Abstract: A study has been performed to investigate the general level of agreement of predicting ice loads from various international experts. The format followed that of three previous studies of this type carried out in 1988,1994 and 1996. Four simple ice loading scenarios were developed and experts in ice mechanics were invited to predict the loads. Twenty-one Predictors took part in this study. The results show that there is a considerable improvement in agreement for loads generated by a level, first-year ice sheet on a vertical-sided structure. This improvement in agreement is attributed to new full-scale data which is publicly available. There is still a large range of predicted loads from first-year ridges (factor of five) and multi-year floes (factor of seven) interacting with a vertical-sided structure. There is a large range of disagreement (factor of over eleven) on predictions of level ice on a conicalshaped structure.
