accordance with IMO ECDIS Performance Standards and IHO S52 Ed 6.1.1. However, this is also still the same thing or close in the new S-101 draft standard where, it is defined that isolated dangers of depth equal to or less than the own-ship safety contour must always be displayed in ‘safe waters’ (waters deeper than the safety contour).

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. The Safety Contour is one of the most critical safety alarms used in ECDIS. 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. 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.

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.

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; Author recommends that the safety contour value should be used for the safety depth on ECDIS with such feature.Where the manufacturer provides for separate controls for safety depth and safety contour, the user can substantially increase their situational awareness by choosing, for example, values as indicated in the Figure Unlike paper charts where source data diagrams are mostly provided, ENCs (Electronic Navigation Charts) do not provide this information.

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.
