  • Publication number: 20220221057
    Abstract: The present invention concerns a gasket assembly (1) for sealing between conduits passing through two respective bodies. The gasket assembly comprises a primary seal (10), wherein the primary seal comprises a first sealing surface (14) adapted to form a seal with the first body of said respective bodies, and a second sealing surface (15) adapted to form a seal with the second body of said respective bodies. The primary seal is coupled to a primary seal carrier (30), the primary seal carrier comprising one or more secondary seals (43a, 43b), the one or more secondary seals being adapted to form a seal with one or more of the first and second bodies.

  • Patent number: 9631438
    Abstract: A connector is disclosed for connecting components of a subsea conduit system extending between a wellhead and a surface structure, for example, a riser system. Male and female components are provided, and a latching device to releasably latch the male and female components together when the two are engaged. The male and female components incorporate a main sealing device to seal the male and female components together to contain the high pressure wellbore fluids passing between them when the male and female components are engaged. The latching device also incorporates a second sealing device configured to contain fluids when the male and the female components are disengaged, so that during disconnection, any fluids escaping the inner conduit are contained.

  • Patent number: 9362662
    Abstract: A connector for connecting power or control systems infrastructure such as for example subsea infrastructure, said connector comprises a male component and a female component, the male and female components comprising cooperating mating surfaces and means for locking the male and female components together, the locking means being retractably mounted within one of the male or female components but extendible from that component into the other of the male or female components to lock the two components together against axial and rotational movement while providing a snag free release when the locking means is in the retracted position. The means for locking includes pivotal levers with free ends that are to enter recesses of the male component and that are to be held in locking position by a moveable control coupler. An electrical coupler located within the female component is to be raised to engage a corresponding coupler on the locked in position male component.

  • Patent number: 9045971
    Abstract: A subsea system for intervention or deployment comprising a spool (9, 109) adapted for mounting subsea, a carrier (4, 4, 5?, 34, 104) adapted for suspension from a surface vessel or platform, a guide line (8, 108) wound on the spool, the free end of the guide line connected to the carrier and means (11) for driving the spool in one direction to pay out a length of guide line as the distance between the spool and the carrier is increased and in the other direction to reel in the length of guide line as the distance between the spool and the carrier decreases.

  • Patent number: 8317234
    Abstract: A connector for connecting a plurality of components having cooperating faces together. The connector includes a plurality of dogs for locking the cooperating faces of upper and lower conduits together. The plurality of dogs are movable between an open position and a locked position. A hydraulic piston moves the plurality of dogs into the locked position. The connector includes an annular collar that retains the plurality of dogs in the locked position once the hydraulic piston is withdrawn. When the annular collar is removed, the plurality of dogs return to an unlocked position thereby allowing separation of the cooperating faces without snagging of the plurality of components.
