With the increase of vessels using ECDIS as primary and secondary navigational charts, several navigational incidents have been reported, where one of the contributory factors has been ECDIS-related. Overreliance on ECDIS 4. Safety depths appear in a bold font on the ECDIS screen. Remember -shallow contour should not overlap with the safety contour. The navigators must remember that the display of underwater obstructions or isolated danger symbols can change according to the settings of this safety contour which also marks the division between navigable (safe) and non navigable (unsafe) water.

It was produced in conjunction with the top 20 questions used for inspections designed by ECDIS Ltd. It exists only through AIS messages broadcast from another location. OCIMF has published guidance on how to improve policies and procedures concerning the safe use of Electronic Chart Display and Information Systems (ECDIS). ECDIS Safety settings and how to set ECDIS contour settings? ECDIS can be used as an Anti-Grounding Tool ; ECDIS can be used as a very effective Anti-Grounding tool when properly set up and used along with appropriate sensors. I2. A typical hazard that justifies an “isolated danger mark” atop of it, is a solitary rock. We had a vessel trialling Navmaster ECDIS with ENC and ARCS charts. We will now discuss the safety settings of ECDIS in more detail manner: There are four safety settings in ECDIS namely Safety Contour, Shallow Contour, Deep Contour and Safety depth.
