Wave and Wind Analyses at a Site of Floating Type Wind Farm

The design wave and wind at a target site of floating type wind farm were estimated by using wind and wave reanalysis data in the North Pacific. The wave analysis database was made from WAM's output calculated by using NCEP wind data. Since the wind data of NCEP and ERA-40 showed the differnce in magnitute due to the resolution, the proper correction coefficients should be required to transform the re-analysis wind data to a target grid point data. Hourly wave predictions were carried out for one year and it was found through comparison with the observed data that those predicted waves were valid. In addition, a statistical method was proposed to estimate a short term return wave height and wind speed by using hourly predicted or measured data.
