Abstract

Meningkatnya tingkat polusi yang dihasilkan oleh kapal mendorong perlunya pengembangan teknologi yang mampu mengurangi dampak lingkungan dari sektor pelayaran. Penelitian ini menyajikan analisis penggunaan wingsail berbentuk persegi tunggal sebagai sistem propulsi bantu pada kapal tanker minyak berkapasitas 8.700 DWT, dengan tujuan mengevaluasi kinerja aerodinamika, kelayakan stabilitas kapal, serta kontribusinya terhadap pengurangan daya mesin utama. Simulasi numerik dilakukan untuk memperoleh koefisien lift dan drag pada tiga variasi aspect ratio (AR 2, AR 4, dan AR 6), di mana luas layar maksimum ditentukan berdasarkan batasan stabilitas dan diperoleh sebesar 289 m² melalui interpolasi linier dari hasil analisis stabilitas. Evaluasi stabilitas dilakukan pada empat loading condition dan titik pelayaran sepanjang rute Gresik–Bontang menggunakan kriteria kapal layar, yaitu K ≥ 1, GM ≥ 0.3 m, serta batas perbedaan LCG–LCB ≤ 0.5% LPP. Hasil analisis menunjukkan bahwa seluruh konfigurasi memenuhi kriteria stabilitas yang dipersyaratkan, dengan peletakan wingsail di midship memberikan karakteristik stabilitas paling baik. Dari sisi kinerja aerodinamis, konfigurasi AR 4 dengan ukuran span 34 m dan chord 8.5 m menghasilkan gaya dorong rata-rata terbesar sebesar 10911.5 N dan memberikan pengurangan daya mesin yang paling efektif. Hasil penelitian ini menunjukkan bahwa wingsail yang dirancang memiliki kinerja aerodinamis yang baik dan aman dari sisi stabilitas, sehingga berpotensi menjadi solusi praktis sebagai sistem propulsi bantu berbasis energi angin pada kapal tanker.

The increasing level of pollution generated by ships highlights the need for technological solutions to reduce the environmental impact of the maritime sector. This study presents an analysis of a single squared wingsail employed as an auxiliary propulsion system for an 8,700 DWT oil tanker, aiming to evaluate its aerodynamic performance, stability feasibility, and contribution to main engine power reduction. Numerical simulations were conducted to obtain lift and drag coefficients for three aspect ratios (AR 2, AR 4, and AR 6), while the maximum sail area was determined based on stability constraints and obtained as 289 m² through linear interpolation of stability analysis results. Stability assessments were carried out for four loading conditions and voyage waypoints along the Gresik–Bontang route using sail-assisted ship weather criteria, namely K ≥ 1, GM ≥ 0.3 m, and the longitudinal balance limit of LCG–LCB ≤ 0.5% LPP. The results indicate that all configurations satisfy the required stability criteria, with the midship placement of the wingsail providing the most favorable stability characteristics. In terms of aerodynamic performance, the AR 4 configuration, with a 34 m span and an 8.5 m chord, produces the highest average thrust of 10911.5 N and delivers the most effective engine power reduction. These findings demonstrate that the proposed wingsail design is both aerodynamically effective and stable, offering a practical solution for auxiliary wind-assisted propulsion on tanker vessels.
