Abstract

Energi arus laut merupakan salah satu sumber energi terbarukan yang menjanjikan dan berpotensi besar untuk dikembangkan sebagai solusi pembangkit listrik berkelanjutan. Pemanfaatan teknologi turbin arus laut membutuhkan platform terapung yang stabil untuk memastikan kinerja optimal dan keandalan sistem dalam jangka panjang. Trimaran dan catamaran adalah dua jenis platform yang dapat digunakan untuk mendukung turbin arus laut. Tugas akhir ini bertujuan untuk mengevaluasi performa dua jenis platform terapung, yaitu catamaran dengan satu turbin arus laut berkapasitas 12 kW dan trimaran dengan dua turbin yang masing-masing berkapasitas 6 kW. Simulasi dilakukan menggunakan perangkat lunak StarCCM+ pada variasi kecepatan arus 1–5 m/s untuk menganalisis nilai resistance, respons gerak (surge, sway, heave, dan pitch), serta tegangan mooring dengan jenis catenary pada dua sudut konfigurasi yaitu 15° dan 60°. Hasil simulasi menunjukkan bahwa catamaran memiliki resistance lebih rendah dibandingkan trimaran pada semua kecepatan dan konfigurasi mooring. Namun, dalam aspek stabilitas gerak trimaran menunjukkan respons translasi dan rotasi yang lebih stabil terutama pada arah surge, sway, dan pitch. Selain itu, konfigurasi mooring 60° memberikan performa yang lebih baik dibandingkan konfigurasi 15° yang ditandai dengan berkurangnya total drag dan respons gerak

Ocean current energy is a promising renewable energy source with significant potential to be developed as a sustainable power generation solution. The utilization of ocean current turbines requires a stable floating platform to ensure optimal performance and long-term system reliability. Trimaran and catamaran are two types of platforms that can be used to support ocean current turbines. This final project aims to evaluate the performance of two types of floating platforms, specifically a catamaran with a single 12 kW turbine and a trimaran with two 6 kW turbines. Simulations were conducted using the StarCCM+ software under current velocities ranging from 1 to 5 m/s to analyze resistance, motion responses (surge, sway, heave, and pitch), and mooring tension using catenary-type mooring with two configuration angles, which were 15° and 60°.The simulation results indicate that the catamaran exhibits lower resistance than the trimaran across all current speeds and mooring configurations. However, in terms of motion stability the trimaran shows more stable translational and rotational responses, particularly in the surge, sway, and pitch directions. Additionally, the 60° mooring configuration yields better performance compared to the 15° configuration, as indicated by reduced total drag and motion responses
