Abstract: A tensioner assembly for applying tension to a tubular member, such as a riser, can include an upper latch connected to the tubular member, a platform with a bore, and a plurality of lower latch segments, each having a base that is pivotally connected to the platform. After applying tension to the tubular member, the segments pivot inward to form an annular lower latch ring having an inner diameter less than an outer diameter of the upper latch. The assembly can include a locking mechanism that prevents axial movement of the upper latch, relative to the lower latch ring, after engagement. The upper latch can self-center on the lower latch as it is moved into the latching position.

Abstract: A self-inserting seal assembly that sets a seal at a well component to allow for pressure testing of the well component. The seal assembly can be landed on a well component with an ROV. A seal is located on the lower portion of a lower body in the assembly. A set of outer dogs lock with a grooved mating profile formed on the well component to lock the outer housing to provide a reaction point for setting the seal, which may require several thousand pounds of force. A set of inner dogs lock with a grooved mating profile formed on the inner diameter of the outer housing. This locks the lower body to the outer housing to ensure the seal remains set in place. After the well component is pressure tested, the seal assembly can be unlocked and retrieved from the well via an ROV.

Abstract: A seal assembly includes a tubular member having a longitudinal axis and a tubular member seal profile. A metal seal ring having a proximal base and a distal end has a seal ring seal profile between the proximal base and distal end that contacts the tubular member seal profile. A distal annular recess is in one of the seal profiles, the distal annular recess being spaced axially from the distal end of the seal ring, defining a seal surface between the distal end of the seal ring and the distal annular recess that engages a seal surface of the tubular member seal profile. The contacting portions of the seal surfaces form a metal-to-metal seal area. A proximal annular recess in one of the seal profiles is spaced axially from the distal annular recess, defining a support area axially spaced from the metal-to-metal seal area.

Abstract: A tieback connector connects a tieback conduit from an offshore platform to a subsea wellhead assembly. The tieback connector has a mandrel that is connected to a string of tieback conduit and a sleeve and load ring that are carried by the mandrel. The load ring is radially expansible and has a conical portion with internal threads. The load ring has an external grooved profile that engages an internal grooved profile in the subsea assembly. The mandrel is rotatable relative to the sleeve while in its lower position, causing the load ring to further expand outward into engagement with the internal profile. A locking member is carried below the load ring on an exterior cam surface of the mandrel. The cam surface moves the locking member outward when the mandrel moves downward into engagement with an internal profile in the subsea assembly.

Abstract: A wellhead connector for connecting a riser or production tree to a wellhead of a subsea well utilizes a singular annular piston to lock the connector onto the wellhead. The wellhead connector includes a housing that contains dogs for engagement with the exterior of the wellhead housing. A cam ring is also included, which has an inner side for engaging the dogs and moving them inward into a locked position with the wellhead housing. The cam ring is of a reduced proportion relative to prior art. As such, the cam ring outer side is dimensioned to contact the inner side of the connector housing under load. Connecting rods connect the piston to the cam rings. As the piston moves downward, the cam ring also moves downward, forcing the dogs inward into a locked position. As the piston moves upward, the cam ring also moves upward, thereby unlocking the connector. A secondary annular piston is also provided to guarantee unlocking.At preload, a profile on the lower portion of the connector body engages a stepped profile on the outer diameter of the wellhead thereby creating a secondary load path for reacting to the applied bending moment.

Abstract: A riser connector uses a box and upset pin connector threadform design having S-shaped load flanks that provide a variable load angles depending on the radial position along the engaged teeth. This design promotes a load path that changes with position along the axial length of the engaged thread, as well as increasing or decreasing external loads on the connector. The connector also varies radial distention of the pin from the box in a manner that is different from one thread to the next. The threadform uses a combination of thread cuts that vary in shape, pitch, and/or thread cone angle to provide load and stab flanks, as well as a load path, that vary from one axial end of the engaged thread to the other.

Abstract: A tendon or riser connector has a separate lock-down device that overrides the connector's ability to unlock if the riser or tendon goes slack. The locking device has blocks that are radially actuated through a hole in a receptacle to engage a profile in the connector. When the blocks are pushed in, they prevent the connector from moving downward, and thus prevent any unlocking of the connector. The blocks are secured with pivotable gates that engage and retain the blocks in both positions.

Abstract: A riser tensioner for an offshore floating platform has a frame stationarily mounted to the upper portion of the riser. Pistons and cylinders are spaced circumferentially around the riser and connected between the frame and the floating platform. A tubular guide member is mounted to the floating platform for movement in unison in response to waves and currents. The riser extends through the guide member. A guide roller support is mounted to and extends downward from the frame around the guide member. At least one set of guide rollers is mounted to the guide roller support in rolling engagement with the guide member as the guide member moves in unison with the platform.

Abstract: 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.
