Abstract: A pipe (14) extending between a surface end (20) and a bottom end (22) thereof, and defining an internal passage (24) ending at the bottom end (22) and at the surface end (20). A dynamic closing member (30) at the bottom end (22), which opens above a threshold pressure applied from the exterior towards the interior of the pipe (14), and closing below the threshold pressure. The threshold pressure is defined as a function of at least one parameter representing the heaving of the pipe under the effect of variation in height of the water in which the pipe extends.
