Division 3.3 In the case a Flag State has the technical capability to send all above messages and contents in the so-called NAF-format on behalf of its operating vessels, that Flag State may — after bilateral agreement between the Flag State and the Commission — transmit this information via a secured transmission protocol to the Commission of the European Communities in Brussels. In that case, some extra information will be added — as a kind of envelope — to the transmission (after the AD information)
United Kingdom
| FR | m | (from; party alfa ISO-3 country code) |
| RN | m | (serial number of the record for the relevant year) |
| RD | m | (date of transmission in yyyymmdd format) |
| RT | m | (time of transmission in hhmm format) |
Example (with data of above)
//SR//AD/XEU//FR/NOR//RN/5//RD/20051004//RT/1320//SQ/1//TM/COE//RC/IRCS//TN/1//NA/VESSEL NAME EXAMPLE//IR/NOR//XR/PO 12345//LT/+65.321//LG/-21.123//RA/04A.//OB/COD 100 HAD 300//DA/20051004//TI/1315//MA/CAPTAIN NAME EXAMPLE//ER//
The Flag State will receive a ‘return message’ specifying:
| SR | m | (= start of record) |
| AD | m | (ISO-3 country code of Flag State) |
| FR | m | XEU (= to Commission of the European Communities) |
| RN | m | (serial number of message in current year for which a ‘return message’ is sent) |
| TM | m | RET (= ‘return’) |
| SQ | m | (serial number of original message for that vessel in current year) |
| RC | m | (international radio call sign mentioned in original message) |
| RS | m | (return status — ACK or NAK) |
| RE | m | (return error number) |
| DA | m | (date of transmission in yyyymmdd format) |
| TI | m | (time of transmission in hhmm format) |
| ER | m | (= end of record) |
