Abstract

Fuel efficiency and stable engine performance are important issues in small diesel engines used for marine-related applications, such as auxiliary power units, generator sets, and small vessel systems. This study investigates the effect of injector pressure variation on the performance and fuel efficiency of a four-stroke single-cylinder diesel engine equipped with a Lateral Swirl Combustion System (LSCS) piston. The injector pressure was varied at 170, 180, and 190 bar, while the engine was tested at different speeds of 1000, 1200, 1300, and 1400 rpm under electrical loads of 2000, 3000, and 4000 W. The evaluated performance parameters included output power, torque, brake specific fuel consumption (BSFC), brake mean effective pressure (BMEP), and performance map characteristics. The results show that injector pressure significantly influenced the combustion performance and fuel utilization of the LSCS piston diesel engine. Among the tested conditions, the 190 bar injector pressure produced the best overall performance, with a maximum power of 2.72 kW, torque of 18.65 N·m, BSFC of 371.06 g/kWh, and BMEP of 1.95 bar. Compared with the 180bar setting, the 190bar injector pressure increased power by 1.87%, increased torque by 1.96%, reduced BSFC by 7.32%, and increased BMEP by 2.09%. The performance map also indicated that the 190bar setting provided the most favorable operating region, characterized by relatively low BSFC and higher BMEP. These findings suggest that injector pressure optimization combined with LSCS piston geometry can improve combustion effectiveness and fuel efficiency in small diesel engines for marine-related applications.

Abstract

This study investigates the hydrodynamic resistance characteristics of a forward-facing reverse-V stepped planing hull using a Computational Fluid Dynamics (CFD) approach under high-speed planing conditions. Five reverse-V angle configurations consisting of 180°, 165°, 150°, 135°, and 120° were evaluated at a constant speed of 27 knots (13.9 m/s) using the Reynolds-Averaged Navier–Stokes (RANS) and Volume of Fluid (VOF) methods. Unlike conventional aft-facing stepped hulls, the proposed reverse-V geometry redirects the flow inward toward the forward centerline region beneath the hull bottom, modifying pressure redistribution, cavity interaction, and wetted surface formation. The numerical simulations employed a Poly-Hexacore meshing strategy and demonstrated stable convergence behavior with excellent mesh-quality characteristics. The results show that the 165° and 150° configurations increased hydrodynamic resistance due to stronger turbulence interaction and larger wetted surface development around the step region. In contrast, sharper reverse-V configurations improved hydrodynamic performance through stronger inward pressure convergence and more compact cavity formation. The 120° configuration generated the lowest resistance value of 7463.052 N and achieved the highest resistance reduction of 2.02% compared to the baseline model.

Abstract

The operational efficiency and safety of patrol vessels critically depend on minimizing hydrodynamic resistance and enhancing seakeeping performance. This study explores the effect of stern foils with different NACA airfoil sections on a patrol vessel. Employing Computational Fluid Dynamics (CFD), we assessed water resistance in calm conditions and seakeeping traits in regular head seas. Based on the results obtained, the total resistance value (RT) without stern foil shows a value of 202,112 N. Findings show that stern foils lead to a considerable reduction in total resistance, with the NACA 2412 profile achieving the greatest reduction at 14.85%, followed by NACA 64-212 (14.70%) and NACA 4412 (11.67%) at 20 knots and Fn 0.418. Additionally, seakeeping assessments revealed a significant mitigation of pitch and heave motions across all foil designs, notably a marked decrease in pitch Response Amplitude Operator (RAO) at the dominant frequency of 0.13 Hz. This work provides significant contributions to the optimization of patrol vessel design through advanced hydrodynamic additions, contributing to better fuel economy and greater operational stability in challenging maritime environments.

Abstract

Floating jetties are increasingly used in marine infrastructure because of their adaptability to water-level fluctuations and ease of installation. Recently, High-Density Polyethylene (HDPE) has attracted attention as an alternative construction material due to its corrosion resistance, lightweight characteristics, and impact-absorption capability. However, information regarding the structural behaviour of HDPE floating jetties under ship collision loads remains limited. Therefore, this study aims to investigate the structural response and deformation characteristics of an HDPE floating jetty subjected to vessel berthing impacts. The analysis was conducted using the Finite Element Method (FEM). A floating jetty with dimensions of 10 m × 2.5 m × 1.5 m was modelled and subjected to collision loads generated by a 5-ton vessel approaching at a 20° berthing angle. Berthing energies were calculated according to PIANC recommendations and converted into equivalent static impact loads under favourable, moderate, and unfavourable berthing conditions. The calculated berthing energies were 88.4 J, 198.9 J, and 353.6 J, corresponding to impact loads of 15.2 kN, 22.7 kN, and 30.2 kN, respectively. The maximum deformations obtained from the FEM analysis were 12.11 mm, 18.21 mm, and 24.22 mm. The results showed a nearly linear relationship between impact load and structural deformation, indicating stable elastic behaviour throughout the investigated loading range. Even under the most severe berthing condition, the maximum deformation represented only 0.24% of the jetty length. The study demonstrates that HDPE floating jetties possess adequate impact resistance and deformation capacity for small-vessel berthing operations. These findings provide additional insight into the application of HDPE as a structural material for floating marine infrastructure subjected to collision loading.

Abstract

The integration of renewable energy systems in fishing vessels has increasingly attracted attention as an alternative approach to improving operational sustainability and reducing dependency on conventional energy sources. However, additional equipment installed above the deckhouse may influence vessel stability and operational performance. This study aims to investigate the effect of solar panel installation on the deckhouse of a 30 GT fishing vessel in terms of stability characteristics and fishing operational capability. The analysis was conducted using secondary vessel data and numerical simulations through Maxsurf software. Stability performance was evaluated using the A.N. Krylov method with verification based on International Maritime Organization intact stability criteria, while seakeeping performance was assessed using strip theory combined with the Joint North Sea Wave Project wave spectrum under various loading and wave conditions. The results indicate that solar panel installation slightly changes the vessel’s weight distribution but does not significantly affect stability performance, as all loading conditions satisfy the required stability criteria. Seakeeping analysis further shows that vessel performance is strongly affected by wave conditions, with the most favorable operational performance achieved at wave heights below 2 m. These findings demonstrate that solar panel integration can be implemented on fishing vessel deckhouses without significantly compromising vessel safety and operational performance under appropriate environmental conditions.

Abstract

Effective energy management is critical for maximizing the efficiency and environmental benefits of hybrid propulsion systems (HPS) in ships. This systematic review evaluates various advanced energy management strategies (EMS) applied to marine HPS, focusing on model predictive control (MPC), equivalent consumption minimization strategy (ECMS), sequential quadratic programming (SQP), predictive power-split, and rule-based approaches. Based on an analysis of recent international literature, findings indicate that MPC-based EMS improves fuel efficiency by 10-20% and extends battery life through optimal power distribution under dynamic load conditions. Meanwhile, ECMS reduces equivalent fuel consumption by up to 25% under varying operational cycles. Predictive power-split algorithms achieve 15-20% energy savings by anticipating propulsion load changes up to 30 minutes in advance. Compared to conventional rule-based systems, advanced EMS reduces CO₂ emissions by 20-45% and NOx emissions by 20-60%, especially during harbor maneuvering and low-speed cruising. However, challenges remain, including high computational demands for real-time MPC, dependence on accurate load prediction models, and the lack of standardized interoperability protocols. This review concludes that integrating artificial intelligence and digital twins into EMS represents the most promising research direction. For ferries, patrol boats, and research vessels, implementing MPC or ECMS with adaptive tuning can significantly enhance operational performance while complying with IMO EEDI and CII regulations.

Abstract

Ship propulsion has evolved significantly over thousands of years, from the use of simple paddles around 40,000 BCE to modern advanced systems driven by diesel engines, steam turbines, nuclear reactors, electric motors, and wind power. This systematic literature review aims to synthesize current knowledge on ship propulsion systems, highlighting technological advancements, energy efficiency, and environmental impacts. By analyzing various studies through a qualitative approach and the PRISMA framework, this research identifies three main themes: advanced propulsion systems, propulsion optimization, and hybrid technology integration. The results show that while diesel engines remain dominant, Integrated Full Electric Propulsion (IFEP) systems coupled with induction motors and Permanent Magnet Synchronous Motors (PMSMs) offer higher efficiency and lower emissions. Furthermore, wind-assisted technologies, such as Dynarigs, Flettner rotors, and towing kites, demonstrate great potential to reduce fuel consumption by up to 50% compared to conventional systems, while nuclear propulsion enables higher operational speeds with minimal fuel replenishment. However, key challenges remain, including high initial investment costs, control system complexity, and regulatory acceptance. In conclusion, the future of ship propulsion lies in hybrid configurations that optimize the combination of electric and wind power, supported by predictive computational models and fault-tolerant control to achieve cleaner, safer, and more sustainable maritime operations. Interdisciplinary collaboration is essential to accelerate this transition.

Abstract

Stringent IMO regulations targeting a 40% GHG reduction by 2030 and net-zero by 2050 have driven the maritime industry to adopt cleaner technologies, as conventional diesel propulsion often operates inefficiently with high fuel consumption and emissions. This paper presents a descriptive-comparative literature review of hybrid propulsion systems for ships, analyzing peer-reviewed journals published in the last five years. The study examines system configurations (series, parallel, series-parallel), key components (diesel engines, fuel cells, batteries, supercapacitors), and energy management strategies (EMS), with a focus on artificial intelligence-based approaches such as Deep Reinforcement Learning (DRL) and Nonlinear Model Predictive Control (NMPC). The findings indicate that hybrid systems can improve energy efficiency by 15–30% and significantly reduce CO₂, NOₓ, and SOₓ emissions compared to conventional systems, especially during zero-emission port operations. Advanced EMS, particularly DRL algorithms like Proximal Policy Optimization (PPO), enable real-time multi-objective optimization that balances fuel economy, battery health, and component longevity. However, challenges remain, including high initial investment costs, optimal sizing of hybrid energy storage systems, and limited charging infrastructure. This review concludes that despite these barriers, the convergence of intelligent EMS, falling battery prices, and tightening environmental regulations positions hybrid propulsion as a key technology for sustainable maritime transportation, with future potential from waste-heat recovery systems and alternative fuels.

Abstract

This study aims to analyze the effect of variations in the side skeg angle on the total resistance and motion response of a barge. The research subjects consisted of a barge model without a skeg and a barge model with a triple-skeg configuration at side skeg angles of 140°, 150°, 160°, and 180°. Numerical simulations were conducted using Maxsurf Resistance software to obtain total resistance values and the Hydrodynamic Diffraction method to evaluate sway and yaw motion responses. Resistance tests were performed under two loading conditions full load and light load with a speed range of 2 to 6 knots. Seakeeping analysis was performed at a speed of 6 knots with regular waves 1 meter high and wave incidence angles of 0°, 45°, 90°, 135°, and 180°. The results of the study show that the addition of a skeg increases total resistance by a relatively small percentage, namely 1.68% - 1.74% under full-load conditions and 2.60% - 2.83% under light-load conditions. From a seakeeping perspective, the addition of a skeg tends to slightly increase the sway response but effectively reduces the yaw response, particularly at a transverse wave angle of 90°. Based on the balance between increased resistance and reduced yaw response, the 150° side skeg configuration can be considered the most balanced option for improving the barge’s directional stability without introducing significant additional resistance.
