ABSTRACT:
A subsea wellhead assembly comprises a subsea wellhead, a spool body assembly, a helix, and a tubular bore protector. The spool body assembly is mounted to the wellhead and has an inside surface defining a vertical bore. The spool body assembly has an upper end, a lower end, and a lateral production fluid outlet port. The helix is formed from a tubular member and is positioned in a lower portion of the spool body assembly. The helix has a generally cylindrical outer surface defining an outer diameter and a generally cylindrical inner surface defining an inner diameter, an upper end and a lower end. The tubular member has an organ pipe-shaped cut in the upper end so that the upper end is generally elliptically shaped and forms a pair of arcuate ramps to orient a tubing hanger. The tubular bore protector body has an upper end, a lower end, and a longitudinal axis. The tubular bore protector is mounted in the spool body assembly with the upper end of the tubular bore protector body being positioned adjacent to the upper end of the spool body assembly. The lower end of the tubular bore protector body is positioned adjacent to the lower end of the spool body assembly. The tubular bore protector body extends inside of the helix, to protect the vertical bore through the spool body assembly and the helix from mechanical damage while the well is being completed.
