Abstract

Indonesia memiliki intensitas cahaya matahari yang stabil sepanjang tahun yang memiliki potensi menjadi sumber energi terbarukan berupa energi surya. Pemanfaatan energi surya berupa pengembangan Pembangkit Listrik Tenaga Surya (PLTS) terapung yang bisa diletakkan di perairan seperti danau, pantai dan laut. Tugas akhir ini menganalisis pengaruh bentuk layout multibody floating photovoltaic terhadap respon dinamis dan kekuatan tali tambat pada kondisi Ultimate Limit State dan Accidental Limit State. Penelitian diawali menentukan lokasi penempatan struktur dan analisis kondisi lingkungan. Selanjutnya pemodelan struktur FPV dengan tiga variasi bentuk pontoon untuk dicari bentuk yang memiliki respon gerak paling kecil. Analisis hidrodinamika dilakukan pada kondisi free floating untuk mengetahui respon gerak masing-masing FPV. Hasil RAO struktur yang paling kecil yang digunakan untuk analisis selanjutnya yaitu analisis dinamis dengan dua layout kondisi ULS dan ALS untuk mendapatkan nilai tension dan offset. Hasil penelitian menujukkan lokasi dan kondisi lingkungan yang ditempati struktur yang terletak pada koordinat 5.44'55 106.3 tinggi gelombang 0,2 m dengan periode 4,25 s. Kecepatan angin 15 m/s. Kecepatan arus 0,138 m/s. kedalaman 30 meter. nilai maksimum RAO struktur terpilih surge 0,927 m/m, sway 0,959 m/m, dan heave 1 m/m, roll 17,561 deg/m, pitch 10,334 deg/m, dan yaw 2,983 deg/m. Pada kondisi ULS, tension pada layout 2 lebih besar daripada tension pada layout 1. Tension terbesar terjadi pada layout 2 dengan konfigurasi crossed catenary mooring dengan arah pembebanan 90 sebesar 413,16 kN. Pada kondisi ALS, tension pada layout 2 lebih besar daripada tension pada layout 1. Tension terbesar terjadi pada layout 2 dengan konfigurasi crossed catenary mooring dengan arah pembebanan 90 sebesar 583,58 kN. Kedua layout mengalami peningkatan offset pada kondisi ALS dengan nilai terbesar pada layout 1 arah 90° sebesar 2,41 m untuk FPV1, 1,63 untuk FPV2, 1,88 m untuk FPV3, 2,48 m untuk FPV4, 1,55 m untuk FPV5, 1,80 m untuk FPV6.

Indonesia has a stable intensity of sunlight throughout the year which has the potential to become a source of renewable energy in the form of solar energy. The use of solar energy is in the form of the development of floating Solar Power Plants (PLTS) that can be placed in waters such as lakes, beaches and seas. This final project analyzes the influence of the shape of the multibody floating photovoltaic layout on dynamic response and mooring rope strength under the conditions of Ultimate Limit State and Accidental Limit State. The research began to determine the location of the placement of the structure and analyze the environmental conditions. Furthermore, FPV structure modeling with three variations of pontoon shapes to find the shape that has the least motion response. Hydrodynamic analysis was carried out in free floating conditions to determine the motion response of each FPV. The results of the smallest structure RAO were used for the next analysis, namely dynamic analysis with two layouts of ULS and ALS conditions to obtain tension and offset values. The results of the study showed the location and environmental conditions occupied by the structure located at coordinates 5.44'55 106.3 with a wave height of 0.2 m with a period of 4.25 s. Wind speed 15 m/s. The current speed is 0.138 m/s. 30 meters deep. The maximum RAO value of the selected structure surge 0.927 m/m, sway 0.959 m/m, and heave 1 m/m, roll 17.561 deg/m, pitch 10.334 deg/m, and yaw 2.983 deg/m. In the ULS condition, the tension in layout 2 is greater than the tension in layout 1. The largest tension occurred in layout 2 with a crossed catenary mooring configuration with a loading direction of 90 of 413.16 kN. In the condition of ALS, the tension in layout 2 is greater than the tension in layout 1. The largest tension occurred in layout 2 with a crossed catenary mooring configuration with a loading direction of 90 of 583.58 kN. Both layouts experienced an increase in offset in the ALS condition with the largest values in the 1-way 90° layout of 2.41 m for FPV1, 1.63 for FPV2, 1.88 m for FPV3, 2.48 m for FPV4, 1.55 m for FPV5, 1.80 m for FPV6.
