ESTIMATING THE EXTENT OF THE SPRAYING ZONE ON A SEA-GOING SHIP

Small and medium-sized fishing vessels and small cargo ships are most likely to experience icing, owing to their size. A ship capsizes when the ice load reduces stability by raising the center of gravity and lowering the metacentric height. Ice on elevated objects reduces ship stability more than an equivalent amount on the ship deck. A review of Soviet publications on ship icing disclosed a unique field data set covering several cases of ship icing, documenting air-sea and ship motion parameters and measured heights of ice accretion on the ship foremast. This enabled a determination of the relationship between the maximum extent of spray in the vertical direction and the air-sea and ship motion parameters. The purpose of this article is to introduce the methods used to make this determination and to test the performance of the improved ship spraying model in which the new relationship has been applied.
