An underwater vehicle control system includes at least one controller configured to receive a control input signal indicative of a target virtual position and/or a target virtual orientation of a target virtual underwater vehicle within a virtual environment. The at least one controller is also configured to output a target virtual underwater vehicle signal to a display indicative of instructions to display a visual representation of the target virtual underwater vehicle at the target virtual position and/or the target virtual orientation within the virtual environment. Furthermore, the at least one controller is configured to output a target physical underwater vehicle signal to an underwater vehicle within a physical environment indicative of instructions to move the underwater vehicle to a target physical position and/or a target physical orientation within the physical environment corresponding to the target virtual position and/or the target virtual orientation of the target virtual underwater vehicle.
G05D 1/00 - Control of position, course, altitude or attitude of land, water, air or space vehicles, e.g. using automatic pilots
G05D 1/02 - Control of position or course in two dimensions
G06F 3/0484 - Interaction techniques based on graphical user interfaces [GUI] for the control of specific functions or operations, e.g. selecting or manipulating an object, an image or a displayed text element, setting a parameter value or selecting a range
G06F 3/0481 - Interaction techniques based on graphical user interfaces [GUI] based on specific properties of the displayed interaction object or a metaphor-based environment, e.g. interaction with desktop elements like windows or icons, or assisted by a cursor's changing behaviour or appearance
G06T 19/00 - Manipulating 3D models or images for computer graphics
A subsea umbilical termination assembly comprising a base (1), said base (1) includes a core frame construction (2) with elongated sides (3, 4) onto which support plates (5, 6, 7) are mounted, wherein at least a pair of mounting rails (12, 13) are respectively secured to the core frame construction (2) along elongated sides (3, 4) and said mounting rails (12, 13) are provided with positioning elements (16, 17) to allow a modular support plate arrangement, which is fixed to the mounting rails (12, 13).
An apparatus includes a flowline connector having an inboard pipe and an outboard assembly. The outboard assembly includes a frame and an outboard pipe moveable within the frame to allow the outboard pipe to be moved toward the inboard pipe. The outboard assembly also includes a profile pipe in which the outboard pipe is received, and the profile pipe and the outboard pipe are connected to move together. The profile pipe includes at least one guide to change pitch or yaw of the outboard pipe to direct the outboard pipe toward alignment with the inboard pipe as the outboard pipe is moved within the frame toward the inboard pipe. Additional systems, devices, and methods are also disclosed.
E21B 41/00 - Equipment or details not covered by groups
E21B 43/01 - Methods or apparatus for obtaining oil, gas, water, soluble or meltable materials or a slurry of minerals from wells specially adapted for obtaining from underwater installations
F16L 1/26 - Repairing or joining pipes on or under water
