IMO Numbers, what are they?
« on: Feb 03, 2012, 08:33 AM »
I am reading William Mayes excellent cruise-ship book (Volume 3) and he now has a IMO number for each ship. What are these? I am guessing every ship is allocated an IMO number to identify her.
Could someone give me some info about these numbers. Who gives them out and why.
Did QE2 have such a number, if so, what is it.
In advance, many thanks to whoever gives me information.

As well as their call sign, every ship has an IMO number

Queen-Elizabeth2 - IMO 6725418

And here it is being put to good use!!  ;)

Before the IMO came into existence - all ships had an 'Official number'


'the International Maritime Organization – is the United Nations specialized agency with responsibility for the safety and security of shipping and the prevention of marine pollution by ships.'

Many thanks for this, Twynkle. Another fact for me to digest, does every ship have a number that remains constant, no matter how many name changes. This could be useful to track older cruise ships which become floating casinos and are dropped from books like Berlitz Cruise Guide. And would QE2 retain her number even if she becomes a hotel?

Every powered ship over 100 gt has an IMO number. This hull number never changes, despite changes in ownership. Just been looking through my photo database but can not locate the folder with the numbers I have recorded for the ships I have sailed on. They are welded into the ships steel structure at various locations below deck (ie, on bulkheads, machinery spaces), prominent positions on deck, etc. Plenty of info on Google.

Many thanks, Skilly, for information. I asked because I have been trying to trace several older ships built in the 1980s and 1990s and if, as you say, the IMO number is 'engraved' into the ship's structure, it becomes an excellent way to trace a ship's history. For instance I have been trying to trace the 16 ships of Renaissance Cruises ( the Little Rrrrs and the Big Rrrs as I call them) which had the most unimaginative names for cruise ships I have ever come across. Also the Lady Sarah and Lady Diana. Mayes' excellent books have them all.

If you are happy to trust Wikipedia, and I cannot spot any errors on the 30000 grt ships, although on the smaller vessels I am aware that Renaissance II has changed hands after its life of Easy Cruise One, as has Renaissance VI since its days as the Hebridean Spirit, the otherwise full listing of Renaissance ships is to be found:

It would appear that Lady Sarah and Lady Diana have become Megastar Taurus and Megastar Aries repectively under the Star Cruises/Genting banner but Ais is only showing current voyage information for one vessel:

http://www.marinetraffic.com/ais/shipdetails.aspx?mmsi=353913000

Perhaps her sister is under overhaul.

Dear Tyne Turbine. Many thanks for your answer and sites. I see from Marine Traffic that Megastar Aries (formerly Lady Sarah) also has an MMSI number. What are there? (I think I might stay with IMO for the moment, but I will go to the Marinetraffic site and see what other info I can find) For fans of the Royal Viking ships, the R.V. Sea, now named Albatros, was in port today (Auckland) so I went today to see her. She's another of my old favourites that i'm glad to see are active still.
And could 26/10/1991 by Lady Sarah's launch date?
Many thanks for all your help, everyone. My lists of cruise ships expands onwards.

Hi for those that don't know he MMSI is in effect the ships phone number when calling on a modern DSC (digital selective calling) VHF radio.

Previously you would call a ship on open channel 16 and when you had raised her go to a working channel. Now you are expected to know her MMSI number and call her directly. The MMSI can be obtained from info on AIS. However if you are a small vessel without AIS it is down to luck in hoping they are still monitoring channel 16. AIS receivers are for this reason now becoming very popular on small private vessels.

Hope this helps.

Pleasure if I can be of help Mauretania 1907, what else can I say to someone who bears the name of one of the Tynes most significant products.

I hope the passengers on the Albatros are enjoying the voyage as much as I enjoyed her sister the Boudicca last month.

You may be interested in this poor image of the Royal Viking Sea on one of her first voyages at North Shields on the River Tyne when she was filling in during the refit period of the regular ferry Leda on the overnight service to Bergen:

Dear Tyne Turbine - and other helpful people. I am trying to trace the history of a ship known as Sally Albatross - this is a ship which died and was reborn so to speak. Originally built as VIKING SAGA in 1980, she became the SALLY ALBATROSS in 1986.
On Jan 9, 1990 a fire broke out during the annual overhaul and the ship became a CTL. Her remains were towed away, the superstructure was chopped off and the hull and engines used for the(re) building. She was launched July 25, 1991 as Sally Albatros but in March 1994, she ran aground while approaching Helsinki. 2000, she became Superstar Taurus, in 2002, she was Silja Opera, in 2006, she was Opera and in 2007, she was Cristal for louis Cruise Lines. She is not listed in imonumber.com, has she finally met her doom?
My question? her IMO number is now 7827213 but was that her original number? I ask this since she was 'reincarnated' after the fire.
Also, another question, please bear with me. How to find IMO numbers for those ships recently scrapped, eg Ausonia/Ivory?
Thank you all for your patience and help, it is truely appreciated.

O Twynkle, what have you done to me. This site is awesome, does it cost anything to join. Mauretania has curled up in delight, chasing IMO numbers. AND Ellen has found the various incarnations of Sally Albatross all have the same number, so she is essentially the same ship, altho if you look at her, you'd think there were two ships. AND what is more, I've found IMO nos for some 1970's ships - even Kludas in his excellent Passenger Ships of the World series did not include them, mind you, the older ships had a registration number instead. I will return later, there is a radio program I want to hear.  Many, many thanks, Ellen. ;D

 ;D More to my insane search for ship facts. I started to compile a list of cruise ships built from 1950 onwards, it grows and grows. I limited the list from GRT 1,000 and up, else I would have lots of little ships crawling out of every backwater on Earth. I've found some fascinating stories, for instance that of Sally Albatross, which survived a fire and grounding and was still going as Louis Lines Cristal at least until end of 2009 (but I think SOLAS has finally finished her off) I found a couple of ships whose stories just about could make me cry. Check out Regent Sky, ex Stena Baltica for the saddest cruise ship story, although Cunard Ambassador runs it a good second. Balconies for sheep, anyone? :-\ Many thanks for help it is gratefully received. Ellen.

Trying to not go more off topic, SS Rotterdam still appears to have hers as well: IMO 5301019

Reading parts of the above article it makes sense they all still appear to have their IMO numbers.

Is there any place, ore some sort of registry of IMO numbers (not Marine Traffic, but the actual governing body) online? In the case of the ss Rotterdam my guess is that the number is still assigned to the ship, but it is inactive, since she is a building, not a ship. I would want to take here out to see, most of not all WTD's are wide open and can not be closed and without some serious work.

There is this?

https://gisis.imo.org/Public/Default.aspx


Thank you Peter, I have just looked up the ss Rotterdam, and she is registered as a Accommodation Vessel/Stationary, this confuses me, since she is also register as a building, if I have some spare time I will try to see if I can go to Rotterdam City Hall or Archive to see what she actually is. If she is technical a vessel, there would be rules that need to be applied I would presume, although it might be different is she is a Stationary vessel. The company to which the ship is registered has 0 ships listed, so a Stationary vessel might be an inactive status.


Queen Mary has the same status, fun fact: between 1940 and 1947 she was a troopship instead of General Cargo/Passenger Vessel. Makes me wonder when she became a troopship if here actual registry was changed, or somebody just filled that in when they entered it original.


QE2 is a differente story, she is still registered as a Passenger/Cruise vessel, with the flag of Vanuatu, registered to a company called 'QE2 Shipping LLC', which has also 0 vessels under ownership.


Did a little bit more searching, and according to them Queen Mary 2 and QV is registered to Carnival PLC in Southampton, whilst QE is registered to Cunard Line LTD.

Could just be a error in entering, altrough it seems to be the official website for IMO.


Cunard Line LTD is a Bermuda registered company, but it's company address in in Southampton, has one ship as owner (QE), and 3 as operator.

From the Wikipedia article (I linked in a previous post) the IMO number stays with the hull for its lifetime apparently - so SS Rotterdam would have hers for example.

There is a lot of knowledge to be gained by reading the earlier postings on this thread.

For instance :
As well as their call sign, every ship has an IMO number

Queen-Elizabeth2 - IMO 6725418
http://www.vesseltracker.com/en/Ships/Queen-Elizabeth-2-6725418.html

As confirmed in a much later posting :

That's pleasantly surprising  :) . QE2 appears to still have hers: IMO 6725418

Also some valuable general information :

Every powered ship over 100 gt has an IMO number. This hull number never changes, despite changes in ownership. Just been looking through my photo database but can not locate the folder with the numbers I have recorded for the ships I have sailed on. They are welded into the ships steel structure at various locations below deck (ie, on bulkheads, machinery spaces), prominent positions on deck, etc. Plenty of info on Google.

And the all important link to much more :

'the International Maritime Organization – is the United Nations specialized agency with responsibility for the safety and security of shipping and the prevention of marine pollution by ships.'

http://www.imo.org/Pages/home.aspx

Paraphrasing Skilly then, the IMO number is the equivalent of the chassis number of a car; it never changes, even though the registration (or in the case of a ship the call sign) may change.
