Abstract

English

Research on the flow around the SPAR model was carried out with the aim of finding out how much effect the flow has on the SPAR structure used in offshore wind turbines. SPAR is a type of floating structure that can usually be used in deep seas and is an effective and reliable structure in terms of construction. Spar has the advantage that the buoyancy point (KB) is above the gravity point (KG), thus providing good stability. However, there are still obstacles to the use of SPAR structures in the deep sea, especially when environmental conditions are extreme, where SPAR structures are not able to reduce currents at a certain speed level. Then, this research aims to test the SPAR model with a four vertical plate (4VP) configuration system which is then modeled using Computational Fluid Dynamics (CFD) based numerical modeling which aims to investigate the flow around the SPAR in terms of flow velocity. Especially at certain flow velocity levels, the velocity is chosen carefully at each level starting from: V1 = 0.611m/s, V2 = 6.114, V3 = 61.144, V4 = 611.438. The addition of vertical plates to the bottom construction of the SPAR has a role in dampening the flow and also turbulent effects due to current impacts.

Penelitian mengenai aliran di sekitar model SPAR dilakukan dengan tujuan untuk mengetahui seberapa besar efek aliran terhadap struktur SPAR yang di gunakan pada offshore wind turbine. SPAR merupakan jenis floating structure biasanyadapat digunakan di laut dalam dan menjadi struktur yang efektif dan dapat diandalkan dari segi konstruksi. Spar memiliki keunggulan yang mana letak titik buoyancy (KB) berada di atas titik gravitasi (KG) sehingga memberikan stabilitas yang baik. Namun penggunaan struktur SPAR di laut dalam juga masih terdapat kendala terkhusus Ketika kondisi lingkungan yang ekstrim, yang mana struktur SPAR yang belum mampu meredam arus pada tingkat kecepatan tertentu. Kemudian pada penelitian ini bermaksud untuk menguji model SPAR dengan sistem konfigurasi empat pelat vertical (4VP) yang kemudian dimodelkan dengan pemodelan numerik berbasis Computational Fluid Dynamics (CFD) yang bertujuan untuk menginfestigasi aliran sekitar SPAR yang ditinjau dari kecepatan aliran. Terutama pada tingkat kecepatan aliran tertentu, kecepatan dipilih dengan cermat disetiap tingkatannya mulai dari: V1 = 0.611m/s, V2 = 6.114, V3 = 61,144, V4 = 611,438. Penambahan pelat vertikal pada konstruksi bawah SPAR memiliki peran dalam meredam aliran dan juga efek turbulen akibat hantaman arus.
