exact DtN (Dirichlet-to-Neumann) artificial boundary condition in order to solve three dimensional wave-structure interactions or wave motion over piecewise topographies numerically. This paper is concerned with another artificial boundary condition or so-called NtD (Neumann-to Dirichlet) boundary condition in order to solve water wave diffraction and independent radiation by a buoyant body. A virtual cylindrical surface enclosing the floating body is chosen as a boundary on which an exact NtD map is analytically derived from a solution of the exterior subregion and then it is specified as a boundary condition in order to solve the interior problem. The present model shows good accuracy through the comparison with the DtN approach and suggests the escalated results for the effects of heading angle of incident wave and draft of a buoyant chamfer box.

Abstract

Lake Sunter, an man-made lake built since the 1970s and covering approximately 33 hectares, is commonly referred to as Lake Podomoro. Positioned as an urban recreational space, its scenic vistas offer potential for diverse water-based activities. In order to increase tourist engagement with the lake, it is imperative to diversify the available attractions. Among these attractions, tourist boats emerge as a viable option to capture public interest. Accordingly, this study attempts to design a catamaran tour boat equipped with motorcycle propulsion, tailored for operation on Lake Sunter. In the first stage, the primary dimensions of the catamaran vessel are determined using the linear regression method, resulting in dimensions of L = 3.2m, H = 1.15m and T = 0.4m, with a passenger capacity of 3 persons. The ship's stability is then assessed in accordance with the criteria of the IMO A.749 (18) Code On Intact Stability, Chapter 3, which applies to all ship designs. This assessment includes Load Case I and Load Case II conditions to determine the stability of the ship under different scenarios.

Abstract

Pelra Pinisi ships are increasingly being abandoned in freight transportation to 3TP (disadvantaged, outermost, remote, and border) regions, which are now predominantly served by perintis vessels. Unlike these perintis vessels, Pelra Pinisi ships do not receive similar government subsidies and face limitations in navigating currents and sea waves. This study proposes the revitalization of Pelra Pinisi ships through the implementation of a soft sail design to reduce emissions and fuel consumption, optimal route determination using a solver, and subsidy calculations to ensure competitiveness. The study was conducted in East Nusa Tenggara, covering six perintis routes and 24 ports. Survey data indicate that traditional Pelra vessels typically range from 30 to 40 meters in length. The proposed new designs include ships of 300 GT, 200 GT, and 100 GT, with lengths of 35.00 m, 22.75 m, and 17.50 m, respectively, and speeds of 12.5 knots, 7.8 knots, and 6.0 knots. Emission reductions were observed on the Kupang–Ndao and Kupang–Naikliu routes by 0.89%. The 300 GT vessel is optimal for the Kupang–Ndao and Labuan Bajo–Maumbawa routes, the 200 GT vessel for the Sabu–Raijua and Waikelo–Labuan Bajo routes, and the 100 GT vessel for several other routes.

Abstract

Effective time management is crucial in the shipping business at ports, ensuring smooth operations from a ship’s arrival to its departure. Delays in port can disrupt sailing schedules, leading to inefficiencies in logistics and increased operational costs. This study aims to predict the duration of a ship's stay in port, focusing on container and general cargo ships. Accurate predictions can help optimize scheduling and resource allocation. The research applies machine learning techniques, utilizing historical arrival and departure data from Tanjung Priok Port for 2022 and 2023. Four algorithms were evaluated: Random Forest, Linear Regression, K-Nearest Neighbors (KNN) Regression, and Support Vector Machine (SVM). Results indicate that Linear Regression provides the most accurate predictions, outperforming other models in terms of Mean Absolute Error (MAE), Mean Squared Error (MSE), and Root Mean Squared Error (RMSE). Additionally, its coefficient of determination (R2) is closest to one, confirming its reliability for forecasting ship turnaround times.

Abstract

Over the decades, advancements in computer technology have significantly contributed to the development of numerical methods, including computational fluid dynamics (CFD). CFD encompasses two primary approaches: mesh-based and mesh-free methods. While mesh-based methods are well-established and widely used for analyzing free-surface flows, such as ship resistance, mesh-free methods like smoothed particle hydrodynamics (SPH) have gained traction in real-world engineering applications. Despite its growing use, limited research has explored the application of SPH to ship resistance analysis. This study investigates the total ship resistance of a planing hull using the open-source SPH solver DualSPHysics. The research focuses on analyzing spray patterns and complex flow dynamics around the hull. DualSPHysics typically employs dynamic boundary conditions (DBC) as its standard boundary definition method. However, this study utilizes an advanced implementation of DBC, known as Modified Dynamic Boundary Conditions (mDBC), in conjunction with Project Chrono for enhanced simulation accuracy. The results demonstrate that SPH provides acceptable accuracy when compared to the Strip theory approach. Additionally, key parameters such as total force, sinkage, and trim are effectively reproduced using Project Chrono. This research highlights the potential of SPH, particularly with advanced boundary conditions, for ship resistance analysis and contributes to the growing body of knowledge in this field.

Abstract

Whiteleg shrimp (Litopenaeus vannamei) is a major aquaculture commodity in Indonesia, valued for its resilience, rapid growth, and economic potential. However, water quality remains a critical factor influencing shrimp health, particularly their immune response. This study aimed to examine the correlation between water quality parameters and the immune responses of L. vannamei cultivated in Probolinggo, East Java. A descriptive quantitative method was employed, using simple random sampling across three pond sites. Water parameters measured included temperature, pH, dissolved oxygen (DO), salinity, ammonia, nitrate, total suspended solids (TSS), and total dissolved solids (TDS). Immune response indicators such as Total Hemocyte Count (THC), differential hemocyte count (DHC), and phagocytic activity were analyzed. Canonical Correspondence Analysis (CCA) was used to assess correlations. The results revealed significant relationships between water quality and shrimp immune parameters, highlighting the importance of proper environmental management in shrimp farming. These findings provide insights for improving productivity and disease resistance in sustainable aquaculture systems.

Abstract

The motor is a crucial component of a ship's propulsion system, playing a significant role in facilitating smooth maritime transportation operations. Various factors, including dynamic loads, speed variations, and unstable marine environmental conditions influence the performance of the propulsion motor. Under dynamic conditions, the ship's propulsion motor encounters challenges such as load fluctuations, vibrations, and other disturbances that can affect its efficiency and operational lifespan. Consequently, real-time monitoring of the motor's condition has become an urgent necessity to detect potential damage early and ensure the safety and reliability of the ship's operations. This study aims to develop a condition monitoring system for ship propulsion motors using nonlinear acoustic signals. These signals will be processed using appropriate algorithms for nonlinear signals' characteristics. The Short Time Fourier Transform (STFT) is identified as a suitable algorithm for processing nonlinear signals. The filtered signal results will provide insights into the condition of the ship's propulsion motor. Given the influence of vibrations and non-engine noise, careful consideration must be given to sensor placement to achieve high monitoring accuracy. The Completely Randomized Design (CRD) approach will be employed to determine the optimal sensor placement. Through precise signal processing, meticulous spectral analysis, and optimal sensor positioning, accurate information can be obtained. The research findings indicate that the motor monitoring system achieved an accuracy rate of 100% with the sensor positioned 110 cm from the test motor body.

Abstract

The stress value of the piping system will change during operating conditions. The stress value affects the integrity of the piping system. Excessive stress will cause deformation and damage to the piping system. The operating condition parameters of the piping system are temperature and pressure. The High-Energy Piping (HEP) system is subjected to high pressures and temperatures, which can cause significant stresses on the piping components. So stress analysis needs to be carried out to ensure that the piping system has strength and flexibility. The Cold Reheat Pipe (CRP) steam line is one of the High-Energy Piping Systems in this steam power plant. CRP consists of CRP BS 130 and CRP BS 131. This paper is about evaluating the stress due to operating loads in 2024 (temperature, pressure, and remaining thickness) for steam lines on the high-energy piping system using the finite element method and refers to ASME B31.1. The output stress values in the piping system in this paper consist of stress due to sustained load, stress due to thermal load, and hoop stress. The CRP BS 130 modeling results show the maximum stress due to sustained load (166.6 kg/cm2), the maximum stress due to the thermal load (112.8 kg/cm2), and the maximum hoop stress (855.6 kg/cm2). The CRP BS 131 modeling results show the maximum stress due to sustained load (974.2 kg/cm2), the maximum stress due to the thermal load (123.5 kg/cm2), and the maximum hoop stress (938.9 kg/cm2). The results of the stress evaluation due to the operating load were still below the allowable stress and are still permitted by the ASME B31.1 Code.

Abstract

The shipbuilding industry is characterized by high-risk working environments, making the implementation of Occupational Health and Safety Management Systems (OHSMS) critically important. While OHSMS has traditionally been regarded as a tool for regulatory compliance, recent studies suggest can also function as a strategic asset that enhances a company's market positioning. This paper aims to investigate the integration of OHSMS with marketing strategies in the shipbuilding industry and evaluate their combined impact on productivity. A systematic literature review was conducted, analyzing 40 selected sources including peer-reviewed journal articles, industry reports, and regulatory frameworks. The review reveals that companies that strategically align their safety management systems with marketing communications tend to achieve multiple benefits, such as improved safety performance, stronger client trust, enhanced brand reputation, and increased productivity. These findings support the growing perspective that occupational health and safety can serve not only as an internal operational necessity but also as a competitive differentiator. The study contributes to the literature by highlighting the untapped potential of safety performance as a component of industrial marketing and suggests that cross-functional collaboration between health and safety and marketing teams can deliver both operational and reputational advantages.
