摘要： A hydro-pneumatic tensioner includes a barrel having an inner bore and a pressurized fluid contained within to form at least part of a primary accumulator having a preset volume of gas at a nominal pressure. A piston having a piston rod extending from an aperture in the barrel is slidably carried in the bore of the barrel and is in communication with the pressurized fluid and positioned to increase the fluid pressure when the piston strokes in the direction of the pressurized fluid. A secondary accumulator also has a preset volume of gas at a preselected pressure. A fluid separator maintains functional separation of the fluid volumes of the primary and secondary accumulators when the primary accumulator pressure is less than the preselected secondary accumulator pressure. The fluid separator allows functional combining of the fluid volumes of the primary and secondary accumulators when the primary accumulator pressure equals or is greater than the preselected secondary accumulator pressure.

摘要： A surface assembly that communicates with subsea structures and includes a working deck on a floating structure. The working deck has an aperture extending axially therethrough. A riser extends from a subsea location to the working deck and through the aperture. The surface assembly includes a frame extending circumferentially around the riser so that the frame moves axially with the riser. The assembly also includes a tensioner assembly connected between the working deck and the frame. The tensioner assembly includes a piston slidably carried in a piston chamber, a piston rod extending from the piston and away from the piston chamber, and a shroud enclosing the piston rod. The shroud has a plurality of segments with at least one of the shroud segments being movable in unison with the piston rod.

摘要： A tieback connector connects a riser between a subsea wellhead housing and a floating platform. The tieback connector has a tubular body that stabs into and seals with a casing hanger. A latch member on the tieback connector engages a locking profile to secure the tieback connector to the wellhead housing. A sleeve is slidably carried on the tubular body between a running-in position and a set position. The lower end of the sleeve lands on an upper rim of the casing hanger prior to the seal engaging the seal surface. Continued downward movement of the tubular body relative to the sleeve causes the seal to engage the seal surface and the sleeve to move to the set position. The sleeve has upper end that engages a lower end of the latch member to limit any upward movement of the casing hanger in the wellhead housing.
摘要翻译：连接连接器将海底井口壳体和浮动平台之间的提升管连接起来。连接器连接器具有刺入并与套管悬挂器密封的管状体。连接器连接器上的闩锁构件接合锁定轮廓，以将接头连接器固定到井口壳体。套管可滑动地承载在管状本体上，在入口位置和设定位置之间。在密封件接合密封表面之前，套筒的下端在套管悬挂架的上边缘上着陆。管状体相对于套筒的继续向下运动导致密封件接合密封表面和套筒以移动到设定位置。套筒具有接合闩锁构件的下端的上端，以限制壳体悬挂器在井口壳体中的任何向上运动。

摘要： A tensioner for an offshore structure has inner and outer barrels engaging each other for movement between retracted and extended positions. The barrels are filled with gas pressure. A primary seal is located between the inner and outer barrels at the open end of the inner barrel. An annular lubricant reservoir is mounted to an interior wall surface of the inner barrel at the open end of the inner barrel. A lubricant port extends from the lubricant reservoir through the inner barrel to a high pressure side of the primary seal for dispensing lubricant between the inner and outer barrels. A fill tube leads from the reservoir to the exterior of the inner barrel for replenishing lubricant.
