Abstract: 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.

Abstract: An apparatus includes a tube having at least one flow outlet in communication with an interior of the tube. The apparatus includes valves for selectively connecting the flow outlet to one of a fluid return line and an inlet of a fluid pump. The apparatus also includes valves for selectively connecting the outlet of the pump to the fluid return line and closing the pump outlet. A method includes returning mud from a wellbore into a riser extending between the wellbore and a drilling unit on the surface of a body of water. Flow from a tube in the riser is selectively diverted to an inlet to a fluid pump or a mud return line extending from the tube to the drilling unit. When the flow is diverted to return mud flow in the riser is stopped above the tube. When flow is diverted to the inlet of the pump, the pump is operated to lift the mud to maintain a selected mud pressure in the wellbore.

Abstract: Present embodiments relate to a riser bolt torque device that is configured to couple a first riser joint to a second riser joint to form a riser of a subsea drilling system. The riser bolt torque device includes a first arm and a second arm, multiple torque tools supported on the first arm and the second arm, and one or more actuators configured to drive the first arm and the second arm to pivot relative to one another from an open configuration to a closed configuration to enable alignment between the multiple torque tools and a flange of the first riser joint.

Abstract: A rotating control device (RCD) system includes a housing having a bore, a seal element positioned within the housing, a piston assembly supported within the housing and configured to drive the seal element to seal the bore, and a bearing assembly supported within the housing and configured to enable the seal element to rotate relative to the housing. The bearing assembly includes a first bearing section positioned between the housing and the seal element and a second bearing section positioned between a piston of the piston assembly and the seal element. The piston assembly is configured to selectively actuate the seal element into a first configuration, where the seal element extends into the bore and seals with a tubular therein, and a second configuration, where the seal element extends entirely through the bore and seals the bore without a tubular extending therein.

Abstract: 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.
