Two-Body Wave Energy Converter Seabed Stabilization

The patent applies counterweight by using the seabed as a reaction mass to stabilize the floating WEC structure. Tensioned cables connect the floating body to the seabed, creating a counterbalancing system where the seabed mass acts as a stable anchor point. This eliminates the need for a massive onboard reaction body, reducing capital cost while maintaining stability through the cable-tensioned connection to the seabed.

The patent introduces tensioned cables as an intermediary element between the floating WEC body and the seabed. These cables transmit and distribute wave-induced forces, allowing the floating structure to remain stable without requiring a massive reaction body. The cables act as a flexible mediator that enables stability through external seabed anchoring rather than internal mass.

The seabed acts as a counterweight to the low-mass floating WEC body. The tensioned cables create a mechanical connection where the seabed mass provides the stabilizing force, allowing the floating structure to remain stable with minimal onboard mass. This counterbalancing system enables cost-effective deployment without sacrificing stability.

Tensioned cables serve as the intermediary that transfers stabilizing forces from the seabed to the low-mass floating body. This intermediary system allows the lightweight structure to achieve stability externally through the cable-seabed connection, rather than relying on internal mass distribution.

The seabed reaction mass provides passive stabilization through the tensioned cable system, counteracting wave-induced motions without requiring active damping mechanisms. The natural tension and geometry of the cable-seabed system create restorative forces that control motion, eliminating the need for complex active damping systems.

The WEC system utilizes the seabed and cable tensioning system to automatically stabilize itself against wave-induced motions. The passive mechanical system self-regulates motion through the inherent properties of the tensioned cables and seabed anchoring, without requiring external control systems or complex damping mechanisms.

The seabed reaction mass counterbalances the floating WEC structure, distributing wave-induced loads through the tensioned cable system. The counterweight effect reduces peak dynamic loads on the cables by providing a stable reference point, as the seabed anchors the system and prevents excessive displacement that would create high cable tensions.

The tensioned cables act as flexible intermediaries that distribute and absorb wave-induced forces through their tensioning system. The cable geometry and tensioning allow for load distribution across multiple attachment points, reducing peak stresses while maintaining stability through the seabed connection.
