Abstract
A method of connecting a tubing hanger mounted in a subsea wellhead to equipment which is external to the tubing hanger. The method includes securing the tubing hanger to an end of a drill string using a tubing hanger running tool assembly, lowering the drill string from a drilling rig so as to land the tubing hanger on or in the wellhead, running an umbilical from the sea surface to the wellhead, and connecting the umbilical to at least one conduit in the tubing hanger via the tubing hanger running tool assembly. The umbilical is unconnected to the drill string other than via the tubing hanger running tool assembly.
