A gooseneck conduit assembly includes a gooseneck conduit including a vertically-extending portion, an upset formed on the vertically-extending portion, an alignment key extending laterally from the vertically-extending portion, and a lower coupling at a lower end of the vertically-extending portion; a second conduit configured to connect to an auxiliary fluid line connected to and extending along a riser string that extends to a subsea wellhead, the second conduit including a receiving end configured to form a connection with the lower coupling; and a frame configured to be connected to the riser string. The frame includes an upper bracket vertically offset from a lower bracket to which the second conduit is secured, an alignment groove configured to slidably receive the alignment key so as to maintain a coaxial alignment between the vertically-extending portion of the gooseneck conduit and the second conduit, and a locking member pivotally coupled to the upper bracket.

Gooseneck connector system

A connector system includes a first riser joint configured to form part of a riser. The first riser joint includes a pin. The connector system also includes a connector configured to couple to a wellhead assembly. The connector includes multiple collet segments that are configured to move radially-inwardly to engage the pin of the first riser joint.

Riser collet connector systems and methods

A connector system and method, of which the connector system includes a first conduit having a lower coupling and a first alignment feature, and a frame configured to be coupled to an oilfield tubular, and configured to receive the first conduit and a second conduit. The frame includes a second alignment feature configured to mate with the first alignment feature such that the lower coupling is aligned with the second conduit, and the first alignment feature is configured to slide vertically with respect to the second alignment feature such that the lower coupling is brought into engagement with the second conduit while the first and second alignment features are mated together.

A tool catcher system that includes a housing. The housing defines a bore that receives a tool. The tool catcher system includes a plurality of ring segments that move radially inward and radially outward to selectively couple to and uncouple from the tool. A spring plate supports the plurality of ring segments. An actuator plate couples to the spring plate. A plurality of shafts couple the actuator plate to the spring plate. An actuator system moves the actuator plate and the spring plate in a first direction to release the tool.

Tool catcher system

A tracking system includes a tether, a buoyant transmitter assembly coupled to a first portion of the tether, an attachment component coupled to a second portion of the tether. The attachment component is configured to couple the tracking system to an object, and the tether enables the buoyant transmitter assembly to float above the object while the object and the tracking system are submerged in a fluid.

Tethered tracking system

A system for drilling and/or producing a subsea wellbore comprises a primary BOP comprising a primary ram BOP. The secondary BOP is connectable to a subsea wellhead such that the secondary BOP is positioned between the primary BOP and the subsea well-head, in which the secondary BOP comprises a shear ram BOP.

Blowout preventer shut-in assembly of last resort

A system and method for guiding a dropped suspended load includes a safety winch, safety buoy, and safety anchor spaced relative to one another and an offshore rig's lifting system so that the dropped load falls away from certain seabed locations and to a safe landing area. A safety winch cable runs from the safety winch to the safety buoy, and from the safety buoy to a connection to the load. The load, when in a run-away state, falls away from vertical and toward a predetermined safe landing spot on the seabed floor. The safety buoy is then used to locate the load.

Safety system and method for guiding a dropped suspended load away from equipment and to a safe landing area

A multi-pressure flange is disclosed that includes a first set of fasteners comprising four fasteners in a first rectangular pattern for attachment in a first pressure rating and a second set of fasteners comprising four fasteners in a second rectangular pattern in which the first rectangular pattern is perpendicular to the second rectangular pattern. The second set of fasteners is selectively combinable with the first set of fasteners for attachment in a higher second pressure rating. The flange may include a recess to receive sealing component and a receptacle configured to receive a pipe fitting. Systems and methods including the multi-pressure flange are also disclosed.

Multi-pressure flange connection

Systems for accessing a well bore including a BOP stack with a universal intervention interface are disclosed. In some embodiments, the system includes a BOP stack and a valve assembly. The BOP stack has a throughbore and is installable on a well such that the throughbore is in fluid communication with the well bore. The valve assembly is coupled to the BOP stack and includes a fluid flowpath in fluid communication with the BOP stack throughbore, two valves connected in series and disposed along the fluid flowpath, the valves operable to control flow through the fluid flowpath, and a ROV panel including ports accessible by a ROV for operation of the two valves.

BOP stack with a universal intervention interface

A system for drilling and/or producing a subsea wellbore comprises a primary BOP comprising a primary ram BOP. In addition, the system comprises a secondary BOP releasably connected to the primary BOP, the secondary BOP comprising a secondary ram BOP. The primary rain BOP is actuatable by a first control signal. The secondary ram BOP is actuatable by a second control signal. The secondary rain BOP is not actuatable by the first control signal.

An integrated side-entry sub with grease injection flow tubes is adapted for making up in a drill string and includes a port to receive a cable, such as a wire line. A first pedestal, mounted within a cutout of the side entry sub, provides entry for the cable into the entry port. The first pedestal receives a first flow tube, which couples to a lower connector manifold. The lower connector manifold further provides a grease injection port. A second flow tube, coupled to the lower connector manifold, runs to an upper connector manifold. The upper connector manifold further provides an grease return port, as well an the entry point for cable into the sub.
