Systems and methods for coupling subsea tubular members together are provided. An apparatus may be used to properly orient and/or provide communication between a first subsea tubular member that is being landed on a second subsea tubular member. An apparatus for coupling subsea tubular members may include an alignment sub and a corresponding alignment member. The alignment sub includes: a generally cylindrical body having one or more fluid, electric, or fiber optic lines extending therethrough, one or more couplings coupled to at least one end of the alignment sub, and an orientation profile disposed on a surface of the alignment sub. The alignment member has a profile designed to interface with the orientation profile of the alignment sub. One of the alignment sub and the alignment member remains stationary while the other rotates relative to the stationary structure.

Systems and methods for landing a tubing hanger in a wellhead and then orienting a tree (or spool, or flowline connection body) relative to the tubing hanger while landing the tree on the wellhead are provided. This alignment is accomplished without the use of either a tubing spool or a BOP stack with an orientation pin. The tubing hanger alignment devices may be used to orientate the tree as the tree is landed so that the couplings and stabs between the tree and the tubing hanger line up with each other just at the moment of landing.

Tubing hanger alignment device

A subsea wellhead assembly having an arrangement of primary well barriers provided in equipment that is located within the well and/or the wellhead housing is provided. The subsea wellhead assembly may include a tubing hanger positioned in or below a wellhead housing coupled to a subsea well, a tree cap fluidly coupled to the tubing hanger and disposed atop the wellhead housing, and a pair of master production valves configured to be selectively actuated from an open position to a closed position to shut in the subsea well, each of the pair of master production valves located within or below the wellhead housing.

A high capacity universal connector for use in connecting tubular members and a method for sealing the tubular members is provided. First and second tubular members are provided which each have ends that are brought into face-to-face engagement by a connector. A metal sealing element seals against conical surfaces at the ends of the first and second tubular members and enables the entire surface of the end of one tubular member to be bought into engagement with the surface of the end of the other tubular member so as to improve the bending and compression capacity of the assembly comprising the tubular members and the metal sealing element. A metal sealing ring for use in this assembly is also provided, along with a gasket retention assembly.

A subsea wellhead assembly having an arrangement of primary well barriers provided in equipment that is located within the well and/or the wellhead housing is provided. All of the well barriers may be located within the tubing hanger and/or the production tubing string extending into the wellbore. The subsea wellhead assembly also includes a flowline connection body placed atop the wellhead housing and fluidly coupled to the tubing hanger. None of the primary barriers for the well are located in the flowline connection body.

An improved anti-rotation device and connector assembly designed to prevent rotation of a first threaded portion of the connector assembly with respect to a second threaded portion of the connector assembly is provided. The anti-rotation device and connector assembly include features that guide and smooth the transition of the anti-rotation device into a position extending through the first and second threaded portions. The anti-rotation device may extend through a tab/groove interface between the first and second threaded portions, or the anti-rotation device may engage opposing interfacing edges of the first and second threaded portions along the length of the anti-rotation device. Once the anti-rotation device is installed through the first and second threaded portions, the anti-rotation device may prevent rotation of the threaded portions relative to each other.

Systems and methods for control/monitoring of internal equipment in a riser assembly are disclosed. The method includes running a tool through at least a portion of an internal bore of a riser assembly associated with a well, and outputting a control signal from a first wireless communication interface disposed along the internal bore of the riser assembly. The first wireless communication interface is coupled to a communication system on the riser assembly. The method also includes receiving the control signal at a second wireless communication interface disposed on the tool, and actuating at least one equipment component of the tool in response to the second wireless communication interface receiving the control signal.
