  • Patent number: 12330865
    Abstract: A portable bag hanging apparatus may easily and securely attach to a wider variety of objects and enables more diverse use cases. The bag hanging apparatus includes a catch end and attachment end connected by first and second connectors made of soft, crushable, and collapsible material. The connectors may be secured between two objects with an interference fit while the catch end provides additional retention. Alternatively, the connectors may be wedged between two objects with something less than an interference fit, relying instead on the catch end to secure it in place. All exposed portions of the portable bag hanging apparatus are composed of soft material that is quiet when it comes into contact with other objects. In addition, the portable bag hanging apparatus is small, foldable, and virtually indestructible such that it may be easily stored and transported without risk of damaging it during travel.

  • Patent number: 10865608
    Abstract: A mobile offshore drilling unit is converted to provide drilling, completion and workover access to multiple dry tree wells from a drilling derrick to allow production and export of oil and gas from high pressure, high temperature reservoirs in deep offshore waters. Existing practice has been for the drilling derrick on a production platform supporting dry tree wells to be moved over a fixed well slot. The present invention provides a movable wellbay that supports multiple top-tensioned subsea well tieback risers, which may be positioned directly below the derrick's rotary table and/or beneath another operating device. The use of top-tensioned subsea well tieback risers supported by the movable wellbay allows the converted facility to drill, complete, maintain, improve and produce from subsea wells through dry trees.
