Extended ship static and voyage-related data

Details:

Parameter No. of bits Description
Message ID 6 Identifier for Message 8; always 8.
Repeat Indicator 2 Used by the repeater to indicate how many times a message has been repeated. 0 – 3 0 = default 3 = do not repeat anymore
Source ID 30 MMSI number of source station.
Spare 2 Not used. Set to zero.
IAI 16 DAC = 001; FI = 24 (See ITU-R M.1371-3, Annex 5, § 2.1)
Message Linkage ID 10 A source specific running number, unique across all binary messages equipped with Message Linkage ID. Used to link additional information to the message by a Text Description message. The Message Linkage ID and the first six digits of the source MMSI uniquely identify the sent message.

0 = not available = default
Air Draught 13 Air Draught is the vertical distance from the ship’s waterline to the highest point on the ship (e.g., top of ship’s mast), in 0.1 metre steps. Air Draught = total vessel height (e.g., from bottom of keel to top of ship’s mast) minus the maximum static loaded draught.

Ice class 4 Ice Classes as defined by:
IACS = International Association of Classification Societies PC = Polar Class. For further details, see IACS Req. 2007 Requirements concerning POLAR CLASS and MSC/Circ.1056 and MEPC/Circ.399 on Guidelines for ships operating in Arctic ice-covered waters.FSICR = Finnish-Swedish Ice Class Rules. For further details, see Finnish Maritime Administration’s Bulletin No.10/10.12.2008 Ice class regulations 2008 (Finnish-Swedish ice class rules). Note: Authorized classification society equivalents for the Finnish-Swedish Ice Class Rules should also be recognized, as issued in the Finnish Maritime Administration’s Bulletin No.4/2.4.2007 (as amended). Both bulletins can be found at www.fma.fi(link is external).

RS = Russian Maritime Register of Shipping. For further details see Rules for the classification and construction of seagoing ships, Edition 2008.
