NUMERICAL SIMULATION ON HYDRODYNAMIC MOTION RESPONSE FOR FLOATING HYBRID POWER GENERATION SYSTEM IN WAVES

Abstract

This study presents hydrodynamic motion responses of 10MW class floating wave-offshore wind hybrid power generation system and other presented floating offshore wind turbine platforms in waves. A semi-submersible platform has some characteristics that the primary structures are long but very slender. A potential flow based commercial code WADAM from DNV-GL is adopted for numerical simulation. Diffraction & radiation and Morison formula are applied for the primary and secondary structure members in addition, the performance of the motion reducing device which is initially designed in this study is evaluated.
