Further to a note I sent to Roadkilt about a different MMSI number to mine for a ship namely Athens HIghway MMSI 370121000. His was 432930000. I googled both numbers and came up with same IMO number. Strange.
I ask Lloyds of London about this and they said the MMSI Roadkilt used was the correct number. This was because Athens Highway has changed flag from Panama to Japanese. This amendment will be in Lloyds register when they update their site. The call sign has also changed to 7JPL.
So apparently they say you should not identify a ship by the MMSI number as this changes frequently by Flag change and a ship should only be identified by the IMO number.
The first three number of an MMSI number identify the Flag. How you find that out I am not sure.
So do we still identify a ship by MMSi or IMO numbers that stay with the ship till it dies.
Smaller vessels are harder to find an IMO as we all know, and MMSI numbers are always readily available but can change.
Whats your choice.
I did mention to Mark Daniels a while ago that the IMO no. is the only constant for a ship, being allocated at build and staying with the ship throughout its life. It also has to be prominently displayed on the vessel.
Interesting post Graham, like Jack mentioned having your photo
knocked back because the MMSI number dont fit
