Ancored Arrays

Anchored groups of Subwave units will be deployed in coastal waters where water depths permit anchoring but is deeper than the wave base. A cable will transmit power to the consumer. The seabed conditions are irrelevant. The same goes for tides. Strong current, on the other hand, will cause problems and should be avoided.

The turbines shall be located at a depth of at least half the prevailing wavelength in the sea area where it is deployed. Here, the turbines will operate in an almost stagnant body of water and will be shielded from the impact on the surface. There will be little sunlight at such depths. This reduces the problem of biological fouling.

The water movement down in the depths is illustrated below.

Explanation: The red circles are the present positions of massless particles, moving with the flow velocity. The light-blue line gives the path of these particles, and the light-blue circles the particle position after each wave period. The white dots are fluid particles, also followed in time.
