    摘要: A flowline selector device has a housing with a single passage at the upper end and two or more passages at the lower end. A tube connects to the upper end and has a lower end that is offset from the axis of the housing. Reciprocating the tube up and down and rotating it causes the tube to index between the various ports in the lower end of the housing. The lower end of the tube stabs into cylindrical bores in each port. A piston located at the upper end of the tube cooperates with an orientation sleeve to cause the indexing and reciprocating movement.

    摘要: A subsea well having inner and outer tubular housings has features to reduce bending movement of the inner housing within the outer housing. The inner and outer housings have mating wedging surface axially spaced apart from each other. These tapered surfaces are spaced so as to cause the inner housing to wedge within the outer housing as it is lowered into place. A latch latches the inner housing to the outer housing once lowered into place. A sleeve of elastomeric material locates on the exterior of the lower extension of the inner housing. This sleeve extends downward a selected distance to prevent bonding of cement to the inner housing in this area. Part of the latch is mounted to a ring clamp that releasably mounts to the outer housing.

    摘要: An apparatus for performing operations on an offshore well includes a subsea wellhead assembly. A riser extends from the subsea wellhead assembly to a surface vessel. A tool connects to a running string and is lowered through the riser into the wellhead assembly for performing operations at the wellhead assembly. A subsea controller is located adjacent the subsea wellhead assembly. The subsea controller controls the operation of the tool. A surface controller is positioned on the surface vessel, and is in communication with the subsea controller via a control line extending downward from the surface controller to the subsea controller. The control line extends downward from the surface controller along an exterior of the riser.

    摘要: A wellhead load ring constructed in the shape of a C-ring is pre-installed in a wellhead in a storage position that maintains full bore of the wellhead. The load ring is secured in this position by shear pins. The shear pins are sheared by a tool that pushes the load ring into an operational position where it rests on a landing shoulder of a support ring. The load ring is further secured in this position by one of several latching methods.

    摘要: A dog-style connector with a fail-safe mechanism for a marine riser system that connects a box portion and a pin portion of a riser. An actuator housing is affixed to an external surface of the box portion. The actuator housing has an outer bore and a threaded inner bore. An actuator body is threadably received in the inner bore. The actuator body has a hex head on its first end. The actuator body has a threaded fastener bore extending from the first end for receiving a threaded fastener. The actuator body has a second end that has a stem receptacle formed therein. The fastener bore is in communication with the stem receptacle. An actuator head, which includes a flange and a stem, is provided wherein the stem is positioned within the stem receptacle for sliding engagement therewith. Threads formed on the threaded fastener engage a threaded fastener receptacle formed in the stem of the actuator head. A dog interfaces with the flange and is slidably mounted with respect to the actuator body for engaging a groove in the pin portion of a riser. A threaded fastener is provided to be threadably received in the threaded fastener bore of the actuator body.

    摘要: A running tool for installing a casing hanger in a subsea conductor also serves to wash cement from the annulus surrounding the casing hanger. The running tool includes a tubular tool body which connects to a string of conduit. An internal sleeve mounts in the interior of the tool body for rotational movement only. A torque member lowers through the conduit to the internal sleeve for rotating the internal sleeve. A wash port extends from the interior of the tool body to the exterior of the tool body. An external sleeve mounts to the exterior of the tool body for axial movement between a closed position, closing the wash port, and an open position, opening the wash port. A linking mechanism between the internal and external sleeve causes rotary movement of the internal sleeve to move the external sleeve axially.

    摘要: A tieback system for a subsea well utilizes a tieback connector. The tieback connector has a body that lands on a wellhead housing located on a sea floor. A funnel extends downward from the body for sliding over the wellhead housing. A lockdown sub is carried by the body and has a set of tapered threads on its exterior. A lock ring is carried by the lockdown sub. The lock ring has an exterior profile for engaging an internal groove formed in the wellhead housing. Rotating the lockdown sub moves it downward from a recessed position to a locking position. In that position, the rotation causes makeup to the threads and causes the lock ring profile to tightly engage the groove in the wellhead housing.
