Ice tank simulation of icebreaking ships is clearly very dependent on the mechanical properties of the simulated ice. The conventional methods used to measure the mechanical properties of the simulated ice are time consuming and restricted to only one or two of the strength parameters. This report documents the ongoing development of a device, known as the Ice Strength Indexer, that measures the flexural, shear, and compressive strength of the ice continuously along the entire length of the ice tank. The report is divided into two sections. The first part discusses the development of the Indexer design, describes the ice model tests, and reviews the calibration of ice strength values. The second part presents a method for applying the output from the Indexer to correct the model resistance for variations in ice strength along the length of the tank.
