I am sure this must have been asked before, but is there a NUMERICAL list of IMO numbers?
I have a photo where the name of the vessel is obscured as are the last 3 digits of the IMO number.
It would be so much easier to plough through a few hundred numbers than thousands.
Any ideas?
It's fairly simple to build your own list using a spreadsheet. The first six digits rise sequentially, while the seventh is a check digit derived from the previous six numbers.
So if you start at, say, 960000, the next one will be 960001 and so on.
The check digit would be calculated with the 1st number multiplied by 7, the 2nd by 6, the 3rd by 5 and so on. All the answers are added up and the last digit from the answer is the check digit.
Using that calculation we can determine that 960000 has a check digit of 9, which is assigned to a Vietnamese cargo ship THAI BINH 35.
960001 has a check digit of 1 which is assigned to another Vietnamese general cargo ship, ROYAL 16 (which IHS bizarrely call a bulk carrier!)
If you don't want to go to all the fuss of calculating the check digit, you can just type in the first few numbers to the search facility on Marine Traffic and a list will pop up.
Hope this helps,
Steve
