  • 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.
