The present invention relates to a method for lifting a structure intended for sea-fish farming in deep waters, and to the corresponding structure. The method consists generally in displacing, by draining ballast tanks 4, 4', the centre of pressure P so that this is not (or does not remain) vertical with the centre of gravity G, the structure still being in contact with the bottom 10. This results in a tilting moment which "detaches" the structure from the bottom and facilitates its removal. The ballast tanks form an integral part of the structure. <IMAGE> |
