METHODS FOR THE ALLEVIATION OF SHIP ICING

Tests were made, both in an icing wind tunnel and at an outdoor test site, of various proposals for the alleviation of the problem caused by the freezing of sea spray on the superstructures of ships. Of the devices evaluated, a pneumatic de-icing technique proved the most effective under all conditions for the de-icing both of masts and of flat surfaces such as bridge fronts. Next in effectiveness was the use of ethylene glycol as a freezing point depressant to reduce the strength and adhesion of the ice. Several passive methods were tried, but none was very effective, with the exception of a plastic foam with an outer layer of neoprene rubber. (Author)
