Abstract

Rotor flettner merupakan salah satu teknologi efektif yang memanfaatkan tenaga angin untuk menghasilkan tenaga penggerak pada aplikasi kelautan. Rotor flettner berbentuk silinder yang berputar dan dapat menghasilkan gaya angkat aerodinamis karena efek magnus. Teknologi rotor flettner pada penelitian ini diaplikasikan pada kapal tanker milik Pertamina (PERSERO). Sebagai BUMN yang bergerak di sektor minyak dan gas tentu membutuhkan kapal tanker yang ramah konsumsi bahan bakar. Untuk pemodelan kapal dan perhitungan hambatan dibantu dengan Maxsurf, kemudian simulasi dari rotor flettner digunakan pendekatan dengan metode CFD (Computational Fluid Dynamic) dibantu Ansys Fluent. Sudut angin yang digunakan adalah 0°, 60°, 90°, dan 120°. Berdasarkan hasil perhitungan efisiensi bahan bakar, penambahan 5 rotor flettner pada kapal mampu menghemat bahan bakar pada mesin utama sebesar 122,69 kg/h atau 17,8% pada sudut angin 60°, 168,1 kg/h atau 24,4% pada sudut angin 90°, dan 147,66 kg/h atau 21% pada sudut 120°. Pengaruh stabilitas kapal akibat penambahan rotor flettner pada kapal masih memenuhi kriteria stabilitas IMO, Intact Stability Code A.179.18 dan weather criteria untuk sail-assisted ship.

Flettner rotor is one of the effective technologies that utilize wind energy to generate driving energy in marine applications. Flettner rotor is cylindrical in shape that rotates and can generate aerodynamic lift due to the magnus effect. Flettner rotor technology in this study was applied to a tanker owned by Pertamina (PERSERO). As a BUMN engaged in the oil and gas sector, it certainly requires a tanker that is friendly to fuel consumption. For ship modeling and resistance calculations assisted by Maxsurf, then testing of the flettner rotor used an approach with the CFD (Computational Fluid Dynamic) method assisted by Ansys Fluent. The wind angles used are 0°, 60°, 90°, and 120°. Based on the results of fuel efficiency calculations, the addition of 5 flettner rotors to the ship can save fuel on the main engine by 122.69 kg/h or 17.8% at a wind angle of 60°, 168.1 kg/h or 24.4% at a wind angle of 90°, and 147.66 kg/h or 21% at a wind angle of 120°. The effect of ship stability due to the addition of flettner rotor on the ship still meets the IMO stability criteria, Intact Stability Code A.179.18 and weather criteria for sail-assisted ships.
