Ship Berthing Control Display for Automatic Pilot Start Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ship berthing control techniques cannot initiate berthing operations until a ship enters a predetermined water area, and operators lack visibility into the specific water area where berthing control can be performed.
Innovation Solution
A control device mounted on a ship, equipped with a control unit that sets and displays a first water area where automatic berthing pilot can start when a berthing location is selected, along with map information. The device also detects obstacles and adjusts the water area accordingly, displaying the adjusted area on a screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic pilot for berthing is used, then berthing operation automation is improved, but the operator cannot grasp the water area where berthing control can be performed
Solution Approach 1:
The patent creates a visual copy of the water area where automatic pilot can operate by displaying it on the display unit. The control device generates and shows a graphical representation (first water area) that corresponds to the actual operational area, allowing the operator to see where the automatic pilot can function without leaving the bridge.
Solution Approach 2:
The display unit acts as an intermediary between the automatic pilot system and the operator. It translates the abstract operational parameters into a visual representation of the water area, mediating the information gap between the automated system's capabilities and the operator's need for spatial awareness.
2Reliability
If berthing control is restricted to a predetermined water area, then safety is improved, but the operator cannot determine where to position the ship for berthing
Solution Approach 1:
The control device performs preliminary calculation and display of the first water area before the ship actually enters it. By showing the operational area in advance on the display unit, the operator can plan the approach and positioning maneuvers beforehand, making it easier to understand where to position the ship while maintaining safety constraints.
Solution Approach 2:
The patent transforms the three-dimensional water area constraint into a two-dimensional visual representation on the display screen. This dimensional transformation allows the operator to perceive the spatial boundaries and safe zones more intuitively, combining safety restrictions with operational clarity.

AI summary
A control device mounted on a ship includes a control unit. The control unit is configured to set a first water area in which automatic pilot for berthing the ship at a berthing location for the ship is able to start when the berthing location is selected. The control unit is configured to display the berthing location and the first water area on a display screen provided in the ship together with map information.
