Publication number: 20190193817Abstract: A natural gas liquefaction vessel including an increased deadweight tonnage, as compared to a liquefied natural gas carrier (LNGC) of a comparably-sized ship, is achieved by reducing the LNGC's cargo capacity. This difference creates room on the port and starboard sides of cargo tanks to increase the size of the adjacent wing tanks. The increased size of the wing tanks occupy the space created by the reduced cargo tank size of the vessel and may support a larger upper trunk deck. The ballast wing tanks and smaller cargo tanks increase the deadweight available. With this approach, the larger upper trunk deck of the vessel is able to support an efficient floating liquefaction plant that improves the LNG value chain because it is capable of producing 2.0-3.0 MTPA in the footprint of a standard vessel hull, such as for example a Q-Max hull.Type: ApplicationFiled: January 12, 2017Publication date: June 27, 2019Inventors: Michael Todd Carroll, Graeme David Trotter, Trevor Earl Wilkinson, Kenneth Hugh McGeachie

Publication number: 20190193855Abstract: Example implementations may relate to door-enabled loading and release of payloads in an unmanned aerial vehicle (UAV), which could be a type of UAV in a group of UAVs that is assigned to carry out certain transport tasks. In particular, the UAV may include a fuselage having a first side and a second side, as well as a chamber formed within the fuselage and arranged to house a payload. A first door may be arranged on the first side of the fuselage, such that an opening of the first door enables loading of the payload into the chamber. And a second door may be arranged on the second side of the fuselage, such that an opening of the second door enables release of the payload from the chamber. Moreover, the UAV may include a control system configured to control flight of the UAV, and possibly opening and/or closing of door(s).Type: ApplicationFiled: December 21, 2017Publication date: June 27, 2019Inventors: Andre Prager, Adam Woodworth

Publication number: 20190193856Abstract: An example system includes an aerial vehicle, a sensor, and a winch system. The winch system includes a tether disposed on a spool, a motor operable to apply a torque to the tether, and a payload coupling apparatus coupled to the tether and configured to mechanically couple to a payload. The system also includes a repositioning apparatus configured to reposition the payload coupling apparatus in at least a horizontal direction. A control system is configured to control the aerial vehicle to deploy the payload coupling apparatus by unwinding the tether from the spool; receive, while the aerial vehicle hovers above the payload and from the sensor, data indicative of a position of the payload coupling apparatus in relation to the payload; and reposition, using the repositioning apparatus and based on the data, the payload coupling apparatus in the horizontal direction to mechanically couple to the payload.Type: ApplicationFiled: December 21, 2017Publication date: June 27, 2019Inventors: Andre Prager, Trevor Shannon, Adam Woodworth

Publication number: 20190193859Abstract: In one embodiment, a dual configuration aircraft lavatory includes a plurality of walls enclosing and defining a lavatory interior space, wherein one of the walls is coextensive with a portion of the cabin. Within the lavatory interior space are a toilet, a washing station and a waste receptacle movable between a first position and a second position. In the first position, the waste receptacle is attached to a wall of the lavatory between the washing station and a door wall. In the second position, the waste receptacle occupies a second predetermined volume of space in the aircraft cabin separated from a first predetermined volume of space occupied by the waste receptacle in the first position. Moving the waste receptacle from the first position to the second position reveals additional space within the lavatory sufficient so that two adult humans simultaneously fit within the lavatory interior space.Type: ApplicationFiled: December 11, 2018Publication date: June 27, 2019Applicant: Airbus Operations GmbHInventors: René Waldheuer, Andreas Heidtmann
