Abstract
A system for orienting a tubing hanger in a wellhead in subsea oil well equipment. The system comprises a tubing hanger having an extendable orientation pin that interfaces with a helical surface inside the high pressure housing of the wellhead, causing the tubing hanger to rotate to a desired rotational position upon the application of upward force to the tubing hanger. The tubing hanger may then be lowered (relanded) and secured, maintaining the desired rotational position.
