Abstract: One of the most challenging problems in the design of ice-resistant platforms is to predict ice loads on the subject structure. Ice basin model tests can offer a helpful tool to achieve this. There are some difficulties in performing the tests themselves. Among those is the problem of modelling the ice to obtain the required mechanical properties. This paper discusses a method for predicting ice loads on iceresistant offshore platforms. The method is based on making model tests under simulated ice conditions and generating a multi-factor regression model to describe dynamic characteristics of the interaction process with the help of model test data obtained under actual mechanical properties of the ice. This regression model enables to determine dynamic parameters of the structure for arbitrary (within a certain range of values) mechanical properties of the ice and velocities of interaction with ice features. The paper shows several already validated regression models for ice loads on sloping structures and assesses their accuracy.
