摘要： An offshore method includes providing an elongate support string for extending between a mobile offshore drilling unit and a seabed location. The string has an upper portion and a lower portion, and an articulated joint is provided between the upper portion and the lower portion. The provision of the articulated joint maintains the lower portion of the elongate support string in a substantially vertical orientation and increases the safe operating radius of the mobile offshore drilling unit or increases the speed at which the unit may transit through the sea with objects suspended via the elongate support string.

摘要： Disclosed is a method for reducing friction in a radial drilling application. The method involves coating the interior of a deflector shoe with at least one lubricant. Lubrication of the deflector shoe can be accomplished by applying a dry lubricant to the interior of the deflector shoe, allowing the dry lubricant to harden, and applying a wet lubricant over the hardened dry lubricant. The interior surface of the deflector shoe may be roughened prior to application of the lubricant. The method can further include coating a hose and/or a jet nozzle, and passing the hose and/or jet nozzle through the coated interior of the deflector shoe. The method can further include coating components of a milling cutter, and passing the components of the milling cutter through the coated interior of the deflector shoe. An apparatus for reducing friction in a radial drilling application is also disclosed.

摘要： A hands-free gooseneck flow spool includes a mandrel, a hands-free gooseneck receiver fixedly attached to the mandrel, and a hands-free gooseneck removably attached to the hands-free gooseneck receiver. The hands-free gooseneck receiver includes a lockable gooseneck receiver including a gooseneck receiver end fluidly connected to a mandrel connection end, a rotatable locking collar at least partially disposed within the gooseneck receiver end of the lockable gooseneck receiver, and a plurality of alignment pins. The hands-free goose neck includes a substantially U-shaped gooseneck pipe member including a hose connection end that is fluidly connected to a receiver connection end, a hands-free connection system including a pad-eye track disposed on the U-shaped gooseneck pipe member and a pad-eye shackle movably attached to the pad-eye track, and a plurality of alignment pin receivers disposed near the receiver connection end.

摘要： An actuatable sealing mechanism for sealing a fluid channel provided between two co-axially arranged tubular members having a central longitudinal axis. The actuatable sealing mechanism comprises an elastomeric seal, an axially moveable actuating sleeve member (1400; 2400; 3020) and a radially moveable activating member. The activating member is configured to be moveable in a radial direction in use to translate the actuatable sealing mechanism between an unsealed state and a sealed state. When it is in the sealed state, the activating member axially compresses the elastomeric seal sufficiently to expand the elastomeric seal in the said radial direction to seal the fluid channel.

摘要： 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.

摘要： A connecting assembly for connecting a first body and a second body includes a connector having a plurality of segments and a main piston positioned around at least a portion of the connector. The connector includes: a channel that extends longitudinally through the connector from a first end to a second end; a plurality of teeth formed on an inside of the connector near the first end and near the second end; a first jaw formed of at least one teeth near the first end; and a second jaw formed of at least one teeth near the second end and axially spaced apart from the first jaw. Each of the plurality of teeth has a leading side facing an axial center of the connector, a top side, a contact point at a transition between the leading side and the top side, and a trailing side opposite the leading side. The teeth of the second jaw include: a first tooth axially closer to the axial center of the connector than the remaining teeth of the second jaw and an end tooth axially farther from the axial center of the connector than the remaining teeth of the second jaw.

摘要： A unitized wellhead assembly includes a lower wellhead housing and an upper wellhead housing interconnected by internal and external threads and pressure sealed via a housing seal that creates a unitized body. The unitized wellhead assembly accepts casing and tubing hanger assemblies containing a plurality of individual retainer segments that engage mating grooves in the unitized body and also retains the casing and tubing hangers in place while containing the wellbore pressure. By eliminating the porting for external actuation devices that pass through the wall section of a wellhead housing, the potential for accidental release of wellbore gasses or fluids to the atmosphere and creation of a potentially hazardous or deadly situation is eliminated. Additionally, the configuration of the segmented retainers reduces high stresses when the retainers are forced outward and eliminates the potential to yield a retainer ring beyond the point of being able to return to its original shape.

摘要： A joint assembly allows a riser system to have a weak point that can fail at a known location and tension value without reducing the riser pressure containment capacity. The joint assembly includes a standard riser pipe machined to remove material, for example, to form a groove. The joint assembly also comprises means for restoring pressure capacity. For example, the means for restoring pressure capacity include a combination of a thick-bodied clamp and a split insert ring. The split insert ring can bridge between the groove and the clamp, at least partially transferring the pressure load contained inside the machined pipe to the clamp.
