Enhancing Pure Oscillatory Response Motion Performance: Innovative Designs for Semi-Submersible and Catamaran Floating Photovoltaic Systems (FPVs) in Various Sea-State Conditions

A study approach to the novel design of floating photovoltaic systems has been provided using CFD simulation to determine motion characteristics on irregular waves with the JONSW AP spectrum under various water conditions. The simulation included in the frequency domain, shows that the CFPV model exhibits more stable behavior compared to its alternative model. This is due to the findings that the SFPV model has motion excitation associated with its own RAO against the wave energy spectrum at a frequency of 2.13 rad/sec (SS-2). This leads to a significantly dominant difference in motion quality concerning the significant response motion parameter. The quality difference values can be distinguished as heave with a value of 0.26 meters, roll with a value of 4.19°, and pitch with a value of 1.27°.
