The female connector can be adapted for connection with the male connector, wherein engagement between the male connector and female connector communicates the axial bore of the male connector with a bore of the female connector to define a flowpath for communicating a medium. The systems and methods enable the ability to connect or disconnect well equipment remotely without the need of a diver, an ROV, and without the need to bring the well equipment to the surface for disassembly.

  • Patent number: 9033051
    Abstract: A system for the diversion of flow from a wellhead has a mudline closure mechanism suitable for attachment to the wellhead, a blowout preventer connected or interconnected to the mudline control mechanism, and a flow control line having one end connected to a diversion passageway of the mudline control mechanism and extending therefrom such that an opposite end of the flow control line is disposed away from the mudline closure mechanism. The mudline closure mechanism has a main passageway communicating with the flow passageway of the blowout preventer. The mudline closure mechanism has a valve suitable for switching fluid flow from the main passageway to the diversion passageway. The blowout preventer is positioned above the mudline closure mechanism. The flow control line is supported by a base anchored into the subsea floor away from the mudline closure mechanism.

    Abstract: An apparatus and method for controlling fluid flow in a blowout preventer. In one embodiment, an apparatus for connecting fluid lines includes a socket fluid connector and a plug fluid connector. Each connector includes a flow channel. The plug fluid connector is detachably connectable to the socket fluid connector at a connection end of the plug and socket fluid connectors such that the flow channels align. Each of the socket and plug fluid connectors includes a check valve in the flow channel. The check valve is configured to prevent fluid flow through the connector flow channels while the plug and socket fluid connectors are not connected, and to enable bidirectional fluid flow through the connector flow channels while plug and socket fluid connectors are connected.

    Abstract: A riser section for joining to another riser section to form a drilling riser includes a weld region generated by welding a first riser tube to a second riser tube. The weld region includes a fusion zone in which material of the first riser tube coalesces with material of the second riser tube, and a heat-affected zone adjacent the fusion zone. The riser section also includes a cover positioned over the weld region and welded to the first riser tube and to the second riser tube such that the cover covers the fusion zone and the heat-affected zone to protect the zones. The cover may be a solid piece of material that is welded to the riser tubes, or the cover may be a bead of weld filler material that is welded (melted and deposited) onto the weld region of each of the riser tubes.

    Abstract: The invention provides a flow control valve for a subsea hydrocarbon production system and a method of use. The flow control valve comprises an inlet configured to be in fluid communication to an injection fluid conduit and an outlet configured to be in fluid communication with a subsea flow system. A flow control mechanism is disposed in a flow path between the inlet and the outlet and is arranged to adjust a flow rate through the flow path. The flow control mechanism is configured to automatically adjust the flow rate of injection fluid through the flow path according to a pressure differential between fluid pressure at the inlet and fluid pressure at the outlet. Adjustment may be self-regulating, or may be controlled by a hydraulic control circuit.
