Abstract

L'invention concerne un appareil à stocker de la matière liquide dans de l'eau. L'appareil s'installe dans une rivière, en mer, dans un lac ou analogue, et comprend un réservoir de stockage de matière liquide disposé de manière à occuper une zone prédéterminée dans l'eau. L'appareil comprend un orifice d'admission de matière liquide par lequel passe une matière liquide à stocker (p. ex. eau fraîche, eau de mer, eau résiduaire à purifier, substance chimique liquide, pétrole). Une forme extérieure du réservoir de stockage de matière liquide est modifiée par la pression externe de l'eau lorsque la matière liquide y est stockée en quantité inférieure à la capacité de stockage maximale du réservoir. L'appareil comprend également un moyen de fermeture de l'orifice d'admission de matière liquide du réservoir destiné à fermer de manière étanche le réservoir. L'appareil à stocker de la matière liquide s'installe aisément dans l'eau pour permettre simultanément le stockage et le transport d'une grande quantité de matière liquide et la réduction radicale des coûts de construction, par comparaison avec un appareil de stockage installé sur la terre ferme.
