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.
