Abstract (en)
[origin: FR2913228A1] The device (1) has an anchoring unit for anchoring a base in a reversible manner on a bottom wall (6) of the sea by maintaining a large orifice at a distance from the wall. A circular cutting unit is integrated to the base and displaced in the large orifice of the base for cutting a small circular orifice below the large orifice, when a stopper is in a closure position and the base is anchored on the wall. The cutting unit is disengaged from the large orifice for opening the small circular orifice when the stopper is in an open position. Independent claims are also included for the following: (1) a method for installing and anchoring a base on a bottom wall of the sea and for cutting a small orifice in the wall (2) a method for recovering a viscous fluid contained in a tank of a damaged or wrecked ship.
