Facts about Electronic Navigation Charts and carriage requirements - free publication available!

We would like to draw your attention to a publication which has been produced by the two regional Electronic Navigation Chart (ENC) Centres, Primar Stavanger and IC-ENC. This publication is a revised version of the first edition produced in 2004. It incorporates information provided by IMO Member States in response to IMO Circular Letter 2666 with regard to acceptance of Electronic Chart Display and Information Systems (ECDIS) to meet carriage requirements.


Although ECDIS carriage requirements are currently under review by the IMO, and in particular by the Navigational Sub-committee, which met this week, this publication gives the current requirements. The latest news from the Navigation Sub-committee meeting, including any future carriage requirements, will be reported in a future Weekly NEWS.
