Ask any ship manager about ECDIS and they will have a story or two to tell - and they won't all be good ones. ECDIS is a major advancement in the way we navigate our ships, but it's a complex subject and one that is frequently not sufficiently understood, leading to a host of problems from wasted money to grounded vessels.
This film is not just for the Officer of the Watch, but is equally applicable to their shore-based colleagues. As a 'Primer', it's aimed at officers and crew that are about to undergo training (generic or type-specific) or those whose job - onboard or ashore - doesn't justify the cost of a training course but who need a better understanding of the technology. As a 'Reminder', its intended for those that have already been trained and may have been working with ECDIS for some time, but not necessarily correctly. Or safely.
The subjects covered are:
The regulations: The mandatory carriage requirements for ECDIS (including SOLAS Chapter V and the Manila Amendments to the STCW code) and flag-state rules. The technology: What is ECDIS? Electronic charts: What is the critical difference between a Raster (RNC) and a Vector (ENC) chart? Why does it matter? What are the implications? What does RCDS mean? What sensor inputs are required? What happens if GPS is lost? Navigating with ECDIS: How does ECDIS affect the job of navigating your ship? The new procedures necessary for safe electronic navigation. Bridge Procedures for ECDIS: What to do when things go wrong, monitoring the accuracy of sensor input, the watch handover, software and system updates etc We discuss the importance of maintaining your situational awareness - continually confirming that "ECDIS is correct!" and the film stresses the crucial importance, using real world examples, of the potential danger to the OOW of blindly trusting ECDIS - "it's a computer, it must be right!"
