Abstract

The positions and motions of a bow and a stern of the ship are detected using redundant devices and evaluated to automatically perform difficult maneuvers in ports or to generate recommendations for controlling the ship

Claims

1. Method for the computer-supported control of a ship, wherein during berthing maneuvers, positions and motions of the ship as well as moving or stationary obstacles or factors of instability are detected automatically via redundant means, and a screen displaying the actual position of the ship relative to obstacles and factors of instability as well as started or recommended control measures is controlled via a computer.

2. Method according to claim 1, wherein periodic motions of the ship (pitching, skidding, and rolling) are substantially detected via an inertia and/or motion sensor.

3. Method according to claim 1, wherein via the computer, saved data of a model of the ship can be used and wherein its reactions on control interventions and determinable ideal conditions can be detected and compared with actual reactions of the ship in order to quantitatively detect disruptive factors.

4. Method according to claim 1, wherein via a GPS system with one GPS receiver on the bow and one on the stern there can be a check for plausibility or exactitude, by comparing the distance detected from the positions between the positions of bow and stern with a saved value, determined by the design.

5. Method according to claim 1, wherein on the screen, a most probable position of the ship as well as a zone of uncertainty is displayed figuratively.

6. Method according to claim 1, wherein on the screen, it is displayed whether planned or necessary maneuvers can be performed with the available control and drive systems of the ship.

7. Method according to claim 6, wherein via the computer, on the screen are displayed appropriate maneuvers of tug and towing vessels or similar vessels.

8. Method according to claim 1, wherein during manual control of the ship, the computer proposes appropriate operations of the control and drive systems of the ship and displays the actual position as well as a desired position of the ship on the screen.

9. Method according to claim 1, wherein via a minimum of three sensors measuring the distance, attached on measured positions of the ship, obstacles can be detected in a coordinate system on the ship.

10. Method according to claim 9, wherein the motions of the ship are detected by an inertial navigation device as of a starting point when the obstacles were entered into the coordinate system on the ship.

11. Method according to claim 9, wherein motions of the ship are detected via redundant sensors, e.g. a compass or GPS system or inertia sensors.
