their depth is less than the vessel safety depth set in the ECDIS. This is due to the specific manner in which these particular shoal. soundings have been

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. ECDIS will select safety contours based on a safety contour depth value set by the mariner. Most charts covering approaches will contain depth contours at intervals of 2, 5, 10, 15, 20 and 30 metres, so ECDIS will sometimes have to set a safety contour at a deeper interval than the value set by the mariner. 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. 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. Most ECDIS systems are designed for the safety contour to default to 30 metres.

2021-4-17 · Safety Contour: A specific depth contour set by ECDIS. It demarks the boundary between “safe-water” and shallow water with an extra wide isoline and is used to give an alarm if the ship, within a time specified by the mariner, is going to cross the safety contour. It is also used to determine the tints used for depth areas and for other purposes.

HOW TO SET ECDIS SAFETY PARAMETERS = SAFETY DEPTH + SHALLOW CONTOUR - Abhishek Sabharwal. 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 determined as follows;

when the ship will cross the safety contour 2. When the specified cross track limit from the planned route is exceeded 3. Other panels THER PANELS AFETY CONTOUR PANEL When vector charts are in use ECDIS displays in the Safety contour panel two values of the depth: The user selected value for safety contour. • The safety contour available in the chart cell located under the ship’s position.

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 Isolated Danger Symbol is displayed if any underwater feature like wrecks, rocks or other obstructions has a depth less than the safety contour in waters beyond the safety contour.

Contour setting: A safety contour is intended to show the navigator a distinction between safe and unsafe water. Most ECDIS systems are designed for the safety contour to default to 30 metres.
