Abstract
Perkembangan teknologi sistem fotovoltaik terapung (Floating merupakan kemajuan signifikan dalam sektor energi terbarukan, khususnya sebagai solusi terhadap tantangan pembebasan lahan. Pergeseran perspektif instalasi berbasis dekat pantai (yang kemudian dapat dipindahkan ke lepas pantai) memberikan area alternatif teknis yang lebih fleksible dan membuka potensi ruang laut yang luas, meskipun harus menghadapi tantangan berupa lingkungan keras yang disebabkan oleh gelombang. Penelitian ini berfokus pada desain inovatif, kinerja seakeeping (olah gerak), dan operabilitas dari berbagai konfigurasi lambung kapal multihull—catamaran, trimaran, quadrimaran, dan pentamaran—yang berfungsi sebagai platform terapung untuk panel surya di lokasi geografis tertentu, seperti wilayah Pulau Gili Ketapang sebagai perwakilan dari pulau terpencil di Indonesia. Dengan menggunakan pendekatan Boundary Element Method (BEM), serangkaian simulasi dilakukan untuk mendapatkan Response Amplitude Operators (RAOs) dari FPV di bawah kondisi spektrum gelombang irregular dalam keadaan initial free-floating state. Untuk menyesuaikan dengan fenomena gelombang irregular, superposisi energi spektrum gelombang dan gaya RAOs gerakan digunakan untuk memperoleh spektrum respons energi struktural. Parameter stokastik kemudian diturunkan dan dikorelasikan pada frekuensigelombang tertentu. Dengan mengintegrasikan data distribusi ketinggiangelombang lokal dari European Centre for Medium-Range Weather Forecasts(ECMWF), hasil dari amplitudo respons gerakan signifikan, ζrs dalam mode heave, roll, dan pitch dievaluasi. Hasil studi menujukkan bahwa penambahan lambungkapal menyebabkan penurunan amplitudo respons signifikan, ζrs di ketiga modegerakan tersebut. Secara keseluruhan, studi ini menyajikan wawasan berharga tentang desain struktur apung dalam evaluasi hidrodinamik FPV serta berkontribusipada upaya global dalam transisi menuju net-zero emissions dan menawarkanalternatif yang menjanjikan untuk mengatasi tantangan akses energi di wilayah terpencil.

The development of floating photovoltaic (FPV) systems represents a significant advancement in renewable energy technology, particularly as a solution to land acquisition challenges. Shifting to near-shore-based installations (later can be moved offshore) provides a flexible technical alternative area and unlocks vast ocean space potential, though facing the harsh environments caused by waves. This research focuses on the innovative design, seakeeping performance and operability of various multihull configurations—catamaran, trimaran, quadrimaran, and pentamaran—serving as floating platforms for solar panels in specific geographic locations, such as the Gili Ketapang region in Indonesia as a representative of a remote island. Using a Boundary Element Method (BEM) model, a series of simulations were conducted to obtain the Response Amplitude Operators (RAOs) of FPV under irregular wave spectrum conditions in the initial free-floating state. To keep up with irregular wave phenomena, the superposition of wave spectral energy and motion RAOs forces are to obtain spectral structural responses.Stochastic parameters are then generated and correlated with a specific wave frequency. By integrating localized wave height distribution data from the European Centre for Medium-Range Weather Forecasts (ECMWF) then the result of significant response amplitude motion in heave, roll and pitch modes is evaluated. It is found that the addition of hulls causes a decrease in the significant amplitude response in all three modes of motion. In summary, this work presents valuable insights into the floater designs and hydrodynamic evaluation of FPV and contributes to the broader effort in the global transition toward net-zero emissions and offers a promising alternative for addressing energy access challenges in isolated regions
