The Singapore Electronic Navigational Chart (ENC) covers Singapore Port Waters and their approaches.

The electronic navigational chart (ENC) is a digital chart product intended to be used in conjunction with Electronic Chart Display and Information Systems (ECDIS).

The Electronic Navigational Chart (ENC)

The electronic navigational chart (ENC) contains information on features useful for navigation such as bathymetry (water depths), coastlines, obstructions, beacons etc. and complements traditional paper charts. Fully compliant with the chart standards and specifications set by the International Hydrographic Organization (IHO),in particular S57 Edition 3.1, the ENC contains supplementary nautical information useful for safe navigation above and beyond what is shown on traditional paper charts.

The latest edition of the Singapore ENC is Release 2012.1, covering Singapore Port Waters and their approaches.

The Electronic Chart Display and Information System (ECDIS)

The Electronic Chart Display and Information System (ECDIS) is the navigation information system which is considered the legal equivalent of the nautical chart, displaying selected information from an ENC.  It is integrated with data from positional and, optionally, other sensors.Both the ECDIS software and hardware comply with the ECDIS performance standards set by the International Maritime Organization (IMO).

The Maritime and Port Authority of Singapore (MPA) has invested in additional supporting infrastructure such as the Differential Global Positioning System (DGPS) broadcast service, which can be used with ECDIS to improve positioning accuracy and navigational safety.

A powerful navigational tool, the ECDIS when interfaced with navigational sensors such as DGPS is able to provide:

  • Real-time positioning: The system is able to track the actual position of the vessel and display it in real-time.
  • 24-hour, all-weather: It is able to operate in all weather conditions, both day and night, thus enhancing navigational accuracy critical in confined waters.
  • Anti-grounding and anti-collision warnings: The ECDIS can provide anti-collision and anti-grounding warnings, when interfaced respectively with an Automatic Radar Plotting Aid (ARPA) and an echo sounder.
  • Easier navigation: The ECDIS has the capacity to carry out course planning, route monitoring, waypoint checking and estimated time of arrival (ETA) calculation.


The Singapore ENC when used with the ECDIS further enhances safe navigation within Singapore waters and its approaches. As the system is a pproved by the IMO as a paper chart equivalent, vessels equipped with it need not carry paper charts as is normally required under the Safety of Life at Sea (SOLAS) Convention.


The Singapore ENC consists of 13 harbour category cells covering Singapore waters and its approaches:
