Abstract
The invention relates to an installation having at least one caisson positioned at a given depth in a marine environment, said caisson including a rigid tank in which an oscillating plate moves, said oscillating plate being adapted to oscillate in relation to a vertical axis depending on fluctuations in the height of the water column created by the swell perpendicular to the plate, said tank and plate defining a chamber. The installation is characterized in that the chamber is sealed by a flexible hermetic pouch which is filled with a gas and deforms according to the oscillations of the oscillating plate, the pressure of the gas inside the pouch being adjusted so as to compensate for all or part of the weight of the water column perpendicular to the plate in the absence of swell.
