3 m deep basin with 12 m deep central pit. 3D wave generation, Internal steady current circulation and wind loading

Description of facility:

DHI’s Offshore Wave Basin is 20 m long and 30 m wide with an overall depth of 3 m and a 12 m pit.

Waves

Short-crested (3D) waves and swell are generated by 60 individually controlled flaps. A parabolic wave absorber located opposite the wavemakers minimizes reflections. Practically any wave spectrum and combination of wave spectra may be generated.

Current

Current is generated in the basin using a technique of entrainment. Water is pumped through high-pressure nozzles, located in a rack in front of the wave generators..

Wind

Wind Load on vessels or structures can be simulated by computer-controlled wind fans.
