Abstract

A technique is provided for properly orienting a subsea tree with respect to a tubing hanger landed in a subsea wellhead. An alignment ring is rotationally positioned on the subsea wellhead such that a coarse alignment feature of the alignment ring is at a desired angular orientation with respect to a fine alignment feature on the tubing hanger. The alignment ring is then secured to the subsea wellhead. Subsequently, a subsea tree may be rotationally oriented with respect to the tubing hanger as the subsea tree is landed on the subsea wellhead. As the subsea tree engages the coarse alignment feature, the coarse alignment feature guides the subsea tree into engagement with the fine alignment feature of the tubing hanger to ensure proper rotational orientation as landing of the subsea tree is completed.
