Abstract: A gooseneck conduit system for use with a telescoping joint of a subsea riser. In one embodiment, a riser telescoping joint includes a tube, and a gooseneck conduit assembly affixed to the tube. The gooseneck conduit assembly includes a plurality of gooseneck conduits and a locking mechanism. The gooseneck conduits extend radially from the tube. The locking mechanism engages a locking pin affixed to the tube to secure the gooseneck conduit assembly to the tube. Each gooseneck conduit couples to an auxiliary fluid line secured to the telescoping joint.

Abstract: A gooseneck conduit system for use with a telescoping joint of a subsea riser. In one embodiment, a riser telescoping joint includes a tube and a gooseneck conduit assembly affixed to the tube. The gooseneck conduit assembly includes a gooseneck conduit extending radially from the tube, and a tenon projecting from a rear face of the gooseneck conduit. The width of the tenon increases with distance from the rear face. The riser telescoping joint also includes a mortise channel extending along the length of the tube. The mortise channel is interlocks with the tenon and laterally secures the gooseneck conduit assembly to the tube.

Abstract: A system including a modular riser gas handling system configured to couple to and be disposed vertically below a telescoping joint, wherein the modular riser gas handling system includes a diverter assembly configured to couple to and divert a flow of material into and out of a riser, and an annular blow out preventer (BOP) assembly configured to couple to the diverter assembly.

Abstract: A fluid recovery system is provided. In one embodiment, the fluid recovery system includes a telescoping joint of a marine riser having an inner barrel and an outer barrel configured to extend and retract with respect to one another when installed as part of the marine riser. A drip pan is coupled to the outer barrel to enable the drip pan to catch fluid, such as drilling mud, leaking from the telescoping joint between the inner barrel and the outer barrel. In this embodiment, the fluid recovery system also includes a pump and a return conduit that are coupled to enable the pump to pump caught fluid from the drip pan back into the telescoping joint via the return conduit. Additional systems, devices, and methods are also disclosed.

Abstract: A seal sub system for the connection of fluid lines, including first and second fluid lines, each including a terminal end with an inner diameter. A seal sub includes an inner channel and first and second pin ends, one pin end removably insertable in the fluid line terminal end with the other pin end extending from the fluid line terminal end. A seal forms a seal between the seal sub and the inner diameter of the first fluid line terminal end. The extending pin end is configured to be inserted into the terminal end of the second fluid line to establish a sealed fluid connection between the first and second fluid lines.

Abstract: A hang-off assembly for supporting a riser string from an off-shore drilling rig. The hang-off assembly includes a housing with a passage through the housing and an open section allowing access to the entire length of the passage from outside the housing. The assembly also includes a gate member movable relative to the housing from an open position to a closed position, the gate member preventing access to the passage through the open section when in the closed position. A motor moves the gate member between the open and closed positions. An adapter attachable to the riser string includes a profile landable in the housing to support the riser string when connected to the adapter.

Abstract: A new seal system for a marine riser telescoping joint is revealed. The sealing face of the seal has tapered upper and/or lower tapered surfaces. The upper and/or lower ends can have a taper of about 1-15 degrees or alternatively the surrounding housing can have the taper with the seal ends either straight cut or tapered so that the combined tapers are in the stated range. The sealing elements are preferably nitrile or polyurethane and preferably without inserts. The upper and/or lower ends of the seal can have projections or depressions to aid in end sealing and eliminate the need for end seal rings. The new seals can be used individually or in stacks in a single housing.

Abstract: A wheel apparatus is provided for measuring by rolling contact a dimension of an elevated temperature surface. The device is particularly useful for measuring the length of product in a continuous casting machine. The apparatus includes an elongated arm having an internally cooled wheel rotatably mounted at one end thereof. The arm is pivotally movable about a mount at an end of the arm opposite from the one on which the wheel is mounted. The mount biases the arm to a position in which the longitudinal axis of the arm is normal to the adjacent surface of the cast product. The biased mount permits pivotal deflection of the arm upon contact of the wheel by cast product moving in either a forward or reverse direction. The arm has at least one longitudinal cooling fluid passage which only registers with a cooling fluid supply passage in the arm mount when the arm is in the deflected positions thereof. Generally, air is supplied through the mount to cool the arm and outer surface of the wheel.
