Estimation of extreme hydrodynamic environments of Puti Island wind farm in Bohai Sea

In order to manifest the extreme hydrodynamic environments for Puti Island wind farm in Bohai Sea, flow and wave climates in the area induced by cold waves are investigated. According to the historical meteorology statistics and taking the global climate change into account, three typical paths (NNE, ENE and NNW) with four high wind speeds for cold waves in Bohai Sea are presumed. After calibrated with field data, the Princeton Ocean Model (POM) and the third-generation wave model, SWAN, are employed to delineate possible extreme hydrodynamic conditions in the area of Puti Island wind farm. The dependence of the extreme current and water wave parameters to the wind speed and wind direction is investigated. The distribution of the extreme current and water wave parameters in the wind farm is discussed.
