Abstract

English

This research discusses the SPAR offshore wind turbine, a floating foundation turbine used for wind power generation in the deep sea. SPARs are designed with a large-diameter vertical floating cylinder weighted at its lower end, creating a structure that is less responsive to wind, waves, and currents. SPAR foundations have advantages in deep water due to their low center of mass, simple ballast stabilization, and high stability. The purpose of this research is to gain a deeper understanding of the fluid flow occurring around the SPAR, which impacts the performance and stability of the offshore wind turbine. This research will focus on CFD (computational fluid dynamics)-based numerical modeling analysis with the help of 3D analysis software ANSYS by considering several variations of fluid flow velocity to identify the pressure, velocity, and changes in fluid flow around the SPAR. The results of this study are expected to help in reducing the risk of SPAR foundation damage, improving turbine stability, and overall increasing the efficiency of offshore wind energy generation. This research has positive implications for reducing the environmental impact of energy generation compared to traditional fossil fuel sources.

Bahasa Indonesia

Penelitian ini membahas mengenai SPAR offshore wind turbine, sebuah turbin pondasi terapung yang digunakan untuk pembangkitan listrik tenaga angin di laut dalam. SPAR di desain dengan silinder apung vertikal berdiameter besar yang diberi pemberat di ujung bawahnya, menciptakan struktur yang kurang responsif terhadap angin, gelombang, dan arus. Pondasi SPAR memiliki keunggulan di perairan dalam karena pusat massanya yang rendah, stabilisasi pemberat yang sederhana, dan stabilitas yang tinggi. Tujuan dari penelitian ini adalah untuk mendapatkan pemahaman yang lebih mendalam mengenai aliran fluida yang terjadi di sekitar SPAR, yang berdampak pada kinerja dan stabilitas turbin angin lepas pantai. Penelitian ini akan berfokus pada analisis pemodelan numerik berbasis CFD (Computational Fluid Dynamics) dengan bantuan software analisis 3D yaitu ANSYS dengan pertimbangan beberapa variasi kecepatan aliran fluida untuk mengidentifikasi tekanan, kecepatan, dan perubahan aliran fluida sekitar SPAR. Hasil dari penelitian ini diharapkan dapat membantu dalam mengurangi risiko kerusakan pondasi SPAR, meningkatkan stabilitas turbin, dan secara keseluruhan meningkatkan efisiensi pembangkitan energi listrik tenaga angin lepas pantai. Penelitian ini memiliki implikasi positif dalam pengurangan dampak lingkungan dari pembangkitan energi dibandingkan dengan sumber bahan bakar fosil tradisional.
