FloatLab
DTU Wind and DHI jointly operate the FloatLab test facility in DHI's deep-water basin in Hørsholm. FloatLab combines expertise in wind engineering and hydrodynamics in a single test environment, enabling testing of scaled floating wind turbines under combined wind and wave conditions.
About the Lab
The facility features one of the world's largest open-jet wind generators for floating wind testing in turbulent wind. The facility has been used to test a scale model of a 22 MW floating wind turbine and its floating foundation under realistic wind and wave conditions.
The test turbine and combined wind-wave environment can be used to evaluate a variety of floating foundations, mooring and turbine control systems, engineering and numerical models, and marine operations such as installation.
Key Capabilities
- Ocean wave basin measuring 30 m × 20 m
- 5x5 m open-jet wind generator with 25 individually controlled fans
- 60 wave paddles enabling multidirectional wave conditions
- Wind speeds up to 5 m/s (equivalent to 42 m/s at 1:70 scale)
- Turbulence and wind shear generation
- Test turbine with 4m rotor – 1:70 scaled IEA WIND 22 MW turbine
- Options for software in the loop for hybrid testing
- Integration with digital modelling and digital twin frameworks.
Technical Data
FloatLab combines an open-jet wind generator with a multidirectional wave basin and a comprehensive measurement system. Instrumentation includes a Qualisys motion capture system, accelerometers, wave gauges, hotwire gauges, force measurements, sectional load measurements, and hydrodynamic pressure measurements.
