Ice is a very particular material that does not obey Amonton’s law of friction. Research on frictional phenomena between sea ice and ice-class vessels or platforms in arctic regions is still in its early stage, even though ships and platforms are greatly influenced and moved by the friction force of sea ice. In this paper, various friction tests were carried out, using freshwater ices and model ices in the Korea Research Institute of Ships and Ocean Engineering (KRISO) ice tank, to find the fundamental friction characteristics of ice and to estimate accurate ice friction force between ship and sea ice. As a result, we not only evaluated a painting method by using matting powders for ice-breaking ship models, but also found that the friction with an ice depends on the fundamental roughness and the supplemental roughness of material by measuring the roughness parameters of the plates. This study is intended to contribute to the understanding of the friction characteristics with ice.
