Abstract

Transisi menuju energi terbarukan dipercepat dengan teknologi seperti Floating Photovoltaic (FPV), yang menggunakan panel surya pada pengapung di permukaan air. Meskipun inovatif, FPV menghadapi tantangan stabilitas dan daya tahan akibat pengaruh angin, gelombang, dan arus laut. Penelitian ini menganalisis pengaruh variasi jumlah mooring lines dan arah gelombang terhadap respon hidrodinamik pada FPV. Menggunakan catenary mooring system yang terdiri dari jangkar, tali tambat, pengapung, dan konektor, studi ini mengevaluasi berbagai konfigurasi untuk menemukan solusi optimal yang memastikan stabilitas terbaik. Simulasi numerik berbasis Boundary Element Method (BEM) digunakan untuk mempelajari respon dinamis FPV terhadap berbagai kondisi lingkungan, dengan fokus pada enam derajat kebebasan gerakan: Surge, Sway, dan Yaw. Hasil simulasi menunjukkan bahwa konfigurasi mooring Case 3 secara konsisten memberikan redaman terbaik terhadap gerakan surge, sway, dan yaw pada berbagai kondisi gelombang. Temuan ini memperkuat pentingnya pemilihan konfigurasi tambat yang tepat dalam meningkatkan kestabilan sistem FPV di lingkungan laut.

The transition to renewable energy is being accelerated by technologies such as Floating Photovoltaic (FPV), which uses solar panels on floats on the surface of the water. Although innovative, FPVs face stability and durability challenges due to the influence of wind, waves, and ocean currents. This study analyzes the effect of variations in the number of mooring lines and wave direction on hydrodynamic response in FPV. Using a catenary mooring system consisting of anchors, mooring ropes, buoys, and connectors, the study evaluates various configurations to find the optimal solution that ensures the best stability. Numerical simulations based on the Boundary Element Method (BEM) are used to study the dynamic response of FPV to various environmental conditions, focusing on six degrees of freedom of movement: Surge, Sway, and Yaw. The results show that mooring configuration Case 3 consistently delivers the best damping performance for surge, sway, and yaw motions under various wave conditions. This finding reinforces the importance of mooring system design in enhancing the operational stability of FPV platforms in offshore environments.
