Ice Load Prediction Formulas for Icebreaking Cargo Vessels

Abstract

The ice load prediction for the icebreaking cargo vessels is discussed. Ice load includes the global ice loads and local ice pressures on the hull of the icebreaking vessels. The extreme ice loads are expected from large ice features and these loads are most likely to be concentrated at the bow area of a ship. The available ice load data from model tests and also from full-scale sea trials are collected and analyzed in the same format according to various ship-ice interaction processes. The ice load prediction formulas are compared with the measured data. Based on collected test data, semi-empirical ice load prediction formulas are recommended for large sized icebreaking cargo vessels.
