Abstract

Penelitian ini menganalisis kekuatan dan respon gerakan struktur pada New Floating Storage and Offloading (FSO) Conversion yang terhubung melalui sistem Single Point Mooring (SPM) tipe CALM (Catenary Anchored Leg Mooring). FSO berfungsi sebagai fasilitas apung untuk penyimpanan dan transfer hidrokarbon dari fasilitas lepas pantai ke kapal tanker. Untuk memastikan kestabilan dan keamanan operasi, diperlukan evaluasi menyeluruh terhadap sistem tambat, khususnya pada anchor chain yang mengalami beban siklik akibat pergerakan enam derajat kebebasan dari struktur apung. Analisis dilakukan menggunakan metode elemen hingga (Finite Element Method) untuk mengevaluasi tegangan maksimum dan deformasi yang terjadi pada rantai jangkar baik sebelum maupun setelah konversi FSO. Simulasi dilakukan dalam kondisi lingkungan yang ditetapkan, termasuk beban gelombang, angin, dan arus. Respon gerakan FSO dan SPM dianalisis melalui pendekatan ranah waktu (time domain), dengan mempertimbangkan Response Amplitude Operator (RAO) dan Load Case berdasarkan kondisi operasional dan ekstrem. Hasil penelitian memberikan informasi teknis terkait performa struktur dan sistem mooring, serta menjadi acuan untuk menentukan batas operasional yang aman sesuai standar internasional (API RP 2SK dan OCIMF). Penelitian ini diharapkan menjadi referensi dalam mendesain dan mengevaluasi sistem mooring FSO agar tetap handal dalam berbagai kondisi lingkungan.

This study analyzes the structural strength and motion response of a New Floating Storage and Offloading (FSO) Conversion, which is moored using a Single Point Mooring (SPM) system of the CALM (Catenary Anchored Leg Mooring) type. The FSO serves as a floating facility for hydrocarbon storage and offloading from Offshore production to shuttle tankers. To ensure operational safety and stability, a comprehensive assessment of the mooring system is required, particularly focusing on the anchor chains subjected to cyclic loads due to six degrees of freedom motion. The analysis is conducted using the Finite Element Method (FEM) to evaluate maximum Stress and deformation on the anchor chain, both before and after the FSO Conversion. Simulations are carried out under defined environmental conditions, including wave, wind, and current loads. The motion response of the FSO and SPM system is analyzed in the time domain, considering the Response Amplitude Operator (RAO) and various load cases under operational and extreme sea states. The results provide technical insights into the structural behavior and mooring performance, serving as a reference for determining safe operational limits in accordance with international standards (API RP 2SK and OCIMF). This research aims to support the design and evaluation of mooring systems for FSO units to ensure long-term reliability under varying environmental conditions.
