A special classification that, on request of the owner, may be assigned by the classification society to indicate that the ship is suitably constructed, powered and otherwise equipped for navigation in ice of a specified age and thickness. The leading classification societies publish a range of ice classes that are equivalent to the Finnish-Swedish Ice Class Designations. Lloyd’s Register ice classes, for example, include 1 AS, 1A, 1B and 1C, while Bureau Veritas ice classes are IA SUPER, IA, IB and IC.
