Floating wind turbine (FWT) plays a significant role in
producing clean, renewable, and sustainable energy. Structural components of
FWT consist of wind turbine, supporting floating platform and mooring lines,
where the floating platform is subjected to coupled aerodynamic and
hydrodynamic loads in the complex sea environment. Understanding the dynamic
behavior of FWT and validating its corresponding numerical simulation tools
require reliable experimental methods to replicate various environmental
loading conditions and realistic FWT dynamic responses. Conventional coupled
wind-wave experiments have provided insight on FWT’s dynamic behavior. However,
scaling conflicts between the Froude and the Reynolds numbers are inevitable.
Thus, distributed Real-Time Hybrid Simulation is proposed to be applied to FWT
dynamic response evaluation subject both aerodynamic and hydrodynamic loads.
Currently, literature review, numerical modeling of FWT structures and virtual
dRTHS have been carried out. The physical dRTHS experiments is being planned.

| Statistics around the globe confirms the increasing
frequency of more extreme weather leading to natural disasters of all types.
In 2020 alone, the U.S. saw 22 separate billion-dollar weather and climate
disaster events including 7 tropical cyclones and 13 severe storms while the number
was only 3 in 1980.
Global warming will continue and climate change will follow.
Severe winds and storms such as tornadoes, hurricanes, downbursts, and thunder
storms, as well as other natural hazards with higher intensities are causing
more damages to all built environment. Building roofs are vulnerable to wind hazards
due to their inherent deficiencies of manufacturing, installation and
weathering.
