Abstract

Indonesia mengalami perkembanganan jumlah armada kapal hingga Agustus 2022 terdapat 4.906 kapal penumpang, 50.419 kapal ikan dan 44.645 kapal barang dibandingkan pada tahun 2017 jumlah armada hanya 27.567 kapal, tahun 2018 jumlah armada 29.928 dan meningkat menjadi 32.587. Dengan ini, para naval engineer melakukan inovasi salah satunya multi-hull seperti SWATH dan Trimaran. Penelitian ini bertujuan salah satu inovasi untuk mengetahui perbandingan hambatan trimaran conventional dengan kapal trimaran SWATH. Model kapal yaitu kapal dari penelitian dari jurnal validasi yang nanti akan divariasikan menjadi SWATH. Analisis hambatan dan perhitungan model ini menggunakan metode Computational Fluid Dynamic (CFD) dengan bantuan bantuan software ANSYS. Analisis perbandingan hambatan ini dilakukan terhadap hambatan total, hambatan gesek, hambatan viskositas, hambatan gelombang dan hambatan residu dengan kecepatan pada fr 0.1, 0.3, 0.5, 0.7 dan 0.9. Dari hasil yang didapatkan pada CFD, bahwa koefisien hambatan total (CT) dengan rata – rata selisih trimaran conventional side hull dengan SWATH side hull sebesar 11%, CF mendapat selisih nilai dengan rata – rata sebesar 8,4%, CW mendapat selisih nilai dengan rata – rata sebesar 2,3%, CV mendapat selisih nilai dengan rata – rata sebesar 1,3%. Hasil dari contour gelombang yang di dapat dari CFD menunjukkan bahwa trimaran SWATH memiliki bentuk contour gelombang lebih teratur dibandingkan trimaran conventional side hull, hal ini disebabkan dengan WSA (Wetted Surface Area) yang lebih kecil. Interferensi yang dihasilkan menunjukan perbandingan sebesar 0,07% yang dimana nilai terendah -0,0088.

Abstract

The maritime transportation sector contributes significantly to atmospheric emissions due to its reliance on fossil fuels, underscoring the need for more energy-efficient, environmentally friendly propulsion technologies. One promising solution is Wind-Assisted Ship Propulsion (WASP), which uses wind energy as a supplemental power source for vessel propulsion. Among various WASP technologies, wingsails have attracted attention for their rigid airfoil geometry and their ability to generate aerodynamic lift efficiently. This study aims to investigate the influence of wing sail shape and placement on aerodynamic performance, to identify an effective configuration for vessel applications. Computational Fluid Dynamics (CFD) simulations are conducted using k-  SST turbulence model. Two symmetric airfoil profiles, NACA 0012 and NACA 0015, are examined under angle of attack variations of 5°, 0°, 5°, 10°, 15°, and 20°. The wingsail is modeled in two installation configurations: midship and a combined midship-aft arrangement. Simulations are performed at wind speeds of 4 m/s, 10 m/s, 13.7 m/s, and 17.2 m/s, with aerodynamic performance evaluated based on the lift and drag coefficients. Based on the results, the NACA 0015 wingsail shows more stable aerodynamic behavior than the NACA 0012, while medium wind speeds in the range of 10–13.7 m/s offer the best balance between lift and drag. In addition, the midship–aft wingsail arrangement consistently generates higher lift than the single midship configuration, making the NACA 0015 wingsail with midship–aft placement the most suitable choice for fishing vessel applications.
