Abstract

Reducing fuel consumption in fishing vessels has become an important issue in improving the efficiency and sustainability of maritime operations, particularly for small and medium-scale fisheries. One potential approach is the integration of wind-assisted propulsion systems such as wingsails. However, the addition of structures above the deck may influence vessel stability and motion responses in waves. This study evaluates the effect of wingsail integration on the seakeeping performance and intact stability of a fishing vessel operating in Benoa, Bali. The reference vessel has principal dimensions of LOA 33.50 m, LPP 29.65 m, breadth 7.95 m, depth 4.06 m, draft 2.90 m, and displacement 415.6 tons. Analysis is conducted using Maxsurf Stability for intact stability assessment and Maxsurf Motion for seakeeping analysis. The seakeeping evaluation considers wave headings of 90°, 135°, and 180° with vessel speeds of 6, 8, and 10 knots, while sea conditions are derived from Beaufort scale conversion. Vessel motions are assessed using RMS, MSI, and MII according to STANAG 4154, while stability is evaluated under departure, fishing ground, and arrival load cases based on IMO Intact Stability Criteria.

Abstract

Kejadian slamming pada kapal frigate merupakan respon transien yang dihasilkan dari lambung haluan kapal saat mengangguk atau menghempas ke bawah, yang umumnya menginduksi frekuensi rendah terutama pada moda pertama frekuensi alami badan kapal. Paper ini membahas metode pendekatan perhitungan frekuensi natural badan kapal frigate moda pertama dengan metode Kumai yang telah berhasil diaplikasikan juga pada kapal-kapal niaga. Berdasarkan hasil penelitian ini diperoleh bahwa perhitungan pendekatan frekuensi natural pada kapal dengan metode Kumai dapat pula diaplikasikan pada kapal jenis frigate.

Abstract

Salah satu faktor tidak terkirimnya data dari buoy ke stasiun data di darat untuk mengantisipasi potensi terjadinya tsunami karena adanya vandalisme pada buoy seperti; digunakan sebagai tambat kapal bahkan sampai dengan pencurian beberapa atau seluruh bagian dari buoy tersebut. Untuk menekan vandalisme atau pencurian dari buoy tersebut maka buoy disarankan beroperasi di bawah permukaan air laut sehingga tidak menarik perhatian kapal yang melintasi daerah tersebut. Untuk merancang buoy tersebut perlu dilakukan kajian baik dari segi hidrodinamis, kekuatan strukturnya dan proses produksi serta dengan pengujian prototype, dari kajian tersebut maka didapatkan desain buoy skala penuh yang akan dioperasikan di laut. Hasil pengujian menunjukkan bahwa kemampuan apung dan kekedapan dari prototype sub_buoy secara umum selama 14 (empat belas) hari di kedalaman 1 meter dari permukaan air di kolam tetap mempunyai daya apung yang direncanakan dengan sarat operasional 1,2 m.

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.
