Safety contour is the most important safety setting in ECDIS. This setting only responsible in generating an anti-grounding alarm on ECDIS, for the display of unsafe water areas and detecting isolated dangers. The Safety contour setting was primarily designed to …

These incidents illustrate some fundamental aspects of ECDIS chart display that must be understood. There are a small number of settings that need to be

Safety depth: Safety depth is Ship’s draft+Squat. It’s main function is to display spot sounding by highlighting it in bold. Usually it is a practice to keep Safety Depth=Safety Contour. 2014-1-21 · •Depth contours may be 3 –5 –10 –20m in a port where max draft allowed is 14.5m •If the ship sets 13m safety contour in this area the ECDIS will select the next higher safety contour (20m) and the entire sea area will be deemed as non-navigable.

Safety depth and safety contour determination in the ECDIS system are still not established for the wo rld maritime ship-owners fleet . Based on the above, it could be set Condition: 1.b - ECDIS selects a safety contour deeper than the safety contour depth and the safety depth set by the mariner . Display: Some soundings on the shoaler side of the safety contour will be gray, because they are deeper than the safety depth s et by the mariner, but shoaler than the safety contour selected by ECDIS. Did not react though the vessel’s vector on ECDIS was heading directly towards the safety contour. Did not react when Muros crossed the 10m safety contour at approximately 02:18. Did not immediately appreciate that the vessel might have grounded when its speed was reduced to less than one knot at 02:48. accordance with IMO ECDIS Performance Standards and IHO S52 Ed 6.1.1.

electronic and paper format and maritime safety information depth contours and the most important depth quirements of ECDIS being implemented and the. 'The vessel proceeded safely, but with a heavy forward trim, to a port of safe on a course Iying within 20 miles to seaward of the 100 m bathymetric contour. Aerospace Medicine In Aviation Safety.

I can set the ECDIS to automatically choosing a Safety contour based on my setting of ship’s maximum draft. c. I can set Ship’s maximum height to enable chart alerts from areas in the charts where there is not sufficient air draft.

If you enter all these Where there is no appropriate safety contour available on the ENC (the programmed depth contour on the ENC is not equal to the safety contour setting), the safety The safety contour that is available in the chart cell located under the ship's position. → Note: If ECDIS does not find a safety contour equal to the selected value, 8 Nov 2017 This is really unacceptable as a proper setting of the ECDIS must be checked Thevalues for the safety depth and safety contour must be Shows the currently selected chart scale.

SAFETY DEPTH / SAFETY CONTOUR: Safety depth is considered to be the minimum depth required in which the vessel can safely navigate and any depths lower than that might compromise the safety of the vessel. For all practical purposes the safety depth is 2021-4-15 · Now the contour will be set by ECDIS automatically to 15 meters or the next available value. Safety depth: Safety depth is Ship’s draft+Squat. It’s main function is to display spot sounding by highlighting it in bold. Usually it is a practice to keep Safety Depth=Safety Contour. 2014-1-21 · •Depth contours may be 3 –5 –10 –20m in a port where max draft allowed is 14.5m •If the ship sets 13m safety contour in this area the ECDIS will select the next higher safety contour (20m) and the entire sea area will be deemed as non-navigable. •Spot soundings may … 2020-4-2 · The safety contour defines the safe water the vessel can navigate in based on the depth areas and contours included in the ENC; and the safety depth defines isolated dangers that are located in otherwise “safe” water.

Usually it is a practice to keep Safety Depth=Safety Contour. otherwise Safety Contour alarms will be meaningless or so intrusive as to be ignored. It is possible for a vessel to receive no safety contour alarms at all. For example vessels transiting the River Thames would not receive any safety contour alarms with the default 30m safety contour. Some operators might, at first, A number of settings related to the charted depth are applied on the ECDIS: the safety contour, the safety depth and the shallow and deep contours.

Webinar: Mooring Safety - IMO and Industry perspective If we set ECDIS Safety Contour to 17 meters which symbol from the picture will appear on the display?

For example, on a ship with a draught of 8 metres negotiating the Dover Strait with a default setting of 30 metres, the ECDIS would show much of the Straits as unsafe water. ECDIS check-off cards should be checked to ensure that settings of anti-grounding cone, safety depth, safety contour, velocity vector, units, chart priorities and chart auto-load are correct; Check that both Primary and Secondary position sources are selected and that they are working correctly The ECDIS safety depth setting was appropriate for the voyage, but the safety contour value of 5m was not.
