The "Bilboquet" system consists of a guided float which moves with the force of the waves along a floating anchored column. The float is equipped with racks which actuate the gear generators located in a capsule at the top of the column. The lower part of the column is equipped with a weighted part with vertical hydrodynamic damping to provide three anchor points which contribute to higher vertical stability.

The "Bilboquet" is robust and efficient and can be anchored in various depths. A suitable anchoring system allows the construction of power generation farms. The size of the "Bilboquet" can be adapted to environmental conditions (waves and water depth) and the optimization of energy efficiency which ranges from 1,500 to 3,500 kW, with a demonstrator to 120 kW. The project concerns the development of a reduced power "Bilboquet" whose production and sea trials will validate the R&D to date. In addition, the partners will develop a performance simulation method for a "Bilboquet" farm that could be adapted to other sets of renewable energy devices (e.g. offshore wind turbines).
