Abstract

English

This research discusses the effect of fairlead position on the fatigue damage ratio of the Aoka Mizu Floating Production Storage and Offloading (FPSO) catenary structure during moored conditions. The FPSO is subject to the influence of ocean waves, ocean currents, and wind that can cause significant movement, jeopardize the catenary mooring system, and disrupt the production process. This study utilizes a numerical method based on the Boundary Element Method and uses environmental data from the Masela Block, which includes wave, wind, and current data. Three variations of fairlead position (0.3T, 0.5T, and 0.9T), each referring to the fairlead distance from the laden to the ship's keel, were tested with a rope length of 3100 m and a sea depth of 1000 m. The results showed that a fairlead position of 0.3T resulted in low stress and damage levels, while fairlead positions of 0.5T and 0.9T resulted in higher stress and damage. The fairlead position plays an important role in determining the stability and performance of the FPSO catenary structure. A fairlead position of 0.3T appears to be the most favorable option to reduce the risk of damage and stress to the FPSO Aoka Mizu catenary mooring system during moored conditions.

Bahasa Indonesia

Penelitian ini membahas pengaruh posisi fairlead terhadap rasio kerusakan akibat kelelahan atau fatigue damage ratio pada struktur catenary Floating Production Storage and Offloading (FPSO) Aoka Mizu selama kondisi tertambat. FPSO ini tentunya tunduk pada pengaruh gelombang laut, arus laut, dan angin yang dapat menyebabkan pergerakan yang signifikan, membahayakan sistem tambat catenary, serta mengganggu proses produksi. Penelitian ini menggunakan metode numerik berasis Boundary Element Method serta menggunakan data lingkungan dari Blok Masela, yang mencakup data gelombang, angin, dan arus. Tiga variasi posisi fairlead (0.3T, 0.5T, dan 0.9T) yang masing-masing merujuk pada jarak fairlead dari sarat ke keel kapal, diuji dengan panjang tali 3100 m dan kedalaman laut 1000 m. Hasil penelitian menunjukkan bahwa posisi fairlead 0.3T menghasilkan tegangan dan tingkat kerusakan yang rendah, sementara posisi fairlead 0.5T dan 0.9T menghasilkan tegangan dan kerusakan yang lebih tinggi. Posisi fairlead berperan penting dalam menentukan stabilitas dan kinerja struktur catenary FPSO. Posisi fairlead 0.3T tampaknya menjadi pilihan yang paling menguntungkan untuk mengurangi risiko kerusakan dan tegangan pada sistem tambat catenary FPSO Aoka Mizu selama kondisi tertambat.
