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.
Claims30
A system, comprising:
- a stab body with a longitudinal axis;
- at least one inlet/outlet;
- a coupler body positioned around the stab body, the coupler body being adapted to rotate relative to the stab body while at least the stab body is being moved in a direction of the longitudinal axis;
- at least one coupling element positioned on the coupler body;
- and
- at least one coiled tube positioned around the stab body, the at least one coiled tube being in communication with the at least one coupling element and the at least one inlet/outlet.
A system, comprising:
- a stab body with a longitudinal axis;
- a coupler body positioned around the stab body and having at least one line extending therethrough, the coupler body being adapted to rotate relative to the stab body while at least the stab body is being moved in a direction of the longitudinal axis;
- at least one coupling element positioned on the coupler body and adapted to communicatively connect the at least one line extending through the coupler body to a corresponding at least one line of a first subsea component;
- and
- at least one coiled tube positioned around the stab body, the at least one coiled tube being in communication with the at least one coupling element, wherein the at least one coiled tube is adapted to flex in response to rotation of the coupler body with respect to the stab body.
A method, comprising:
- lowering at least a stab body relative to a first subsea component, wherein a coupler body is positioned around the stab body;
- allowing the coupler body to rotate relative to the stab body while the stab body is lowered relative to the first subsea component;
- flexing at least one coiled tube positioned around the stab body in response to rotation of the coupler body;
- and
- communicatively connecting at least one line extending through the coupler body to a corresponding at least one line of the first subsea component via at least one coupling element positioned on the coupler body, wherein the at least one coiled tube is in communication with the at least one coupling element.
A system, comprising:
- a production stab sub with a longitudinal axis;
- at least one inlet/outlet;
- a rotatable sub positioned around the production stab sub, the rotatable sub being adapted to rotate relative to the production stab sub while at least the production stab sub is being moved in a direction of the longitudinal axis;
- at least one coupling positioned on the rotatable sub;
- and
- at least one coiled tubing positioned around the production stab sub, the at least one coiled tubing being in communication with the at least one coupling and the at least one inlet/outlet.
