External ice reinforcements for ships in operation

[摘要] The subject of the proposed article is the external ice reinforcements of the ship hull. Ice reinforcements for the Russian commercial fleet are an urgent topic, but the traditional measures of such matter (replacement of the shell plating, installation of an intermediate frame) are expensive and require a large amount of preparatory work. External reinforcement are an alternative, which is much cheaper than their installation. As a rule, it is performed in the form of a rolling profile of various shapes (most often a semicircle) welded to the outer skin. In addition to the lower cost, they have a number of other advantages.
