The exported file contains complete information about the required ENCs and can be used for coordination with shore-based hydrographic offices during voyage preparation.

ENC statuses

Important

Before starting the voyage, be sure to check the currency of all ENCs for the entire voyage period. Outdated charts may contain outdated navigational information and pose a safety threat.

Possible ENC statuses:

  • Current — the chart contains all necessary updates for the voyage period

  • Update required — the chart needs to be updated before the start of the voyage

  • License expiring — the license expires during the voyage period

  • Missing — the chart is not installed in the system

ENC edition types

Official ENCs:

  • Published by national hydrographic offices

  • Comply with IHO S-57 standards

  • Are an adequate replacement for official paper nautical charts

  • Updated regularly

Unofficial ENCs:

  • Published by commercial cartographic companies

  • May contain additional information

  • Do not have official status

  • May be used as a supplement to official charts, for areas without official coverage

Note

For areas with incomplete official ENC coverage, the use of unofficial charts as backup cartographic support is permitted.

Route coverage check

When analyzing the ENC list, pay attention to:

  1. Coverage continuity:

    • The entire route must be covered by ENC cells

    • Gaps in chart coverage are unacceptable

  2. Chart scales:

    • Availability of cells at the required scales for all sections

    • Large-scale charts for port approaches and narrow channels

  3. Currency:

    • All ENC cells must be current

    • License validity must not expire during the voyage period

Warning

Navigating in areas without chart coverage or with outdated charts poses a serious threat to navigational safety and may be a precursor to a navigational incident.

Integration with voyage planning

The ENC by route report is used for:

  • Quick verification of the ship’s ENC collection by Port State Control

  • Route adjustment in case of insufficient chart coverage

  • Planning chart requests to shore-based hydrographic offices

  • Assessing vessel readiness for the voyage

  • Documenting the ENC collection status for port authorities
