This information paper provides guidance to enhance policies and procedures regarding the safe use of Electronic Chart Display and Information Systems (ECDIS). With more vessels using Electronic Navigational Charts (ENCs) for primary or secondary navigation, there have been several significant navigational incidents over the last decade where one of the contributing factors has been ECDIS-related. Recommendations on Usage of ECDIS and Preventing Incidents takes into account ECDIS-related navigational incident findings and safety-related observations from OCIMF’s Ship Inspection Report Programme (SIRE). To provide practical support and guidance, the information paper draws upon this analysis to provide recommendations for improving ECDIS-related practices and preventing ECDIS-related navigational incidents. This information paper is aimed at ship owners, operators, Masters, Navigating Officers and bridge team members including pilots as well as ECDIS system manufacturers. Key chapters in the information paper cover ECDIS carriage requirements, ECDIS training and familiarisation, passage planning and alarm management.
