  • Patent number: 7503391
    Abstract: A tieback connector for attaching a riser to a subsea production assembly is provided. The tieback connector includes a main body adapted to be coupled to the subsea production assembly having a central passageway sufficiently large to pass an end of the riser string therein and a connector positioner coupled to the main body, which is adapted to secure the tieback connector around a circumferential surface of a wellhead of the subsea production assembly. The tieback connector further comprises an aligning extension portion defined by a funnel-shaped tip, which aids alignment of the riser terminus during landing of the riser string onto the wellhead. The tieback connector secures the riser to the wellhead.

  • Patent number: 6824171
    Abstract: A tubular connection 7 is provided for connecting an upper tubular member 10 with a lower tubular member 12. A radially movable latch body 20 is positioned outward of the tubular members. Outer load flanks 25 on the latch body are slidably engageable with inner load flanks 24 on the tubular members. A radially projecting member 32 and a corresponding guide recess 34 are provided for guiding the latch body with respect to one of the tubular members. A safety actuator 30 and corresponding mating surface 38 may also be provided for urging the latch body outward.

  • Patent number: 6698712
    Abstract: The ball valve assembly 10 includes a valve body 12, a ball 14, a seat ring 30, a support ring 40, and an actuator sleeve 50 surrounding the ball and axially moveable within the valve body for rotating the ball between the open position and the closed position. A plurality of seals seal with the seat ring, the actuator sleeve, the support ring, and the valve body. The actuator sleeve 50 maintains fluid pressure within the valve body. The ball, support ring and seat ring are each formed from a selective material to enhance life of the ball valve assembly. A pair of pins 80, 82 each extend in a slot within the ball and holes in the sleeve, and preferably the pair of pins and the ball rotate with respect to the sleeve as the sleeve moves axially within the valve body.
