ECDIS Module 9 – Safety Features



Understand how ECDIS really protects your ship

This module focuses on the core safety functions of ECDIS, the tools that actively prevent groundings, route errors, and unsafe navigation decisions when correctly set and understood.

You will learn how to properly use and interpret:

• Safety Depth & Safety Contour
• Look-Ahead Sector and alarms
• Route checking vs ENC dangers
• Alerts hierarchy (caution, warning, alarm)
• User-defined danger lines and anchor watch

This is not theory-only content.

The module is designed for officers of the watch, cadets, and junior officers who want to understand why accidents still happen even with ECDIS on.

✔ Practical

✔ Operational mindset

✔ Focused on real bridge scenarios

✔ Ideal for watchkeeping improvement and interviews

If you use ECDIS every day, this module helps you use it correctly, consciously, and safely.
