  • Patent number: 9863202
    Abstract: Systems and methods for using propellant as a force generator in component actuation are disclosed. One embodiment may take the form of a method including deploying at least one component to a subsea location, controlling operation of the at least one component using a control system, and igniting a propellant. The ignition of the propellant actuates the at least one component. Another embodiment may take the form of a subsea system including a control system, a propellant system in communication with the control system, and a component in communication with the propellant system. The propellant system is ignitable by the control system upon receipt of a ignite signal and upon losing communication with the control system after being placed in an armed state by the control system. The component is actuatable by the propellant system after ignition of the propellant system.

  • Publication number: 20060157235
    Abstract: A termination and anchorage for steel helical segmented steel tubing bundles includes a set of multiple separable anchor blocks to which the individual tubes in the bundle can be attached and a clamp assembly for securing and supporting the set of anchor blocks. Multiple comating annular arcuate outer anchor blocks for the outer tubes in the tubing bundle surround a central anchor block, for the center tube in the tubing bundle. The aggregation of anchor blocks is compactly assembled and held together by surrounding the assembled blocks with a separable clamp assembly.

  • Publication number: 20060079107
    Abstract: A subsea connector system is used to connect internally mounted couplers to provide sealed conduits for subsea operations. The system has a removable (outboard) connector and a fixed (inboard) connector each with a housing having special geometric properties that facilitate alignment and connection of the couplers. The latching mechanism has a latch pin in the fixed connector and a latch sleeve in the removable connector for receiving and latching to the latch pin. The couplers (male and female) and the latching mechanism are located within the housings of the fixed and removable connectors to provide protection for the components from damage during storage, handling, transport and installation operations.
