Abstract:
1. A tubing hanger adapted to land in a tubular element and comprising a coupling assembly adapted for establishment of a hydraulic coupling between the tubing hanger and the tubular element, wherein the coupling assembly comprises: a coupling element adapted to move radially between an outer coupled position and an inner non-coupled position, which coupling element exhibits an outer surface adapted to establish said hydraulic coupling with an opposite and inwardly facing surface of the tubular element when forced against it, as the coupling element comprises a hydraulic channel adapted to align with a hydraulic channel in the tubular element, and wherein the coupling element comprises a radially inner actuation surface; an actuation element with a contact surface adapted to exert an actuation force onto the inner actuation surface in a radially outward direction; wherein the actuation element exhibits an elongated shape and comprises two actuation sections which are adapted to be exposed to a radially outward directed force from an actuation arrangement; wherein the contact surface is arranged with a distance crosswise to the radially outward direction from both of said actuation sections; and wherein the actuation element is adapted to be moved in the radial outward direction in such way that the movement in the radial outward direction of at least one of the two actuation sections stops after radial movement of the contact surface stops, wherein the movement of the contact surface is halted as the coupling element reaches the coupled position.
