ECDIS Safety Settings and UKC Management

Издание на английском языке
This publication aims to enhance understanding of the principal Electronic Chart Display and Information Systems (ECDIS) safety settings and provides guidance to support their correct application by the ECDIS operator. It explains underkeel clearance (UKC) and how this should be calculated and managed by the ECDIS operator.
The information provided is not a substitute for correct adherence to company safety management system (SMS) requirements or the manufacturer's own operational manuals. It should be used in conjunction with recognised type-approved training and onboard best practices.
ECDIS safety settings must be configured correctly to ensure sufficient UKC, accurate interpretation of electronic navigational charts (ENCs) and proper identification of charted objects as navigational dangers or hazards. Incorrect set-up of ECDIS safety settings has led to numerous shipping incidents over the years.
