    Abstract: A utility skid tree system for subsea wellheads enables a tree to be mounted by and interface with utility skids. Production bore access is provided through an extended production wing block. The system reacts and transfers installation loads and potential snag loads to the conductor. The tree accepts skids for flow boosting, metering, water-oil separation, etc. A conventional choke may be fitted outboard of the utility insert profile.

    Abstract: A modular tree production tree assembly reduces the weight during transfer of the tree components from a barge to a production rig. The tree assembly includes an upper tree module, a lower tree module, and a choke bridge module. The upper tree module has a tree head, the lower tree module has a guidance system and ties in the flow lines to the in-field infrastructure, and the choke bridge module has the choke and instrumentation bridge to link the three components together. Prior to delivery to the rig, the components of the modular tree assembly may be joined together and tested on shore. Upon arrival at the rig, the components are individually lifted from the barge onto the rig by a crane. After the tree components are on the rig, the modular tree is reassembled and then deployed to the sea floor via the draw works.

    Abstract: An actuator for use with valves in a subsea wellhead assembly. The actuator includes a shaft with an alternating polarity along its length and windings spaced around the shaft that create a magnetic field around the shaft. The shaft is connectable to a valve stem so that flowing current through the windings creates a magnetic field for linearly moving the shaft and operating the valve. A fail safe mechanism can be included that pushes the shaft back to its original position thereby also moving the valve into its original, or fail safe, position.

    Abstract: A subsea production tree has an external annular profile formed on an upper portion of the tree. A vertical passage extending from a lower end of the tree to an upper end of the tree for communicating with a string of tubing extending into the well. A lateral passage in the tree extending from the vertical passage. A flow path in fluid communication with the lateral passage extends laterally from the tree, the flow path having an upward facing receptacle. An adapter lands on the upper portion of the tree and connects to the profile, the adapter having a passage that registers with the vertical passage of the tree while the adapter lands on the tree. A flow interface device mounts to and lands with the adapter, the flow interface device having an inlet conduit and an outlet conduit, one of the conduits being connected to the passage in the adapter, the other of the conduits stabbing into sealing engagement with the receptacle as the adapter lands on the tree.
