    Abstract: A seal assembly is provided. The seal includes an upper body; a lower body having a seal for sealing between a first wellhead system component and a second wellhead system component; and a space-out mechanism disposed between the upper body and the lower body, the space-out mechanism comprising a ramp ring having at least one tapered surface. The upper body has at least one tapered surface configured to interface with the at least one tapered surface of the ramp ring, the ramp ring is configured to rotate relative to the upper body and the lower body, and the at least one tapered surface of the ramp ring and the at least one tapered surface of the upper body are configured to bear against each other to rigidize the system.

    Abstract: A method for operating an apparatus for installing a tubing hanger in a subsea wellhead or X-mas tree without hydraulic cables from the surface and without valves for controlling hydraulic functions. The method includes: providing an apparatus for installing the tubing hanger; preparing the apparatus for installation; actuating the tubing hanger's locking function via pressurized completion fluid that causes direct actuation of ring pistons that are arranged to operate the locking sleeve and the locking segments of the tubing hanger; verifying the tubing hanger is locked; and releasing the apparatus mechanically or hydraulically from the installed tubing hanger.

    CPC classification number: E21B47/117 ,  E21B33/043

    Abstract: An assembly includes two tubular elements, a primary and a secondary seal arranged between the two tubular elements, a seal cavity formed between the two tubular elements and the primary and the secondary seal, and a seal monitoring apparatus having a housing and a position sensor. The housing has a chamber enclosing a separator which divides the chamber into a first and a second sub-chamber. The first sub-chamber is fluidly connected to the seal cavity and is filled with a hydraulic fluid. The separator is movable in a first direction relative to the housing to increase a volume of the first sub-chamber and decrease a volume of the second sub-chamber, and in a second direction to decrease the volume of the first sub-chamber and increase the volume of the second sub-chamber. The position sensor generates an electrical signal which represents a position of the separator relative to the housing.
