  • Publication number: 20140349517
    Abstract: A radially uniform spring-biased intra-pole plug connector and transformer outside the trunk configuration for an electric artificial tree is described. The radially uniform plug comprises a springed-tip and a prong, and allows the tree trunk segments to be connected at any point along their 360 degree circumference. The plug connector resembles the structure of a car cigarette lighter. A mold is used to sandwich the plug within the trunk. A plug portion of the plug connector is housed in one trunk segment, and a receptacle portion is housed in a different trunk segment, such that when the trunk segments are assembled, the plug is connected, illuminating the tree. The plug allows the electrical wiring to be hidden and housed within the trunk, providing safety, convenience to the user and giving the tree a cleaner appearance. The transformer outside the trunk configuration makes the trunk safer, more lightweight and less bulky.

  • Publication number: 20090038804
    Abstract: An all electric subsea tree can be coupled with a hydraulic pressure unit that is fed off electrical and control lines that are in the umbilical from the surface. In that way hydraulic lines do not need to be separately run from the surface to the tree. Alternatively hydraulic pressure can be generated at a downhole tool using power and control lines running from the tree to the downhole equipment. As another alternative, the downhole equipment can be run by electric motor located downhole adjacent the downhole equipment and powered and controlled by lines running from the tree to the downhole location.

    Abstract: Various embodiments include modeling a component fault tree for a circuit with an input-side and an output-side component. These include using a fault tree corresponding to a hazard for each respective component, obtaining information about the components of the circuit and a connection between components, and connecting the respective fault trees based on the circuit description. Each fault tree includes an input fault mode or a basic event and an output fault mode. The output fault mode and the input fault mode are each assigned to a component terminal. An output fault mode of the input-side component tree is connected to an input fault mode of the output-side component tree if: there is a connection between the assigned terminal of the input-side component and the output-side component and the output fault mode of the input-side component correlates to an input fault mode of the output-side component.
