Abstract
Potensi sumber angin sebagian besar di daerah perairan dalam sehingga munculnya konsep untuk pengembangan teknologi turbin angin untuk wilayah lepas pantai. Oleh karena itu, perlu dilakukan analisa respon gerak pada Floating Wind Turbine tipe Spar dengan beberapa simulasi. Simulasi yang dilakukan pada Tugas Akhir ini adalah variasi sistem tambat, dan variasi tinggi sarat air. Struktur Floating Wind Turbine akan ditinjau dalam 6 derajat kebebasan. Proses analisa respon gerak FWT menggunakan bantuan software dengan metode frequency domain. Dari hasil tersebut diharapkan diperoleh konfigurasi struktur dengan sistem penambatan yang efektif mereduksi amplitudo gerak dan respon spektra struktur. Pengaruh Sistem Tambat Taut sangat signifikan mereduksi gerakan struktur pada semua mode gerakan yang ditinjau. Sistem Tambat Taut mampu mereduksi gerakan struktur rata-rata 73.86% sedangkan Sistem Tambat Catenary mampu mereduksi gerakan struktur rata-rata sebesar 22.30 %. Amplitudo gerakan struktur untuk semua mode gerakan yang ditinjau akan tereduksi seiring dengan penambahan tinggi sarat air. Konfigurasi model struktur Floating Wind Turbine Sarat 130 meter dengan Sistem Tambat Taut mengurangi amplitudo gerakan dan respon spektra struktur lebih baik dibandingkan konfigurasi lainnya pada semua mode gerakan yang ditinjau

Potential sources of wind mostly in deep sea so that the emergence of the concept to development of floating wind turbine technology for the offshore area. So that is need, analyzed motion response on Floating Wind Turbine type of Spar with some simulations. Simulations are conducted in this research are a variation of the mooring system, and draft. Besides, the direction of loading also vary at each simulation. Floating Wind Turbine structure will be reviewed in six degrees of freedom. Motion response analysis using statistical software with frequency domain methods. These results expected to be obtained by the structural configuration that effectively reduce the amplitude of structural motion and structural response.
Taut Mooring System significantly reduce structural motion on all modes of motion being reviewed. Taut Mooring Systems is able to reduce amplitude of motion structure of an average 73,86%. While the Catenary Mooring System is able to reduce motion structure of an average of 22,30%.
The amplitude of structural motion for all modes will be reduced with the addition of draft. Configuration structure model Floating Wind Turbine Draft 130 M with Taut Mooring System reduces the amplitude of structural motion and structural response is better than the other configurations
