  • Patent number: 11149544
    Abstract: A technique facilitates communication in a subsea well application. The technique involves deployment of a blowout preventer subsea control and telemetry system to a subsea location proximate a wellbore. The blowout preventer subsea control and telemetry system is coupled to both a blowout preventer system and a wireless telemetry system. The wireless telemetry system has a plurality of repeaters deployed along the wellbore. The blowout preventer subsea control and telemetry system is used both to collect data from the wireless telemetry system and to control operation of the blowout preventer system. For example, the blowout preventer subsea control and telemetry system may receive control signals from a surface system and also relay data to the surface system through a common communication line.

    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.

  • Publication number: 20150129236
    Abstract: An offshore well system for a subsea well. The system includes a floating platform, an external riser and an internal riser nested within the external riser. A external riser tension device tensions the external riser. The drilling system also includes a surface wellhead system that includes a wellhead, a collet, and a flange assembly. The wellhead, collet, and flange assembly are assembled to establish a common bore for receiving the top of the internal riser. A gasket located between the top of the internal riser and an inner shoulder of the flange assembly seals between the wellhead system and the top of the internal riser. The surface wellhead system also retains the internal riser in tension with the wellhead, the internal riser extending above the wellhead into the collet.

  • Patent number: 9010436
    Abstract: A tensioner assembly for applying tension to a tubular member, such as a riser, can include an upper latch connected to the tubular member, a platform with a bore, and a lower latch ring. After applying tension to the tubular member, the lower latch ring can be closed around the tubular member so that when the tension is released, the upper latch lands on and engages the lower latch. The assembly can include a locking mechanism that prevents axial movement of the upper latch, relative to the lower latch, after engagement. The upper latch can self-center on the lower latch as it is moved into the latching position.

  • Patent number: 8997874
    Abstract: A method of evacuating hydrocarbons from a plurality of nested tubulars of a well pipe, extending from an underwater well tree, includes attaching a fluid transmission line to the underwater well tree, the fluid transmission line having one end portion forming the attachment to the tree and the other end portion attached to a pump that forces fluid under pressure to the tree and attached nested tubulars. Openings are formed through one or more tubulars at a selected location. A specially configured fitting is attached to the tubulars. The fitting seals the openings. The fitting has an expandable seal that is expandable responsive to rotation of a rotating member that rotates upon a saddle, pulling a tapered mandrel against the seal. The saddle surrounds the mandrel and bears against an outer tubular of the nested tubulars. The fitting mandrel has a bore through which hydrocarbons escape from the tubulars.
