Applicability: All builders, owners and operators

The IMO has consolidated previously issued guidance relating to Electronic Chart Display and Information Systems (ECDIS) into one guidance document, published as Circular MSC.1/Circ.1503. This Circular gives advice on:

  • SOLAS chart carriage requirements
  • ECDIS software maintenance
  • operating anomalies identified within ECDIS
  • differences between raster chart display system (RCDS) mode and ECDIS mode
  • ECDIS training
  • transitioning from paper charts to ECDIS navigation
  • guidance on training and assessment in the operational use of ECDIS simulators.

It also includes a list of ECDIS apparent operating and display anomalies, and references to IMO performance standards for ECDIS and other circulars related to ECDIS.

Ship operators, masters and deck officers on ECDIS-fitted ships are encouraged to use this guidance to improve their understanding and facilitate safe and effective use of ECDIS.
