A method for detecting and preventing leaks of a double-walled container for the storage of poisonous, caustic, irritant and/or combustible media utilizes a double-walled container with an inner wall and an outer wall. A cavity is formed between the inner wall and the outer wall, a positive pressure is generated in the cavity, and in the event of a leak of the inner wall, a gas is fed to the cavity in order to maintain a positive pressure in the cavity. A container system includes an open-loop/closed-loop control device for the open-loop/closed-loop control of a gas throughflow in a line. The system includes a pressure measuring unit for measuring the pressure in the cavity of the double-walled container.

A versatile container a versatile pipe section comprising a sleeve and a tube inserted into the sleeve, the tube being held in place using a first capping element at a first end, at least one mounting element in a middle portion and a second capping element at a second end. The first and second capping elements are provided with an opening of a diameter corresponding to the diameter of the tube for allowing liquid or gas to flow through the tube. Also, a versatile container comprising a sleeve, at least one liquid or gas holding compartment adapted to be positioned within the sleeve, the at least one compartment being held in place using at least one mounting element. The sleeves are adapted to hold the contents of the tube or the at least one compartment in case of a leak.

Using a subsea fluid storage system 1 comprising a soft bladder (20) disposed within a pressure balanced reservoir (10), a rotatable piston (30) disposed at least partially within the pressure balanced reservoir where a top of the soft bladder is in communication with the rotatable piston, and a piston rotator (50) operative to rotate and twist the rotatable piston as the rotatable piston travels along a predetermined axis within the pressure balanced reservoir, a predictable and repeatable collapse of the soft bladder may be obtained by allowing the rotating piston (30) to cooperatively travel about the piston rotator (50) to twist the soft bladder (20) as the rotating piston moves along the predetermined axis in such a manner as to collapse the bladder inward, thereby emptying the bladder of fluid within the bladder. The rotation of the piston pulls the soft bladder away from an interior of the pressure balanced reservoir, thereby preventing binding or pinching of the bladder with respect to the interior of the pressure balanced reservoir. In configurations, fluid is allowed to enter the pressure balanced reservoir via a valve (54) until a balance is achieved between an interior and an exterior of the pressure balanced reservoir.

According to one or more embodiments disclosed herein is a method of transporting equipment between sea-surface and seafloor by providing a structure with equipment mounted thereon. The equipment may be liquid storage tanks, pumps, compressors, separators, metering systems, energy sources, communication systems, buoyancy tanks, and the like. The structure is used for disposal and installation in a subsea environment by changing the volume of buoyancy material within at least one buoyancy tank.
