Abstract: Physical modelling is being used with increasing frequency to study the problem of ice-structure interactions. These studies comprise both basic research problems such as the determination of buckling or crushing loads for various structure geometries, as well as case studies of the ice loads on a particular design for an Arctic offshore structure. For both types of studies, there are specific requirements for the properties of the model ice and model structure, testing techniques and specifications for the ice tank where the model testing is performed. In this paper, the modelling laws which apply to physical modelling of the investigation of ice forces on structures are developed and used to define the properties of the ice and structure. The history, techniques and properties of model ice are reviewed. Some of the types of problems which can be reliably investigated using physical modelling techniques are briefly discussed and a summary is presented of some recent test results. Finally, some future developments and trends of physical modelling are explored.
