Offshore wind industry is forecasted to become a trillion-dollar industry in the next few decades. Significant investments are expected from Asian and American markets. Seismic actions may be a dominant design factor for those regions. With this talk we will go through a number of technical myths and fallacies around the rising offshore wind industry in seismic countries. The talk comprises two parts. First, a general identification of the issues associated with the seismic design/assessment is provided. Then, few applications are demonstrated on the seismic behaviour of typical monopiles offshore wind turbines
