摘要

Set of the underwater wellhead and method of training a set of subsea wellhead. This is a set of subsea wellhead (20) which has a tubing hanger (26) located in a coil (22) of tubing hanger (26) and a ring (34) with axial passages (46) located in an upper end of the tubing hanger (26).The set of well head (20) includes a production tree (40) which is based on the coil (22) of the tubing hanger (26). The tubing (32) extends from the axial passages (35) on the ring (34) through axial holes (30) located on a side wall of the tubing hanger (26).When seated, a lower end of the tree production (40) engages an upper surface of the ring (34), making the ring (34) rotate and align their axial passages (35) with the axial passages (46) in the tree output (40). The respective top and bottom surfaces of the tree (40) and ring (34) are strategically ameadas to guide passages (35), (46).
