Abstract
A subsea production system that is adapted to be coupled to a subsea wellhead and includes a tubing hanger adapted to be positioned in the wellhead. The tubing hanger has a flow opening extending therethrough and has at least one eccentrically located opening extending through the tubing hanger. In some cases, the tubing hanger is adapted to be not precisely oriented with respect to a fixed reference point when positioned in the wellhead. The system also includes a production tree adapted to be operatively coupled to the tubing hanger, wherein the production tree is oriented relative to the tubing hanger. In other embodiments, the tubing hanger is riot oriented with respect to the wellhead or other fixed reference point.
