Abstract: A seal for sealing an annulus between an outer tubular wellhead member and an inner tubular wellhead member is described. In embodiments, the seal is an annular sealing ring that has a plurality of circumferentially spaced apart sealing ring grooves extending at least from a first end to a second end of the sealing surface of at least one of the wellhead members. When the seal is energized, fouling on the sealing surface is urged toward and then through the slot, axially away from the sealing surface.

Abstract: A pressure mitigating device is used to reduce pressure in a void within a wellhead housing. In one embodiment, the pressure mitigating device includes two plates that define a void between them. Increased pressure in the wellhead housing causes the plates to elastically displace towards each other. The plates contact each other, limiting the displacement prior to plastic deformation.

Abstract: A pipe connection includes a box that mates with a pin. A box slot extends through a side wall of the box at a point adjacent the rim for alignment with a pin slot formed on the pin. Each of the slots has a circumferential dimension and an axial dimension that is less than the circumferential dimension. The pin slot has a greater circumferential dimension than the box slot. A locking key has a pin section and a box section located within the pin slot and the box slot, respectively, when the key is installed. The pin section has teeth that bite into the pin slot. The key has a width substantially the same as the circumferential dimension of the box slot.

Abstract: A method and apparatus for forming a tubular from a composite material. The composite material includes fibers and epoxy resin that are formed into plies that are wound around an axis to form an annular member. The fibers in each ply are arranged axially and hoopwise. The axially oriented fibers are angled from about 10° up to about 20° with respect to an axis of the tubular. The hoopwise fibers are wound in the plies ranging from about 60° at the innermost ply up to about 90° in the outermost ply. The hoop fibers in the intermediate plies are arranged at increasing angles with distance away from the innermost layer. Transitioning the hoop fiber alignment in the successive plies better distributes hoop stress through the wall of the tubular thereby reducing stress concentrations on the innermost ply.

Abstract: A running tool generates signals in response to setting of a subsea wellhead device that correspond to actual rotation and displacement of the running tool in the subsea wellhead. The running tool includes an encoder that generates a signal corresponding to the number of rotations of a stem of the running tool relative to a body of the running tool. The running tool also includes an axial displacement sensor that generates a signal corresponding to the axial displacement of a piston of the running tool relative to the body. The signals are communicated to the surface using an acoustic transmitter located on the running tool and an acoustic receptor located proximate to a drilling platform at the surface. The signals are communicated to an operator interface device from the receptor for further communication in a manner understood by an operator.

Abstract: A tubular connector connects two tubulars of a string of tubular members. The tubular connector has a pin end tubular member having an axis and a pin end. A pin end flange is positioned on an outer diameter of the pin end and has an undercut adjacent the union of the pin end flange with the pin end. The tubular connector also has a box end tubular member having a box end. A box end shoulder is adjacent the union of the box end with the box end tubular member. The box end shoulder has an undercut thereon. The pin end is secured to the box end so that the pin end tubular member and the box end tubular member are joined, stresses applied to the pin end tubular member and the box end tubular member are distributed through the undercuts.

Abstract: A riser for use in subsea operations that is parked subsea deployed as needed onto wellheads disposed proximate where the riser is parked. A base anchored into the seafloor provides a pedestal for parking the riser. The riser emits a beacon signal so it can be located when needed. When parked, the riser can be kept in a vertical orientation by a buoyancy module mounted on an upper portion of the riser. A workboat, or other vessel, attaches to the parked riser and positions it onto a designated wellhead. An extension connects the riser to platform or other vessel above the sea surface.

Abstract: A bridging hanger with an expandable anchoring mechanism lands on a casing hanger in a subsea wellhead and actuates to anchor to the casing hanger. The anchoring mechanism includes a tubular main body, and a tubular sealing sleeve. The tubular sealing sleeve is coaxial with and mounted on an exterior diameter portion of the tubular main body. The body is moveable from an upper run-in position to a lower set position relative to the sealing sleeve. The anchoring mechanism also includes a first and second locking ring, both carried by the sealing sleeve. The first locking ring engages a profile within an interior of the casing hanger in response to movement of the main body from the run-in to the set position. The second locking ring locks the tubular main body in the set position in response to movement of the main body from the run-in to the set position.

Abstract: A wellhead seal assembly that forms a metal-to-metal seal between inner and outer wellhead members. A bi-metallic U-shaped seal with legs having a low yield metal on the outer portions. During installation of the seal assembly, the legs of the seal are forced outward against the surfaces of the wellhead members, by pressurization of a interim non-metallic seal which forces a wedge into the U-shaped seal, causing localized yielding of the low yield metal to fill defects on wellhead member surfaces.
