Abstract:
A subsea wellhead assembly provides a positive indication of landing of a wellhead member and locking of a wellhead member to a wellhead. The subsea wellhead assembly includes at least one positive indicator assembly disposed within a wellhead member, and a communication line extending down a running string from a platform to a running tool disposed in a subsea wellhead. The at least one positive indicator assembly provides confirmation of setting of the wellhead member, and the communication line is in communication with the positive indicator assembly to communicate the confirmation of setting with the platform following setting of the wellhead member.

Claim (Index 10):
A subsea wellhead assembly, comprising:\n a pipe hanger having an actuation sleeve that is axially moveable from an upper to a lower position relative to an axis of the pipe hanger; a running tool for installing the pipe hanger within a subsea wellhead and axially moving the actuation sleeve; at least one positive indicator assembly disposed within the pipe hanger, the indicator assembly having an indicator stem that moves from an extended position to a retracted position when the actuation sleeve moves to the lower position; a control unit adapted to be located at a surface platform; and a communication line extending between the positive indicator assembly and the control unit, the control unit providing a fluid pressure thru the communication line that changes when the indicator stem moves to the retracted position.
