AIS Route Display for Monitoring Ship Navigation Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to effectively monitor and ensure compliance with navigation instructions from control centers by other ships in a maritime environment.
Innovation Solution
A ship navigation support system and method that utilizes a control center to generate and distribute recommended routes and acknowledgment data via AIS, allowing ships to visually distinguish between compliant and non-compliant vessels through discriminable route displays on electronic nautical charts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If recommended routes and acknowledgment data are distributed via AIS, then the ability to monitor ship movements is improved, but the complexity of the navigation support system increases
Solution Approach 1:
The patent uses AIS (Automatic Identification System) as an intermediary communication medium to distribute recommended routes and acknowledgment data between control centers and ships. This leverages an existing maritime communication infrastructure to achieve monitoring without building a completely new system, thus improving reliability while managing complexity through selective use of available technology
Solution Approach 2:
The navigation support device performs multiple functions: receiving recommended routes from control centers, displaying them on electronic nautical charts, receiving acknowledgment data from ships, and determining compliance. By consolidating these functions into a single multi-functional device, the system improves monitoring capability while avoiding the complexity of multiple separate systems
2Ease of operation
If ships display recommended routes on electronic nautical charts, then the ease of grasping ship movements is improved, but the loss of information increases
Solution Approach 1:
The patent applies different display characteristics to different elements on the electronic nautical chart: recommended routes are displayed with specific visual attributes (such as different line styles or colors) compared to actual ship positions and other maritime information. This local differentiation allows ships to be easily distinguished by compliance status while preserving the integrity and visibility of other critical navigation information
Solution Approach 2:
The system uses color coding or visual attribute changes on the electronic nautical chart to indicate whether a ship is compliant with recommended routes. For example, compliant ships might be displayed in one color while non-compliant ships are highlighted in another color, making compliance status immediately visible without obscuring other chart information

AI summary
The present disclosure provides a ship navigation support system capable of easily grasping a movement of a ship. The ship navigation support system includes a recommended route providing device that transmits recommended route data for a first ship, a first ship navigation support device that is mounted on the first ship and transmits acknowledgment data indicating that a recommended route based on the recommended route data for the first ship has been approved, and a second ship navigation support device that is mounted on a second ship and includes a recommended route acquiring module that acquires the recommended route data for the first ship, an acknowledgment acquiring module that acquires the acknowledgment data, and a display unit that displays the recommended route based on the recommended route data for the first ship so as to be discriminable before and after the acquisition of the acknowledgment data.
