  • Publication number: 20190264813
    Abstract: Embodiments of the present disclosure include systems and methods with a piston cylinder arrangement comprising an inner barrel positioned within an outer barrel, the inner barrel being linearly moveable along an axis. A primary sealing assembly at an upper end of the outer barrel includes a plurality of seals positioned to block debris from entering an interior chamber. Additionally, an end cap is coupled to the inner barrel and an end cap diameter is greater than an inner barrel outer diameter. Moreover a secondary sealing assembly is arranged between the end cap and the primary sealing assembly and includes a plurality of secondary seals positioned to block debris from entering the interior chamber of the riser tensioner, wherein the secondary sealing assembly reduces a stroke length of the inner barrel when installed above the primary sealing assembly.

  • Patent number: 10174566
    Abstract: Embodiments of the present disclosure include a riser tensioner includes a cylinder barrel, a rod reciprocally carried within the cylinder barrel and having an external end sealingly extending out of a proximal end of the cylinder barrel, and a piston on an interior end of the rod that slides and seals against an inner surface of the cylinder barrel. The tensioner further includes a selectively sealed low pressure chamber in the cylinder barrel between the piston and a distal end of the cylinder barrel and fillable with a low pressure fluid, and a selectively sealed annulus between the rod and the cylinder barrel, the annulus extending between the piston and the proximal end of the cylinder barrel and fillable with an annulus fluid at a pressure higher than the low pressure fluid, thereby urging the piston and rod towards retraction.

  • Patent number: 9816538
    Abstract: A hydraulic cylinder enclosing a cavity, the cylinder containing a thru hole, an inner cylinder surface, and a longitudinal axis, and a piston within the cavity and movable relative to the cylinder in parallel to the longitudinal axis between a first and second positions. The piston includes a rod extending through the thru hole, the piston attached to the rod and in sealed engagement with the inner cylinder surface, and dividing the cavity into low and high pressure cavities, and each of the low and high pressure cavities containing a hydraulic fluid. The hydraulic cylinder further including a flexible bladder within the high pressure cavity containing a gas and preventing the gas from mixing with hydraulic fluid in the high pressure cavity.
