  • Patent number: 9543695
    Abstract: Connector (100) with locking components (107) about a peripheral section of the connector. The locking components extend in an axial direction engage with the connector (100) at a first end and engage with a connecting part (201) at an opposite locking end with a locking profile (109). A radial locking movement of the locking end is provided by an axial movement of an actuation sleeve (113). The locking components (107) are arranged to pivot in a substantially radial direction, about their section of engagement with the connector (100), into and out of a locking position. The connector (100) comprises guiding plates (111) between the locking components (107) in the area of their locking ends. The guiding plates exhibit protective faces (111a) that extend further radially inwards than the locking profile (109) of the locking components (107) when the latter are in the outwardly pivoted position.

  • Patent number: 9080408
    Abstract: A well head system for application in sub sea well exploration comprising a well head (23) having a well head housing secured to a well casing, at least one valve stack, e.g. a BOP (1) located atop said well head (23). The valve stack is removably locked on a well template (15) supporting said well head by a plurality of locking devices (7). Also described is a locking device comprising two opposite clamping arms (19) hingedly attached to a main frame (21). The Main frame is slidable relative to a spindle (17) and can be selectively secured to the spindle (17).

  • Publication number: 20140334872
    Abstract: An activation mechanism to release a guidepost from a seabed structure is described. The guidepost includes a tubular main body, an operating mechanism at the upper end of the main body, a locking mechanism at the lower end of the main body to enable attachment to the seabed structure, and an interconnecting device arranged inside the tubular main body, and connecting the operating mechanism to the locking mechanism in order to be able to activate the locking mechanism from the top of the guidepost. The operating mechanism includes a rotatable outer sleeve configured to transform a rotary motion to a lifting or lowering motion of the interconnecting device, which in turn elevates or lowers an activation mechanism that influences on at least one locking pawl to be pulled inwards beyond the diametrical dimension of the guidepost to release an engagement with a groove or ledge on the seabed structure.

  • Patent number: 8672366
    Abstract: A coupling arrangement having external threads carried on a first pipe element. A second pipe element carries a radially movable locking member with external locking profiles, and a connection sleeve having internal threads that are threaded onto external threads and internal locking profiles that engage with the external locking profiles. The connection sleeve is moved in a first axial direction towards the first pipe element by rotation on the external threads while the internal locking profiles are in an intermediate engagement with the external locking profiles, until the movement is limited by abutting faces of the internal and external locking profiles. At least one of the abutting faces exhibits an inclination resulting in a pull of the connection sleeve towards an axial direction opposite of the first axial direction when the external locking profiles are moved radially.
