Ship Identification Number [edit]

The ship number consists of the three letters "IMO" followed by a

unique seven-digit number assigned to sea-going merchant ships

under the International Convention for the Safety of Life at Sea

(SOLAS).[1]

History [edit]

In 1987 the IMO adopted Resolution A.600(15), "aimed at enhancing

maritime safety, and pollution prevention and to facilitate the

prevention of maritime fraud" by assigning to each ship a

permanent identification number which would continue despite any

subsequent change in the vessel's name, ownership or flag. When

made mandatory, through SOLAS regulation XI/3 adopted in 1994

and which came into force on 1 January 1996, it was applied to

cargo vessels that are at least 300 gross tons (gt) and passenger

vessels of at least 100 gt.[1] In the SOLAS Convention "cargo ships"

means "ships which are not passenger ships".[2] The IMO scheme

does not however apply to:

Vessels solely engaged in fishing

Ships without mechanical means of propulsion

Pleasure yachts

Ships engaged on special service (e.g. lightships, SAR vessels)

Hopper barges

Hydrofoils, air cushion vehicles

Floating docks and structures classified in a similar manner Ships of war and troopships

Wooden ships[1]

"IMO 9319466" on the helideck ofM/S Finmaid

In December 2002, the Diplomatic Conference on Maritime Security

adopted a number of measures aimed at enhancing security of shipsand port facilities. This included a modification to SOLAS Regulation

XI-1/3 to require ships' identification numbers to be permanently

marked in a visible place either on the ship's hull or superstructure

as well as internally and on the ship's certificates. Passenger ships

should also carry the marking on a horizontal surface visible from

the air.[1]

Assignment and Structure [edit]

When introduced, the IMO adopted the existing unique ship

numbers applied to ships listed by Lloyd's Register since 1963.[3][4]

IMO ship identification numbers are assigned by IHSFairplay

(previously Lloyd's Register-Fairplay)[1]

For new vessels the IMO number is assigned to a hull during

construction, generally upon keel laying. Many vessels which fall

outside the mandatory requirements of SOLAS have numbers

allocated by Lloyd's Register or IHS Fairplay in the same numerical

series, including fishing vessels[5] and commercial yachts.[6]

The IMO ship identification number is made of the three letters

"IMO" followed by the seven-digit number. This consists of a six-digit

sequential unique number followed by a check digit. The integrity of

an IMO number can be verified using its check digit. This is done by

multiplying each of the first six digits by a factors 7 to 2

corresponding to their position from left to right, and adding those

products together. The rightmost digit of this sum is the check digit.

For example, for IMO 7654329: 77 + 66 + 55 + 44 + 33 +22 = 139.[7][8]

Company and Registered Owner

Identification Number [edit]

In May 2005, IMO adopted a new SOLAS regulation XI-1/3-1 on the

mandatory company and registered owner identification number

scheme, with entry into force on 1 January 2009.[9]

The Regulation provides that every ship owing and management

company shall have a unique identification number and other

amendments require these numbers to be added to the relevant

certificates and documents in the International Safety Management

Code (ISM) and the International Ship and Port Facility Security Code(ISPS).[1] Like the IMO ship number, the company identification

number is a seven-digit number with the prefix IMO. For example,

for the shipAtlantic Star, IMO 5304986 refers to the ship manager

Pullmantur Cruises Ship Management Ltd and IMO 5364264 to her

registered owner, Pullmantur Cruises Empress Ltd.[10]
