Title: imo number after 99 reached
Post by: Richard Paton on February 13, 2012, 06:46:35 pm
Hi all,

This may be a daft question but i was wondering what happens to the imo number sequence once they get to 99?  ???

Does it change to 00 or does it change to an 8 digit number as opposed to a 7 currently?

Cheers
Richard  :)

I guess when old ship get scrapped and delated from register, some new vessel can get that IMO number... so in this case it never reaches 00 :)

I think they'll move to eight digits. After all, the great thing in the IMO number is that it's unique. If they start recycling it, you get the same problems as when you're recycling phone numbers. Someone calls you in the middle of the night and tells you to stop seeing his daughter. Except that it's a bit different with ships.

Absolutely not!

As mentioned here on Shipspotting many times, IMO numbers are unique and never get re-used. As for what happens when 99 is reached, It is likely that IHS Fairplay have provision in place for such an event, but they're unlikely to make it public at this stage.

There is no shortage of numbers and, as Phil says, they will definitely not be recycled.

There are over 10,000 "9" numbers left
A large number of "8" numbers have not been issued yet (they are used for allocations for ships which are not newbuildings)
I suspect that there are a good number of never issued "5,6,7" numbers
I think that only a few "3" or "4" numbers have been utilised
As far as I know "1" numbers are at present mainly used for yachts; also some of these and some "2" numbers have been used for small vessels outside the IMO system and only appear if that vessel subsequently applies for an IMO number (eg http://www.shipspotting.com/gallery/photo_search.php?imo=2838358)
Some "invisible numbers" have been used for database purposes as temporary internal IDs
And of course, though there may be technical reasons not to use them, no "0"(zero) numbers have been used, that's another 99,999 more.
