Abstract
Metocean measurement at Fukushima test site was carried out and metocean characteristics were investigated. The effect of met mast tower on the measured wind speed can be mitigated by using the CFD simulation. Furthermore, the corrected wind speed data from the cup anemometer show good agreement with the wind speed measured by Lidar. The prevailing wind direction is NNW in winter and SSW in summer. The spectral significant wave height and period measured by wave buoy show good agreement with the statistical significant wave height and period measured by the wave meter. The prevailing wave direction is easterly all through the year. The current speed and direction measured by ADCP and wave meter show good agreement. The prevailing current direction is southbound cause by local current (Oya-shio)
