    摘要： A wellhead system comprising an outer wellhead housing (54), an inner wellhead member (56), and an annulus therebetween. The inner wellhead member (56), such as a casing hanger, is adapted to land in the outer wellhead housing (54). The outer wellhead housing (54) may comprise a wickers (52) formed in a hardened metal inlay (68). Alternatively, or in addition to the wickers (52) formed in the outer wellhead housing, wickers (50) may be formed in a hardened metal inlay (72) in the inner wellhead member (56). An annular metal seal (64) may be disposed in the annulus and driven into the wickers (52) to seal the annulus between the inner wellhead member (56) and the outer wellhead housing (54) and to axially restrain the seal (64) within the annulus.

    摘要： A subsea well connector for connecting a tubular member to a subsea wellhead assembly includes a tieback connector having an annular stationary connector body that circumscribes a portion of an annular moveable connector body. A tie rod with a tie rod profile extends axially from the stationary connector body. A dog ring circumscribes the tie rod and is moveable between a lockdown open position where the dog ring is spaced from the tie rod, and a lockdown engaged position where a dog ring inner diameter profile engages the tie rod profile, to axially couple the stationary connector body and the moveable connector body. An annular piston circumscribes the dog ring and has a region with a reduced inner diameter that engages an outer diameter of the dog ring to retain the dog ring in the lockdown engaged position. A cylinder circumscribes the annular piston, defining a lockdown piston cavity.

    摘要： A mechanical lockdown system for a subsea wellhead connector includes a lockdown member or plate that engages with a tie rod that is connected to the wellhead assembly. The lockdown system includes a support member that is permanently secured to an annular ring through which the tie rod passes. The lockdown system also includes a first handle and a second handle that are installed using a plunger or spring loaded system such that mechanical lockdown system can be easily moved from a lockdown open position to a lockdown engaged position as and when desired with minimal ROV interface.

    摘要： A structural health monitoring system (25) for a marine composite riser string (30) is provided. Each riser pipe section (31) includes a cylindrical form having an axis (A) and also a carbon epoxy matrix (37). A sensor (38) is associated with (e.g., embedded in) and substantially circumscribes the riser pipe section (31). The sensor (38) includes a polyvinylidene fluoride laminate (35) and electrodes (36) (e.g., conductive silver ink coating) so that the sensor (38) generates electricity at the electrodes (36) responsive to mechanical stresses and strains of the riser section (31), including vibrations. The system (25) can also include a data acquisition system (79) and digital signal analyzer (70) to analyze signals responsive to the generated electricity at the electrodes (36) of sensors (38) and to provide health monitoring and damage detection for the marine riser pipe string (30), including impact damage and fatigue crack initiation. The system (25) can further include a subsurface (23) energy storage device (40) and a plurality subsurface microelectromechanical devices (42) coupled to the subsurface (23) energy storage device (40).

    摘要： A wellbore system (20) comprising a housing assembly (22) and a hanger assembly (24). The hanger assembly (24) comprises an actuation member (36) that interacts with a portion (38) of the housing assembly (22) when the hanger assembly (24) is positioned at a desired location in the housing assembly (22). The hanger assembly (24) also comprises a load member (28) that is adapted to extend between the hanger assembly (24) and the housing assembly (22) to enable the housing assembly (22) to support the hanger assembly (24). The load member (28) is carried into the wellbore in a retracted position. When the actuation member (36) interacts with the housing assembly (22) at the desired location, the actuation member (36) actuates the load member (28) to expand outward to extend between the hanger assembly (24) and the housing assembly (22). The actuation member (36) is adapted to transfer a lifting force from the surface to the load member (28) to enable an over-pull test of the hanger assembly (24) to be performed.
