Marine Safety Circular 1503 Compliance Extension
The IMO subcommittee on Navigation, Communications and Search and Rescue (NCSR) has extended the deadline for Electronic Chart Display & Information Systems (ECDIS) software upgrades through August 31, 2017.
Software upgrades are defined by the International Hydrographic Organization (IHO). The IMO Guidelines on ECDIS Software Maintenance will be met by IHO-52 presentation library edition 4.0. A summary chart of the software changes and results for the mariner are available.
The decision to extend the deadline was based on the range of different makes and models of ECDIS. Various manufacturers will require different lead times to address the required upgrade. By September 1, 2017 software edition 4.0 should be installed on every bridge.
