  • the mooring facility is able to rise and fall with tidal changes and secured so as to remain substantially a constant distance from the shoreline during those tidal changes.
  • the floating structure is retained at a predetermined level relative to the water level in a manner similar to that of a diving bell wherein an air vent closed by an air release valve located above the predetermined level is opened to allow the ingress of water through water entry and release ports until the structure settles into the water and the predetermined flotation level is achieved.
  • Another mode of controlling the flotation of the structure could be to provide a sealed structure and pump water into or out of the structure to vary its buoyancy between an operating position and a submerged position.
  • the floating structure can be sunk by opening a buoyancy air release valve so that the structure fills with water and sinks below the surface.
  • the depth to which the structure sinks can be controlled by providing a bottom stop which contacts the sea, lake or river bed to hold the structure a predetermined distance above that bed.

Abstract

L'invention concerne un ponton ou une marina (14) submersible, pouvant être immergés, afin de les préserver contre des conditions environnementales hostiles, et ramenés à un état flottant lorsqu'on le désire. Des chambres de flottabilité gonflables peuvent être sélectivement ouvertes, afin de se remplir d'eau ou de se gonfler, ce qui augmente leur flottabilité. La structure (14) peut être maintenue horizontale lorsqu'on l'immerge ou lorsqu'on la relève, par commande de la position et de la vitesse de gonflage/dégonflage. Le système de commande comprend des soupapes de commande de gaz, destinées être actionnées lorsqu'on applique un angle d'inclinaison prédéterminé à la structure (14), afin de gonfler ou dégonfler certaines chambres discrètes, ce qui permet de maintenir le niveau de la structure pendant l'immersion ou le flottement de ladite structure (14).
