Reduction of Corrosion in Ships' Cargo Tanks by Dehumidification Available to Purchase

It is generally accepted that the oil cargoes most commonly carried by bulk oil vessels are not in themselves corrosive to iron and steel, although some of their constituents when mixed with water may cause trouble. But water is the culprit; and sea water in particular. The electrochemical theory of corrosion which was originally put forward in 1903 is now so generally accepted that there is no need to go into any detail about it in this paper. It should, however, be mentioned, as, unless we fully understand the mechanics of corrosion, we cannot successfully combat it.
