Abstract

Turbin angin lepas pantai merupakan salah satu teknologi yang bisa dijadikan solusi untuk energi baru terbarukan. Turbin angin memanfaatkan energi kinetik angin yang mengenai bilah turbin kemudian mengonversinya menjadi energi listrik. Penilitian ini akan membahas mengenai gerak global struktur floating offshore wind turbine tipe SPAR dalam kondisi parking dan operation. Analisis dilakukan secara couple dengan menggunakan bantuan software open source FAST v.8 code. Hasil analisis disajikan dalam spektra respon pada seluruh mode gerak surge, sway, heave, roll, pitch dan yaw. Pada saat struktur dalam kondisi parking hasilnya mode gerak yang paling signifikan perbedannya karena perbedaan variasi kecepatan angin adalah sway dan heave dengan semakin besar nilai kecepatan angin yang mengenai struktur, nilai puncak spektra responnya semakin besar. Sedangkan pada kondisi operation pada mode gerak surge, putaran rotor akibat beban kecepatan angin 3 mps menghasilkan nilai puncak spektra respons tertinggi. Kemudian untuk mode gerak sway dan roll, semakin cepat putaran rotor menghasilkan nilai puncak spektra respons paling kecil. Sedangkan untuk mode gerak heave, pitch dan yaw semakin cepat putaran rotor membuat nilai puncak spektra respons paling tinggi. Hasil analisis gaya tarik tali tambat menunjukkan gaya tarik tali maksimum pada kondisi parking besarnya 1200 kN sedangkan pada kondisi operation besarnya 1622 kN. Secara kesuluruhan respons FOWT tipe SPAR dalam kondisi parking memberikan respon lebih tinggi pada puncak spektra responsnya daripada kondisi operation, kecuali pada mode gerak heave.==================================================================================================================
Offshore wind turbines are technology that can be used as a solution for new renewable energy. Wind turbine use kinetic energy of wind that hits the blade then converts it into electrical energy. This research discuss the global motion performance of a floating offshore wind turbine SPAR type in the parking and operation condition. That analysis using software FAST v.8 codes as a coupled. The results of the analysis are presented in the spectral reponses in motion mode surge, sway, heave, roll, pitch dan yaw. The results for parking condition is the most significant difference of motion mode due to differences wind speed variations are sway and heave with the greater the wind speed value regarding the structure, the peak value of the spectral response is greater. While for operation condition the surge motion mode due to load 3 m/s wind speed produce the peak spectral value. Then for sway and roll motion modes, the faster rotor rotation produces the smallest spectral response value. For the heave, pitch, and yaw motion mode the faster rotor rotation makes the peak value of the spectral response. The results of the mooring line tension for parking condition is 1200 kN while in operation condition is 1622 kN. Overall, the FOWT SPAR type response in the parking condition gives a higher response to the peak of the spectral response than the operation conditions, except the heave motion mode.
