Anchoring Systems

Definition

Anchoring systems are critical structures used to secure wave energy converters to the seabed, ensuring stability and proper functionality in varying marine conditions. These systems play a vital role in maintaining the position of converters against the forces of waves, currents, and wind, which can otherwise cause displacement or damage. The design and effectiveness of anchoring systems directly influence the performance and longevity of wave energy devices.
