Appl. No.:

17/874196

International Classification:

E21B 33/04
E21B 33/043

Abstract:

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.

International Classification:

E21B 33/04
E21B 33/043

Abstract:

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.

International Classification:

E21B 33/04

Abstract:

Systems and methods for landing a tubing hanger in a wellhead and then orienting a tubular housing (e.g., tree, spool, or flowline connection body) relative to the tubing hanger while landing the tubular housing on the wellhead are provided. The systems may include a tubing hanger alignment device, wherein the tubing hanger alignment device includes one or more hydraulic, electric, or fiber optic lines extending therethrough and one or more couplings disposed on a lower end thereof. The tubing hanger alignment device is configured to couple one or more hydraulic, electric, or fiber optic lines on the tubular housing with one or more hydraulic, electric, or fiber optic couplings on the tubing hanger during landing of the tubular housing onto the wellhead regardless of a relative orientation of the tubing hanger and the tubular housing with respect to the wellhead.
