Floating photovoltaic (FPV) systems are a promising offshore renewable energy solution, but their performance depends on accurately predicting hydroelastic responses under wave loading. This study investigates the dynamic behavior of an FPV island through laboratory experiments and numerical modeling. A scaled FPV model was tested at the ITB Wave Laboratory, with Inertial Motion Units (IMUs) measuring acceleration, angular velocity, and pitch. The numerical model was developed in OrcaFlex using the Discrete Modular Beam (DMB) method, with hydrodynamic data obtained from OrcaWave. Baseline comparisons showed large discrepancies between experiment and simulation, particularly in acceleration responses. Through iterative tuning of equivalent beam stiffness, drag coefficients, and structural damping, the numerical model was significantly improved. The final calibrated parameters reduced errors and provided validated input for FPV hydroelastic simulations. This study highlights the DMB method as an efficient tool for FPV analysis, bridging physical and numerical approaches.
