Abstract

Ekspansi Floating Solar Photovoltaic (FSPV) ke wilayah laut berpotensi mendukung pengembangan energi terbarukan di Indonesia, namun masih menghadapi tantangan akibat beban gelombang yang dapat meningkatkan respons gerak struktur dan gaya tambat. Penelitian ini menganalisis pengaruh variasi layout Floating Breakwater (FBW) terhadap respons hidrodinamika FSPV menggunakan model numerik. Layout yang dikaji terdiri dari I-shaped, L-shaped, dan U-shaped, dengan evaluasi berdasarkan Response Amplitude Operator (RAO), koefisien transmisi gelombang (Kt), dan tension mooring. Hasil menunjukkan bahwa pada kondisi eksisting tanpa pelindung, RAO maksimum terjadi pada surge sebesar 28,80 m/m, roll sebesar 13,31 deg/m, dan pitch sebesar 9,75 deg/m. Dari ketiga layout, konfigurasi U-shaped memberikan kinerja paling optimum dengan nilai Kt sebesar 0,70 pada heading 0°, 0,68 pada heading 30°, dan 0,64 pada heading 60°. Layout ini juga mampu menurunkan tension maksimum mooring dari 162,26 kN menjadi 120,17 kN atau sebesar 25,94%. Dengan demikian, layout U-shaped menjadi konfigurasi FBW paling efektif dalam mereduksi respons hidrodinamika dan gaya tambat FSPV.

The expansion of Floating Solar Photovoltaic (FSPV) systems into marine environments has strong potential to support renewable energy development in Indonesia, but it also faces challenges from wave loads that may increase structural motion and mooring forces. This study analyzes the effect of Floating Breakwater (FBW) layout variations on the hydrodynamic response of an FSPV system using numerical modeling. Three layouts were evaluated, namely I-shaped, L-shaped, and U-shaped, based on the Response Amplitude Operator (RAO), wave transmission coefficient (Kt), and mooring tension. The results show that, under the existing unprotected condition, the maximum RAO occurs in surge at 28.80 m/m, roll at 13.31 deg/m, and pitch at 9.75 deg/m. Among the three layouts, the U-shaped configuration provides the most optimum performance, with Kt values of 0.70 at 0° heading, 0.68 at 30° heading, and 0.64 at 60° heading. This layout also reduces the maximum mooring tension from 162.26 kN to 120.17 kN, corresponding to a 25.94% reduction. Therefore, the U-shaped FBW layout is the most effective configuration for reducing the hydrodynamic response and mooring tension of the FSPV system.
