Subsea tubing hanger installation and orientation detection process
The patent US12037866B2 outlines a process and system for the installation of a production tubing hanger in a subsea wellhead, specifically within a subsea template. The process involves several key steps: running the tubing hanger and its associated tool through a riser, utilizing a sensor to detect the hanger's orientation relative to the subsea template, adjusting this orientation as necessary, and finally installing the tubing hanger. The claims detail the use of a sensor system that includes a complementary pair of elements, with one element positioned on a riser orientation spool or blowout preventer and the other on the tubing hanger or its running tool. This sensor system can include inductive sensors and is designed to provide positive confirmation of correct orientation before the riser and blowout preventer are removed.
Additionally, the patent describes a system for sensing the alignment of the tubing hanger around a vertical well axis in relation to the subsea template. This system comprises a sensor pair that communicates with a display apparatus on the surface, allowing for real-time confirmation of the tubing hanger's alignment. The claims also specify that the sensor signals can be transmitted wirelessly or through a line up the riser to surface monitoring equipment. Furthermore, the orientation of the wellhead is noted to influence the positioning of a subsea Christmas tree, which is integral to the overall subsea installation process.
