Singapore Electronic Navigational Chart
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 System (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 covers Singapore Port Waters and their approaches.
The Electronic Chart Display and Information System (ECDIS)
The Electronic Chart Display and Information System (ECDIS) is a 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 approved by 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 16 harbour category cells covering Singapore waters and its approaches:
|SG5C4030||West Jurong Anchorages and Temasek Fairway|
|SG5C4031||Western Approaches to Jurong Island|
|SG5C4033||Tuas Bay, West Jurong Channel and Pesek Basin|
|SG5C4034||East Jurong Channel, Pasir Panjang Terminal and West Keppel Fairway|
|SG5C4035||Western Anchorages, Jong Fairway and Cruise Bay|
|SG5C4036||Raffles Lighthouse to The Sisters|
|SG5C4037||Keppel Harbour, Tanjong Pagar Terminal and Approaches|
|SG5C4038||Johor Strait – Western Part|
|SG5C4039||Western Approaches to Main Strait|
|SG5C4041||Pulau Sebarok to Changi|
|SG5C4043||Kuala Johor and Sungai Johor|
|SG5C4044||Johor Strait – Eastern Part|
|SG54044B||Pelabuhan Johor (Johor Port)|
How to access or purchase
To access, view and navigate with the Singapore ENC, it must be used in conjunction with a type-approved ECDIS, which is available from authorised commercial vendors.
Alternatively, to view the Singapore ENC, you may download a copy of the free data viewer from SevenCs called SeeMyDEnc.
Registered Singapore ENC users can obtain monthly incremental updates from their Singapore ENC distributor.

Q1: What is the Singapore ENC?
A1: The Singapore Electronic Navigational Chart (ENC) is a digital database containing hydrographic chart information covering Singapore waters and its approaches. It is necessary for safe navigation and supplements data that is in paper charts. Produced and quality assured by the Hydrographic Department of the Maritime and Port Authority of Singapore (MPA), the Singapore ENC complies with the International Hydrographic Organization (IHO) S57 Edition 3.1 specifications.
Q2: What is the purpose of the Singapore ENC?
A2: The Singapore ENC was developed to supplement the traditional paper format. In 1994, the Hydrographic Department of the Maritime and Port Authority of Singapore (MPA) embarked on a project to produce the ENC. The first official Singapore ENC was released for commercial use in 17 March 1998.
Malacca and Singapore Straits Electronic Navigational Chart
The Malacca and Singapore Straits Electronic Navigational Chart (MSS-ENC) covers from One Fathom Bank in the Malacca Strait to Eastern Bank in the South China Sea.
The MSS-ENC is an official ENC, meeting the International Hydrographic Organization specifications and standards. Used together with ECDIS, it enhances safe navigation and meets Safety of Life at Sea (SOLAS) Convention chart carriage requirements.
The Latest 5th Edition of the MSS-ENC includes updated information from the recent joint hydrographic survey of areas critical to navigation in the Straits. The MSS ENC now includes additional information in the form of one-metre contour depth intervals in under keel clearance-critical areas which would enable more accurate determination of under-keel clearance and enhanced navigational safety and efficiency for vessels transiting the Straits.
One Fathom Bank to TanjungTuan
Raleigh Shoal to Fair Channel
IyuKechil to Eastern Bank
IyuKechil to Raffles Lighthouse
Buffalo Rock to Johor Shoal
Nongsa to Eastern Bank
