Introduction/Additional information: 

Introduction:

The ETA message shall be sent from vessel to shore (lock, open-able bridge or terminal) in order to inform that the vessel is heading towards the object and desires handling (locking, passing, berthing, transhipment, etc.) at the submitted date and time.

Additional Information / usage notes:

  • An acknowledgement by the RTA message (Inland ASM  FI 22) should be received within 15 minutes. Otherwise the ETA message should be repeated once. After additional 15 minutes the user shall be notified that no answer has been received.
  • A virtual MMSI number matching the country of the destination addressed by the ETA (see table  below) shall be used for each country, each national AIS network shall route messages addressed to other countries or different national AIS networks using this virtual MMSI number
  • In case no virtual MMSI number is available, the ETA message shall be sent to the closest AIS Base Station
  • UN country code, UN location code, Fairway section number, Object code and Fairway hectometre shall be derived from the ISRS code as part of the RIS Index published in the European Reference Data Management System (ERDMS).
  • The ETA shall always be transmitted in UTC but for input and display converted in local time of the destination.
  • The air draught shall be the minimum (e.g. with lowered wheelhouse / antenna mast) static air draught at speed = 0
