This study presents a simplified methodology designed to enhance efficiency and clarity by minimizing procedural complexity without compromising the accuracy and reliability of outcomes. Marine cable systems face operational challenges due to unresolved dynamic equations and quadratic hydrodynamic drag from environmental factors. The study applied numerical solutions to Mooring systems Dynamics validated against those from ANSYS. The hydrodynamic responses of the FPSO and its mooring system were analyzed. Results indicate that the system experiences dynamic loading, with tension forces in the mooring cable ranging from 188,873.27 N to 397,107.78 N. The mooring sum forces exhibit fluctuations, reaching a minimum of -78,858.34 N and a maximum of -31,710.57 N in the global X direction. The heave direction, forces ranged from -389,218.63 to -186,192.23 N. The study found that application of advanced meshing techniques, sensitivity analysis, and integration of real-time environmental data with advanced nonlinear dynamics, can address time-dependent problems in mooring systems to improved simulation-accuracy. This study contributes to the comprehensive understanding of mooring system dynamics, providing valuable insights into the design, operation, and safety of FPSOs in challenging marine environments.
