Patent ID: 8702460

Claim:
A method for storing and conveying fluids, said method comprising: (a) providing: a non-rigid, water-impermeable device with an elongate shape having a first end, a second end and having a generally planar and streamlined shape in plan view; the first end comprising a first attachment device; the second end comprising a second attachment device; a plurality of ports for intake and exhaust of fluids; at least one of the plurality of ports comprising a valve for the user to adjust buoyancy of the device; at least a portion of the device containing a fluid of lower density than a fluid through which said device is transported; one or more valves in two-way communication with at least a portion of an interior volume of the device and an outside environment; a transmitter for conveying information related to a geographic position of the device; at least a portion of an internal surface area of the device being comprised of a flexible and tear resistant material; a mooring device; an anchored member having a first end, a second end, and a longitudinal length; and a translatable device disposed on the longitudinal length of the anchored member; (b) securing the first attachment device of the first end to the mooring device; (c) securing the second attachment device of the second end to the translatable device disposed on the longitudinal length of the anchored member; (d) lowering the translatable device to a submerged position; (e) positioning the non-rigid, water-impermeable device in a substantially vertical position; (f) filtering said fluid of lower density prior to emptying the device; and (g) rapidly emptying the device of fluids through at least one of said plurality of ports.
