🤿 Deep-Sea ROV: Tether Drag, Thruster Power and Holding Station in a Current (2D)

Side view of a remotely operated vehicle hanging on a straight tether below a ship, with a sideways water current. Set the depth, the tether angle and thickness, the current, the size and drag of the vehicle, the number and size of the thrusters and the electric power, and see the drag forces, the thrust and power needed to hold position and the strongest current the vehicle can resist. Thruster momentum, tether drag integral, the holding limit and the transit speed are checked with four in-page numerical checks.
