RESEARCH ON PREVENTION OF SHIP ICING
Topside icing of ships may occur when sea spray or sea surface fog (arctic smoke) freezes on the ship's structure. Procedures of experimental laboratory and at-sea studies are described and diagramatically illustrated. Within the range of air temperatures down to -15 degrees and wind velocities up to 20 m/s, icing increases as the temperature falls and the wind rises; it may start at -2 degrees C, wind velocity 10 m/s. Anti-icing mats are effective for preventing icing and easing ice removal; rubber-coated canvas gives good anti-icing results; anti-icing paint requires further study. On fishing vessels, ice usually must be removed every 3-6 hours. Also suggested, without experimental testing, is the use of electrically heated radio aerials and radar antennae, and anti-icing greases for rotating parts of radars and other mechanically complicated structures.
