Abstract: The main objective of this paper is to estimate the total ice load due to sea spray icing on a vessel. Since published data sets on the distribution of the ice load over a ship were available only for medium-sized fishing vessels (MFVs) the ice accretion only on this type of vessel is considered. Based on the heat balance equation the formula of the local icing rate is derived and applied to find the formulas of the total ice growth rates on the ship's superstructure and bulwarks. Based on the Soviet data set on the distribution of the ice over an MFV, the ratios of the ice load on the ship's superstructure and bulwarks to the ice load on the entire MFV are determined and applied to calculate the total ice load on the entire MFV. The model is calibrated using published data sets. Simulations of icing are made for various air-sea and ship motion parameters. The results might be useful to calculate the ship's stability. For operational purposes the model might be run to calculate the actual and predict the icing rates and ice loads on an MFV.
