The FloWave Ocean Energy Research Facility is a circular combined current and wave test tank optimised for modelling at scales between approximately 1:30 and 1:10. The facility employs a unique configuration with 168 wavemakers and 28 flow-drives installed around the circumference of the 25m diameter, 2m deep, circular basin. The tank therefore has no preferential orientation, allowing independent control of both the wave and current direction through all 360 degrees, i.e. more complex and ocean-like conditions than any other tank in the world. This, combined with a large test area, provides the ability to more effectively and practically test arrays of marine energy devices, as well as single devices and a range of other ocean technologies. The facility is equipped with an extensive instrumentation suite for measuring waves, current, turbulence, static and hydrodynamic forces and also includes the latest above and below water 3D video motion capture (Qualisys).
