Abstract: A subsea fluid storage system comprising a soft bladder disposed within a pressure balanced reservoir, a rotatable piston, and a piston rotator which rotates and twists the rotatable piston as it travels along a predetermined axis within the pressure balanced reservoir, predictably and repeatabley collapses the soft bladder when the rotating piston cooperatively travels about the piston rotator, twisting the soft bladder as the rotating piston moves along the predetermined axis, collapsing the bladder inward and thereby emptying the bladder of fluid within the bladder. The piston's rotation pulls the soft bladder away from the pressure balanced reservoir's interior, thereby preventing the bladder's binding or pinching the pressure balanced reservoir's interior. In configurations, fluid is allowed to enter the pressure balanced reservoir via a valve until a balance is achieved between an interior and an exterior of the pressure balanced reservoir.

Abstract: A subsea fluid distributor comprises a support framework removably mountable and hydraulically connectable to a subsea structure intermediate the subsea structure and an incoming flying lead's terminator; a plate attached to an upper section of the support framework; a fixed bucket and a valve attached to the support framework; a lower framework attached to a lower portion of the support framework; a first hydraulic tube, in fluid communication with the valve, attached to the lower framework; a flying lead junction plate support framework attached to the lower portion of the support framework; a second hydraulic tube, in fluid communication with various subsea equipment, disposed at least partially within the flying lead junction plate support framework; a first remotely operated vehicle (ROV) torque bucket attached to an upper portion of the flying lead junction plate support framework; and a second ROV torque bucket attached to the upper section of the support framework.

Abstract: 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.
