Be in Command by Knowing These ECDIS Safety Settings
to the Route, Safety Depth, Safety Contour, Alarms and Displayed Data. A ship can ground just as easily as a consequence of improper configuration as it could from sloppy chartwork on a paper chart. Where the ECDIS in use supports it, display configurations should be saved so that the system can be set up quickly when transiting between different environments such as Confined Waters, Anchoring... Da Gama recommends ecdis alerts should be set up correctly to reduce alarm fatigue on the bridge. The safety contour is the most important alert to set up correctly. “The safety contour needs to be of greater value than the draft of your vessel, but low enough to provide safe water to …

What does the default safety contour default in ECDIS? 30 metres If you've selected a safety contour, and that contour is not available for that area of chart, to what value will it default?... contour line equal to the safety contour depth value set by the mariner, then ECDIS sets the next deeper contour as the safety contour. Depending on the contour intervals used on

How To Set Safety Contour On Ecdis
Safety contour: (valid only for manual updates- not for ARCS) User can set value of safety contour. Visible safety contour is equal to set value or if the contour of set value is not available then the visible safety contour is next deeper contour than safety contour,. Note, the system uses Safety contour also for Chart Alarms.
- Information on the majority of ECDIS operations and techniques is included, such as chart updates, route creation and checking and ECDIS safety functions. This is supplemented by a useful ECDIS Management Card and example logs for chart spot checks, manual corrections and chart updates.
- Safety Contour marks the boundary between safe and unsafe water. Safety depth affects the display of soundings. Here 7m or less appear in black 7 . Dredged area less than safety contour value . Dredged to 9.5m . Dredged area less than safety contour . The depth contours may differ between electronic charts produced by different hydrographic offices. 10.9 m . 5.4 m . 18.2 m . Example: US Charts
- Performance standards for electronic charts were adopted in 1995, by resolution A.817(19)), which was amended in 1996 by resolution MSC.64 (67) to reflect back-up arrangements in case of ECDIS failure.
- Safety contour in use When using ECDIS for voyage planning, the navigation officer should establish a “safety contour” around the vessel to fully use the automated function of ECDIS. The safety contour function of the ECDIS allows the mariner to choose a depth contour (isobath) from the database to be emphasized and associated with a variety of available alarms. If the ship crosses a
