Since the North Standard launched ECDIS ETA, over 120 Members have adopted it, and crew have completed more than 7,000 anonymised assessments.

For many years, S-57 has been the standard data format used for the transfer of digital hydrographic data including Electronic Navigational Charts (ENCs).

Category Zone of Confidence (CATZOC) values are used to indicate the accuracy of data presented on charts to assist mariners with determining a safe Under Keel Clearance (UKC).

This blog explains exactly what CATZOC is and its importance in supporting safe navigation at sea.

When navigating with ECDIS, it’s important that mariners are confident in interpreting ENC symbology and how it relates to the area in which they’re operating. Below you can find information on how ENC symbols are displayed on ECDIS and useful resources to help you understand the symbols and abbreviations used in these charts.

The 9th session of the IMO’s Sub-committee on Navigation, Communications, Search and Rescue (NCSR 9) was
held from 21 to 30 June. Navigation and voyage planning requirements for fishing vessels, pleasure yachts and
small cargo ships operating in polar waters were finalized, as well as requirements to make inclinometers for the
measurement of heel angles compulsory for container ships and bulk carriers. The performance standards for
ECDIS were revised to accommodate the next generation of electronic navigational charts.

This AMSA bulletin focuses on navigation safety, in particular issues associated with the use of Electronic Chart Display and Information Systems (ECDIS).

Safety alert issued following a vessel grounding as a result of poor passage planning and sole reliance on the ECDIS.

The U.K. Marine Accident Investigation Branch (MAIB) and Danish Maritime Accident Investigation Board (DMAIB) published a study regarding the practical application and usability of ECDIS and future ECDIS design, training strategies, and the development of best practices.

The following data presents examples of vessels detained when serious deficiencies were pointed out during Port State Control (PSC) inspections carried out by the Australian Maritime Safety Authority (AMSA).
