Abstract
A subsea storage tank for the storage of bulk fluids is adapted for being set on the sea floor, and is adapted for supplying to local subsea oil and gas production facilities a wide variety of production support fluids. The subsea storage tank includes an inner and outer shell, the shells being adapted so that a barrier fluid can be inserted into and between the shells. An interior barrier separates the interior stored fluid from sea water that is free to enter into the tank, on the opposite side of the barrier, to compensate to the varying volume of stored fluid. An identical tandem barrier is formed nearly identical to the first barrier, and is formed and positioned so that the two barriers act together, and so that the space between them can contain fluid as well, and acts like a bladder.
