Abstract

This study aims to analyze the effect of bow angle variations on the total resistance of a 216 GT Self-Propelled Oil Barge (SPOB) using the Computational Fluid Dynamics (CFD) method. The efficiency of bow design significantly affects a vessel’s hydrodynamic performance, particularly at the cruising speed of 5 knots. In this research, three bow angle variations—49°, 42°, and 39°—were modeled and Holtrop Metode and CFD Metode . The simulation results show that bow angle modification has a significant impact on the ship’s resistance. The 39° bow angle yielded the lowest resistance at 3.995 kN, followed by 42° at 4.135 kN, and 49° at 4.241 kN, based on CFD simulation results. Therefore, the 39° bow angle is recommended as the optimal design for improving voyage efficiency and reducing fuel consumption.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh variasi sudut haluan terhadap hambatan total kapal Self-Propelled Oil Barge (SPOB) 216 GT menggunakan metode Computational Fluid Dynamics (CFD). Efisiensi desain haluan sangat mempengaruhi performa hidrodinamis kapal, terutama pada kecepatan jelajah 5 knot. Dalam studi ini, dilakukan modifikasi haluan dengan tiga variasi sudut, yaitu 49°, 42°, dan 39°, serta dilakukan pemodelan dan simulasi numerik menggunakan  Metode CFD. Hasil simulasi menunjukkan bahwa modifikasi sudut haluan berpengaruh signifikan terhadap nilai hambatan kapal. Sudut haluan 39° menghasilkan nilai hambatan paling rendah sebesar 3,995 kN, diikuti oleh 42° sebesar 4,135 kN dan 49° sebesar 4,241 kN berdasarkan simulasi CFD. Dengan demikian, sudut haluan 39° direkomendasikan sebagai desain optimal untuk meningkatkan efisiensi pelayaran dan mengurangi konsumsi bahan bakar
