Japan NIESS Navigational Intension Exchange Support System (Passing Pattern) Link to Seperate Page
Function:
Display of collision threat areas as a Radar overlay on scheduled route.
Example:
Advantage:
Visualize collision danger area. From a portrayal point of view similar to the Sperry introduced PAD.
Disadvantage:
Too much information on the Radar. Radar display limits the ability of displaying additional data. It clutters the Radar, especially if larger or overlapping danger areas are to be displayed. It is difficult to link danger area to target ship in the portrayal.
Recommendation:
It may be beneficial to add data layers on Radar, but this need to be limited and data needs to be carefully selected.

Example:
Advantage:
Clear visible target information. Enhances visual look-out. Linking real world and digital information.
Disadvantage:
Display may be confusing if too many information is shown. Possible cluttering of outlook.
Recommendation:
Level of details need to be controlled. Environmental conditions (e.g. light) needs to be considered.

Example:
Advantage:
Link digital and visual information. Include future trajectory of target ships and collision danger area. Reduced cluttering by split display. Possibility to use enhanced night vision.
Disadvantage:
Limited use for collision avoidance and planned route. Needs cognitive analysis on the effect of using two split screens simultaneously.
Recommendation:
Additional display may be recommended. Stabilization of video image is necessary.

Japan Collision Avoidance Display for automatic collision avoidance system (recommended collision avoidance route) Link to Seperate Page
Function:
Provide recommended collision avoidance route on ECDIS.
Example:
Advantage:
Renders alternatives as an advice for navigation. Displayed on the primary navigation tool. Easy to understand and includes track control portrayal. Takes in account navigational significant object.
Disadvantage:
Potential of “overcrowding” the primary navigation display. Potential for distraction of navigator due to focus of display on collision avoidance. Difficult to communicate new route to potential target ships in condensed areas.
Recommendation:
Use of different color for scheduled, recommended and accepted (for tracking) route. Ensure recommended route does not overlay important information (e.g. transparency)

Korea NAVIEYE Vessel surveillance equipment (Video image of target ship) Link to Seperate Page
Function:
Show target vessel on electronic chart with video image in day and night.
Example:
Advantage:
Video image is directly linked to tracked ship by NAVIEYE. Show video image of tracked target in day and night
Disadvantage:
The video image covers ENC data. It is difficult to link the image and tracked target symbol
Recommendation:
Ensure video images do not overlay important information. Stabilization of video image is necessary.

Function:
Suggest optimal navigational speed. Display marine engine information. Lower CO2 emission by reducing oil consumption
Example:
Advantage:
Well organized for easy understanding of meaning of the data.
Disadvantage:
Do not use red for optimized value display. Do not display too much information on one display.
Recommendation:
Use intuitive color to portrayal information. Do not display too much information on one display. Use much larger font.

EfficienSea METOC Metrological and Oceanographic Data Link to Seperate Page
Function:
Visual Presentation of Predicted Metrological and oceanographic data in the Chart display. Prediction is based on current speed and the planned schedule.
Example:
Advantage:
Intuitive presentation used for Wind. Quick and easy to understandable information on the predicted prerequisites along the planned route
Disadvantage:
Not intuitive indicator for wave and current. Current vector to large
Recommendation: Gap Reference: User Need Reference:  
EfficienSea Route Suggestion Route suggestion from Shore to Ship Link to Seperate Page
Function:
Possible to transfer route with up to 15 route segments including start and end time. AIS capacity limits the number of WP
Example: Advantage:
The transferred route gives an exact presentation of the recommended route and can be used for planning onboard the vessel.
Disadvantage:
The transferred route cannot be used for monitoring as a number of parameters such as Turn radius, XTE are not included in the data exchange. Routes have not been checked for monitoring or Track Control.
Recommendation:
Drawbacks can be eliminated if the exchange protocol is modified or other means of communication is used as part of eNav

EfficienSea Intended Route Route broadcast from Ship to Ship Link to Seperate Page
Function:
Ship broadcasts its intended route (the next say 8 waypoints of its voyage plan, limited by AIS) to all nearby ships
Example: Advantage:
The broadcasted routes gives better awarenes for the surrounding ships and nearby VTS centers.
Disadvantage:
The broadcasted route cannot be used for monitoring as a number of parameters such as Turn radius, XTE are not included in the data exchange. Routes have not been checked for monitoring or Track Control.

EfficienSea AIS+ WI Weather information Link to Seperate Page
Function:
Displays ships position plus current and historical weather on separate chart display.
Example:
Advantage:
Graphic display both as symbol, a standard wind barb and alphanumerical data direct in a chart gives the mariner real time wind speed and direction directly linked to a geographical position. History fluctuation is easily spotted in a time series graph. User defined settings possible.
Disadvantage:
You still need to look at devise not integrated in the bridge equipment. Or, if integrated, in i.e. ECDIS, when displaying the notice area other vital chart information might get cluttered.
Recommendation:
Some real time information could be integrated in ECDIS to be shown on demand but more comprehensive information is better displayed on another screen.

EfficienSea AIS+ AN Area Notice Link to Seperate Page
Function:
Displays ships position plus a geographic area and additional selectable written information on a separate chart display.
Example:
Advantage:
Geographical position and notice area limits in relation to ships position are easily identified. Information expands when clicking the notice area.
Disadvantage:
You still need to look at devise not integrated in the bridge equipment. Or, if integrated, in i.e. ECDIS, when displaying the notice area other vital chart information might get cluttered.
Recommendation:
The area notice would benefit from more integration. But doing so graphic overload in i.e an ENC is a risk. Integrating with existing ENC symbology is desired.
