A system and method for installing a tubular in a wellbore, of which the method includes coupling a fluid connector tool to a lifting assembly, coupling a casing fill-up and circulation seal assembly to the fluid connector tool, and coupling two segments of casing together to form a casing string. At least one of the segments of casing is fluidically coupled to the casing fill-up and circulation seal assembly. The method also includes running the casing string into a wellbore, pumping a first fluid from the lifting assembly, through the fluid connector tool and the casing fill-up and circulation seal assembly, and into the casing string as the casing string is run into the wellbore, de-coupling the casing fill-up and circulation seal assembly from the fluid connector tool, and coupling a drill-pipe seal assembly to the fluid connector tool.

A connector is configured to couple a first annular member to a second annular member. The connector includes a rotatable plate and multiple lock segments. The connector further includes a coupling assembly that is configured to couple the rotatable plate to the multiple lock segments, such that rotation of the rotatable plate in a circumferential direction drives the plurality of lock segments along a radial axis to adjust the connector between an unlocked configuration and a locked configuration.

The system for making or breaking the riser includes a robotic system. The robotic system includes one or more robotic arms configured to be disposed on a spider deck, and one or more riser-connection manipulation tools each having a camera and being configured to manipulate a riser connection, the camera being configured to capture an image of an object, wherein each robotic arm is configured to couple to one riser-connection manipulation tool. Further the system for making or breaking the riser includes a control system. The control system includes a robot controller in communication with the one or more robotic arms and configured to control the one or more robotic arms. The system for making or breaking the riser is configured to analyze the image to determine the location and orientation of the object and transmit the location and orientation of the object to the robot controller.

Systems and methods for a riser coupling are disclosed. A riser sensor unit for sensing engagement of a riser tool with a riser coupling includes a first sensor attached to a sub of the riser tool. The first sensor is configured to generate a first signal upon detecting contact with the riser coupling, and an intrinsic safety barrier is configured to transmit the first signal to a control system.

A casing mandrel includes a body having a first end and a second end, the first end being configured to be coupled to an upper portion of a casing string and the second end being configured to be coupled to a lower portion of the casing string, a downhole tool operatively coupled to an outer surface of the body, a tool port defined in the body and extending between the downhole tool and an interior of the body and thereby placing the downhole tool in fluid communication with the interior of the body, and at least one degradable plug disposed within the tool port to prevent wellbore debris from obstructing fluid communication between the interior and the downhole tool, wherein the degradable plug degrades over time.

High-strength, fatigue-resistant pipe connectors suitable for use in offshore risers, tendons and pipelines, such as may be connected to floating production systems (FPSs) principally used in the production of oil and gas. The present connectors include tubular pin and box components with mating frusto-conical, concentrically-grooved mating surfaces which threadingly interlock, and non-threaded (e.g., flat) mating surfaces that seal and preload (e.g., preload at least a portion of each component in compression), via axial advancement of the pin component into the box component. In such connectors, axial movement of the pin into the mating box results the in radial expansion of the box and radial contraction of the pin until the concentric thread patterns match and interlockingly snap into the connected position.

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).

A riser top connector assembly (20) is shown. The assembly (20) includes a first connector part (21) arranged on a flexible jumper prepared for connection with a second connector part (40) arranged on top of a marine riser tower assembly projecting from the seabed. The first connector part (21) is provided with suspension means adapted to engage with supporting means in order to be supported and be able to tilt in the marine riser tower assembly. The first connector part (21) includes a housing (22) that receives an extendable termination hub (23) having a clamp connector (24) attached thereto. The jumper termination hub (23) is alignable with a riser hub (44) on the second connector part (40) when the first connector part (21) is being tilted relative to the marine riser tower assembly.
