NOVELTY - The installation has a set of bells (200) connected by a connection structure (300), where each bell contains air that is compressed due to the continuous movement of a swell. A storage tank (400) stores and supplies the compressed air to generators (500), where the storage tank is connected to a pressure release valve. A ballasting tank (600) is filled with water for permitting partial or total immersion of the installation during a storm. The ballasting tank is provided with a solenoid valve and a sump pump, and a control unit controls the operation of the valve and the pump.    USE - Used for producing energy from the movement of a swell (claimed).    ADVANTAGE - The ballasting tank is filled with water for allowing partial or total immersion of the maritime installation during a storm, and so the installation is less stressed and consequently dimensioned at the time of the storm. The maritime installation therefore provides resistance against storms. The ballasting tank adjusts the stability of the ballast so as to ensure the rise of the installation at the sea surface after its immersion, thus avoiding a destruction of the installation by the storm. The arrangement of the storage tank, ballasting tank, generators and bell protects the internal wall of the installation. The design of the bell avoids the generation of water hammer during the upward movement of the swell. The control unit controls the operation of the solenoid valve and the pump, thus modifying the buoyancy and optimizing the energy production of the installation besides enabling the installation to adapt to meteorological conditions in real time. The pressure release valve connected to the storage tank limits the internal pressure in the storage tank when the compressed air is not absorbed by the generators. The operation of the generators is therefore interrupted when the output of the bell is insufficient.
