Recent Advances in Integrated Response Analsysis of Floating Wind Turbines in a Reliability Perspective
Offshore wind provides an important source of renewable energy. While wind turbines fixed to the seabed in shallow water have already been industrialized, floating wind turbines are still at an early stage of development. The cost of wind power is decreasing fast. Yet, the main challenges, especiall...
