Analyzing the Total Resistance and Wave Pattern of Purse Seine Vessels with Photovoltaic-Powered

Introduction

Analyzing the total resistance and wave pattern of purse seine vessels with photovoltaic-powered. Optimize traditional Indonesian purse seine vessels. Analyze total resistance & wave patterns of photovoltaic-powered catamaran hulls. Single chine geometry minimizes resistance, boosting efficiency & sustainability.

Abstract

With 64.97% of its territory consisting of sea, Indonesia is one of the world's largest maritime nations and produces approximately 8.02 million tons of fish annually. Traditional fishing vessels play a crucial role in supporting livelihoods, yet their design is often based on hereditary methods rather than hydrodynamic optimization. This study uses catamaran hull forms as a design reference to analyze the total resistance and wave patterns of purse seine vessels with photovoltaic-powered systems. Computational methods are employed to predict vessel performance efficiently. The resistance analysis applies the Slender Body approach and Savitsky's mathematical model, supported by comparative studies for validation. Particular attention is given to the influence of chine configurations on resistance characteristics and wave formation. Results indicate that the addition of chines increases the Froude number and contributes to reducing total resistance. Among the variations, single chine geometry demonstrates the lowest resistance, making it the most efficient configuration for catamaran fishing vessels. While chine modifications affect the wave pattern, the hull maintains a relatively clean wake distribution. These findings highlight the potential for improving vessel design through careful chine geometry optimization combined with computational modeling. The study underscores the importance of modern hydrodynamic analysis in advancing traditional fishing vessels toward higher efficiency and sustainability. Future research is recommended to incorporate more advanced computational approaches, such as Computational Fluid Dynamics (CFD), examine water-hull interactions and enhance vessel performance under operational conditions.

Review

This paper presents a timely and relevant analysis of total resistance and wave patterns for photovoltaic-powered purse seine vessels, focusing on catamaran hull forms in the context of Indonesia's vast maritime industry. The study addresses a critical gap by applying modern hydrodynamic optimization techniques to traditional fishing vessel design, which has historically relied on empirical, hereditary methods. By employing computational methods, specifically the Slender Body approach and Savitsky's mathematical model, supported by comparative validation studies, the authors aim to improve the efficiency and sustainability of these vital vessels. The integration of photovoltaic power systems highlights a forward-thinking approach to sustainable maritime practices. A key strength of the research lies in its specific investigation into the influence of chine configurations on vessel performance. The findings indicate that chine addition can increase the Froude number and effectively reduce total resistance, with the single chine geometry emerging as the most efficient configuration. This granular analysis provides practical design guidelines for engineers and naval architects. Furthermore, the observation that hull modifications maintain a relatively clean wake distribution, despite affecting wave patterns, underscores the potential for achieving improved efficiency without adverse environmental impacts from increased wave-making. The computational methodology offers an efficient means of predicting performance, which is crucial for rapid design iterations in a resource-constrained context. While the study offers valuable insights into improving traditional vessel design, it implicitly points to avenues for further refinement. The abstract itself recommends future research to incorporate more advanced computational approaches, such as Computational Fluid Dynamics (CFD), to examine complex water-hull interactions and enhance performance under operational conditions. This suggests that the current Slender Body and Savitsky models, while efficient, may have limitations in fully capturing the intricate hydrodynamics of chined catamaran hulls. A discussion on the specific validation methods and their scope would also strengthen the robustness of the comparative studies. Nevertheless, this work serves as an important stepping stone, emphasizing the crucial role of modern hydrodynamic analysis in moving traditional fishing fleets towards higher efficiency and sustainability.
