Abstract
FSO (Floating Storage and Offloading) merupakan salah satu jenis struktur bangunan lepas pantai terapung yang fungsinya sebagai penyimpanan sementara hidrokarbon sebelum disalurkan ke kapal tanker untuk dibawa ke fasilitas produksi di darat. Komponen penting yang digunakan sebagai penunjang operasi FSO yaitu sistem tambat (mooring system) dan riser. Sistem tambat digunakan untuk membatasi gerakan FSO dari beban lingkungan yang mengenainya. Sedangkan riser berfungsi untuk mengangkut hidrokarbon dari sumur untuk dibawa ke FSO. Riser yang sifatnya fleksibel dan memiliki kekakuan yang rendah dinamakan flexible riser. Dalam penelitian ini dilakukan analisis terhadap tension flexible riser dengan variasi konfigurasi mooring system. Variasi tersebut terdiri dari spread mooring, conventional buoy mooring (4 buoy), dan 2 variasi lainnya merupakan kombinasi antara spread mooring dan conventional buoy mooring. Berdasarkan analisis yang dilakukan dalam tugas akhir ini mooring system dengan konfigurasi 4 buoy mengakibatkan tension flexible riser paling besar yaitu 346 kN sedangkan tension paling kecil terjadi pada flexible riser dengan konfigurasi spread mooring yaitu sebesar 55 kN. FSO dengan konfigurasi 4 buoy (conventional buoy mooring) memiliki offset paling besar dan konfigurasi spread mooring memiliki offset paling kecil. Riser dengan tipe lazy wave memiliki tension lebih kecil daripada tipe free hanging dimana selisihnya 4 – 58%.

FSO (Floating Storage and Offloading) is a floating structure that function as hydrocarbons temporary storage from wells before distributed to tankers and carried to production facilities on shore. The important components used as supporting FSO operations are mooring systems and riser. Mooring systems used to limiting FSO movement due to environmental loads. Riser was carried out hydrocarbons from well to FSO. This study objectives is analysis effect of mooring system configurations to flexible riser tension. These variations consist of spread mooring, conventional buoy mooring (4 buoy), 2 other variations are combination of spread mooring and conventional buoy mooring. This analysis performs that mooring system with 4 buoys have largest flexible riser tension that is 346 kN while spread mooring have smallest flexible riser tension that is 55 kN. FSO with conventional buoy mooring configuration has largest offset and spread mooring configuration has smallest offset. Lazy wave type has smaller riser tension than free hanging type, the difference is 4 – 58%.
