Analysis and Calculation of Extreme Wind Speed and Wave Height for the Design of Marine Engineering

In this paper, the weather and climate conditions are analysed for creating extreme wind speed and wave height over western Huanghai Sea which can be divided into seven subregions. According to different data sets from these subregions, seven correlation formulas are established to calculate annual maximum extreme wind speeds. Extreme wind speeds can be derived for various recurrent periods of each subregion, by means of the Type-I probability distribution of extreme. With the spectral ocean wave model (SOWM) data, the extreme wave heights during the periods can also be derived for the two grid points, which are reasonable compared with the offshore statistical wave heights
