The Okeanos Explorer has two large rudders that steer the ship while underway. These rudders turn together in the same direction and are controlled by two steering pumps. The steering pumps receive input from the bridge through a controller and turn the rudders accordingly. The controller unit received calibration to ensure that the proper rudder angle is used.
