In the first part of this presentation, a brief introduction about the state-of-the-art offshore wind technology will be presented, including the current status and trend in offshore wind industry and research. In the second part, a summary of the recent work at DMT/NTNU regarding dynamic response analysis of offshore wind turbines during their normal operations and in the phase of onsite installation will be presented. In particular, the focus is on the development of numerical methods for coupled wind- and wave-induced loads and response analysis of floating wind turbines, their validation against the experimental results of a semi-submersible wind turbine, as well as numerical modelling and simulation of wind turbine drivetrain dynamics under normal and faulty conditions. Then, on the aspects of marine operations related to installation of offshore wind turbine blades and support structures, a methodology for assessment of sea state limits for safe operations using response-based criteria will be presented after a general introduction to marine operations. Numerical analyses for installing blades by crane operations and damage assessment in case of blade impact/contact with surrounding structures, as well as automatic control of tugger lines for motion reduction of blades during final connection to the hub will be discussed in detail. Main conclusions and suggestions for future work.
