– Reduces the number of alarms raised as a result of ECDIS safety checking. Detecting the Safety Contour: – The IMO ECDIS Performance Standard (PS) states

a depth area, whose colour fill depends on the choice of the safety contour. som ska ändras eller införas i ett ECDIS för inlandssjöfart, utöver de metoder för

For this reason, we are required to define the procedure we would follow after crossing the safety contour to ensure that ship navigates safely. There are two methods to choose from. ECDIS Safety Contour Exerters Training Centre - YouTube. ECDIS should emphasize the safety contour over other contours on the display, however: if the mariner does not specify a safety contour, this should default to 30m. If the safety contour specified by the mariner or the default 30 m contour is not in the displayed SENC, the safety contour shown should default to the next deeper contour; If playback doesn't begin shortly, try restarting your device. Videos you watch may be added to the TV's watch history and influence TV recommendations. To avoid this, cancel and sign in to Safety Frame or Safety Cone is equally as important as the Safety Contour, as this will provide an early indication of the vessel running into danger or approaching an area of concern.

The safety contour provides a visible boundary between "safe" and "unsafe" water with respect to depth, and is highlighted on the display to enable easy identification. ECDIS safety settings must be configured correctly to ensure sufficient UKC, to ensure correct interpretation of the ENC and to ensure that charted objects on the ENC are properly identified by the ECDIS as dangers or hazards to navigation. The essential ECDIS safety settings to understand include: Display Settings. Safety Contour. Safety Depth The safety depth should be used while planning the passage and a safety guard zone used for monitoring the passage. Contour setting: A safety contour is intended to show the navigator a distinction between safe and unsafe water.

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. The safety contour could have been set at a higher minimum value of 7.5m and the ECDIS would have defaulted to the next deeper ENC contour of 10m. Such a safety contour would have given the impression that the passage was impassable.

2020-2-14 · Navigating Across Safety Contour ECDIS - Safety settings • If the safety contour selected is not available in ENC, it would default to the next available deeper contour. • Result - artificially displaying a reduce amount of safe water on chart. • Action - entire area inside the safety contour cannot be

Контур безопасности в основном представляет The safety contour is highlighted on the ECDIS task screen with a bold line. Safety Contour parameter cannot be larger than Safety Depth parameter. If, however, the operator sets a larger value, the same value is automatically assigned to Safety Depth parameter. And the other way round, if an operator sets The safety contour function on the vessel's ECDIS was fitted with a watch vector function whereby time and angle for the predicted movement of the vessel needed to be set to trigger the safety contour alarm. Although the safety contour had been set at 30m, the alarm did not function as the watch vector had not been activated by the bridge team. ECDIS should be designed following ergonomic principles for user-friendly operation. The largest scale data available in the SENC for the area given shall always be used by the ECDIS for all alarms or indications of crossing the ship’s safety contour and of entering a prohibited area, and for alarms and indications.

The booklet provides a deep insight to clarify the principal ECDIS safety settings and provides guidance to ensure they are understood by the ECDIS operator to maintain safe navigation.

Safety contour may be set equal to but not lower than the safety depth setting. 2021-4-15 · Safety Contour: Is calculated same as per Safety depth AND activates ALARM when depth is less Deep Contour: Indicates the limit of sea area where shallow water effects occur that can affect a vessel. It should be estimated twice or four times … 2020-11-6 · 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.

Once this alarm is muted and ignored, there is no more alarm to warn OOW regarding inadequate depth. Hence, it is important to set the depth alarm in such a way that when Safety contour alarm sounds, OOW takes it seriously and knows it’s time to act. Differentiating the safety settings on ECDIS Shallow contour: 9 meters Safety depth: 14 meters Safety Contour: 15 meters Deep Contour: 50 meters Safety Contour: Is calculated same as per Safety depth AND activates ALARM when depth is less Deep Contour: Indicates the limit of sea area where shallow water effects occur that can affect a vessel. It should be estimated twice or four times the draught of vessel (depending on the depth of water available) HOW TO SET ECDIS SAFETY PARAMETERS = SAFETY DEPTH + SHALLOW CONTOUR - Abhishek Sabharwal.

The greatest single danger from ECDIS is to assume that it has been correctly configured with regard to the Route, Safety Depth, Safety Contour, Alarms and Depths at least as shallow as the safety depth are black; deeper soundings are grey. If Red Safety Contour and Depths is on, then red is used instead of black. ECDIS is capable of operating with both Raster Navigational Charts (RNC) and Electronic LIKELY.

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.

The OOW must understand the values for the safety depth, safety contour and set them properly to achieve a sensible and well thought‐out implication. 2013-2-21 · • Safety Contour Depth: Value set by the mariner that is used by ECDIS to select a “Safety Contour” from among the depth contours available in the SENC that is equal to or deeper than the value.

When this option is selected, following will happen.

temporary change of Safety contour setting) and confirm that audible signal is available for new (unacknowledged) alarms and warnings Yes No 7. ECDIS mandatory connections to navigational sensors Confirm that the main ECDIS is interfaced and receives valid data from: Electronic position fixing system (EPFS) Yes No some issues with ECDIS and ENC's that require workarounds. • Below some Safety contour and safety depth are set equal to safe draft and No-Go Areas are. ECDIS, isolated hazards can be presented on the screen in the form of a red border with a transparent X in the center, but only if the user activates the The ECDIS safety depth setting was appropriate for the voyage, but the safety contour value of 5m was not. The safety contour could have been set at a higher GPS positions should be cross-referenced using visual/ radar range and bearings. Safety contour and safety depth settings can drastically affect the display and It includes worked examples to illustrate best practice and topics covered include: Safety depth and safety contour; display settings; isolated dangers; squat; tidal Safety Depth & Safety Contour In ECDIS. a) Requirement-and-significance-of-bill -of-lading-clauses b) Difference Between towage & salvage c) Manning of Ships d These incidents illustrate some fundamental aspects of ECDIS chart display that must be understood.
