  • Patent number: 8893801
    Abstract: A method is presented for connecting and disconnecting sections of a work string for use in a subterranean wellbore. A preferred method of disconnecting includes the steps of positioning a stinger and a downhole tool assembly of a work string adjacent upper and lower sealing rams, such as in a BOP and lubricator assembly. The sealing rams are closed, defining a first and second pressure zone adjacent the tool. A differential pressure is applied across the pressure zones, moving a piston element in the tool assembly. Axial movement of the piston element causes relative rotational movement of cooperating locking elements. In one embodiment, the locking elements are rotated to an unlocked position and then move relative to one another axially in response to a biasing spring. The relative axial movement of the locking elements results in unlatching of a latching assembly, thereby disconnecting the tool and stinger.

  • Patent number: 8720574
    Abstract: A subsea connector that includes a connector capable of selectively connecting to a spool body to form a connector assembly. The subsea connector may include an adapter ring that is capable of connecting the spool body to the connector. The connector assembly may be lowered onto a wellhead member and locked into place by a movable piston and split lock ring. While the connector assembly is in the unlocked state, the adapter ring may be rotated moving the connector up or down with respect to the spool body, which lands on the wellhead member. The movement of the connector may be used to vary the alignment of the connector locking means with respect to the locking profile of the wellhead member. This change in position may be used to modify the preload force applied to the connector when locked onto the wellhead member.

  • Patent number: 8672038
    Abstract: A retrievable bridge is provided which mounts to the top of a subsea tree to provide fluid communication between the production line of the subsea tree and a production flowline. The retrievable bridge mounts to the top of the subsea tree and preferably connects to a vertically oriented pipe of the production flowline. The retrievable bridge can be utilized to carry wear items such as chokes, subsea control modules, and flow meters which may require maintenance more often than other components of the subsea tree. By mounting these items along the flow passageway in the retrievable bridge the components are securely mounted and still available for maintenance/replacement without the need to remove the entire tree. In one embodiment, Intervention into the well is available without removing the retrievable bridge.

  • Patent number: 8672037
    Abstract: A method for removing a plug from and setting a plug into a subsea installation is provided. The method for removing the plug includes the steps of deploying an intervention package having at least one valve, pipe rams, and a lubricator into a subsea environment and latching the intervention package to the subsea installation. The method further includes lowering a stroking tool into the intervention package by conveyance from a surface facility, and grabbing the stroking tool with the pipe rams that form a part of the intervention package. Once the stroking tool is held by the pipe rams, the method further includes activating the stroking tool to stroke in an upwards or downwards direction to remove the plug positioned in the subsea installation. Once the plug has been removed by the stroking tool, the method further includes pulling the stroking tool out of the intervention package and retrieving the stroking tool and plug at surface.

    Abstract: The tool includes a bearing member (70), a traction assembly (72) of the object (28), movably mounted in a first direction relative to the bearing member (70). It includes a plurality of hooking members (160), mounted radially mobile relative to the traction assembly (72) between a contracted configuration and a deployed configuration. The tool comprises means (164; 166) for keeping each hooking member (160) in its deployed configuration. It includes unlocking means (168; 170) that include an elastic stressing member (202; 222) applied on the holding means (164; 166). The elastic stressing member (202; 222) is capable of being compressed to cause the unlocking of the holding means (164; 166) and the passage of the hooking members (160) from their deployed configuration to their contracted configuration.

    Abstract: The disclosure is directed to a method for retrieving a drilling riser connected to a blow-out-preventer (BOP) located on a sea bed. The method includes the steps of: a) attaching the first end of the retrieval line to a vessel; b) attaching the second end of the retrieval line to a drilling riser; c) disconnecting the riser from the BOP; d) initiating the assent of the disconnected riser from the sea bed; e) maintaining tension on the riser as it ascends to the sea surface by creating a horizontal load that is opposite to a current load on a bottom end of the riser; f) releasing tension on the retrieval line as the riser approaches the bottom of the drilling vessel; and/or g) disconnecting the retrieval line from the riser, whereby the riser is pulled through the bottom opening in the drilling vessel.
