Abstract (en)
The invention relates to a subsea storage tank (1) comprising a frame (2) and at least one container (3) for storing a liquid mounted in the frame (2), wherein the container (3) has a flexible wall, preferably a bellows (11A, 11B), comprising at least two liquid tight layers (20, 21, 22) and a space (25) between the layers (20, 21, 22). The space (25) is in liquid communication with a passive negative pressure generator (30) that is configured to maintain, at least during storage of a liquid in the container when the container is submerged, the pressure in the liquid in the space (25) below the pressure in the liquid in the container (3).
