A system for coupling a first pipe segment to a second pipe segment includes a pin end including a flange. The system includes a box end having a recess configured to receive the pin end, a face of the box end abutting the flange. The system includes a coupling assembly joining the first pipe segment to the second pipe segment including a split ring arranged proximate the flange and a sleeve, wherein threads of the sleeve engage first mating threads on the split ring and second mating threads on the box end.

The present invention concerns a connection system 1 for a marine drilling riser 10 having one or more auxiliary lines 20, the connection system comprising: a moveable coupling member 30 having at least one first connector and at least one second connector coupled to the at least one first connector, wherein the at least one second connector is adapted for engaging with at least one connector of an auxiliary line of the marine drilling riser The connection system further comprising a control line support 18 for fixing at or adjacent an outer surface of the marine drilling riser; a control line supported by the control line support and for attachment to the moveable coupling member; and a tailing line for attachment to the moveable coupling member.

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.

The invention provides well control system for a riser. The well control system comprises a riser assembly and at least one flow meter. The at least one flow meter is configured to be mounted on the riser.

Systems and methods for control/monitoring of internal equipment in a riser assembly are disclosed. The method includes running a tool through at least a portion of an internal bore of a riser assembly associated with a well, and outputting a control signal from a first wireless communication interface disposed along the internal bore of the riser assembly. The first wireless communication interface is coupled to a communication system on the riser assembly. The method also includes receiving the control signal at a second wireless communication interface disposed on the tool, and actuating at least one equipment component of the tool in response to the second wireless communication interface receiving the control signal.

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.

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.

Blowout preventers having bodies without flanged necks are provided. In one embodiment, a blowout preventer stack includes first and second blowout preventers having independent and separable main bodies, each including a bore and a ram cavity transverse to the bore. The lower end of the main body of the first blowout preventer is fastened directly to an upper end of the main body of the second blowout preventer without a flanged neck extending the bore between the ram cavities of the first and second blowout preventers. In some instances, the main bodies of the first and second blowout preventers include external connection flanges that extend laterally from ram cavity body portions of the main bodies so as to enable connection of the two main bodies along the sides of the main bodies away from their bores. Additional systems, devices, and methods are also disclosed.

Systems and methods for riser monitoring and lifecycle management are disclosed. The riser monitoring and lifecycle management method includes receiving a signal indicative of an identification of a riser component at a monitoring and lifecycle management system (MLMS), wherein the riser component forms part of a riser assembly. The method also includes detecting one or more properties via at least one sensor disposed on the riser component during operation of the riser assembly, and communicating data indicative of the detected properties to the MLMS. The MLMS stores the data indicative of the detected properties with the identification of the riser component in a database.

The present invention is a connector (5) for a riser equipped with an external locking collar (11). Locking collar (11) cooperates with a male flange (24) of a male connector element (9) and a female flange (23) of a female connector element (8) by means of a series of tenons. The invention also relates to a riser including several sections (4) assembled by a connector (5).
