Abstract: The ice model basin is an essential part of the facilities for design of icebreaking vessels and Arctic offshore structures. One of the important issues while performing model tests in the ice model basin is to select a realistic model ice material which shows a correct similitude with natural sea ice. Usually in the refrigerated tank, model ice is grown from fresh water with appropriate chemical additives such as brine, urea or EG/AD/S. The first Korean ice model basin is now under construction at the Maritime Ocean Engineering Research Institute (MOERI) and is scheduled to open in 2009. This study focuses on reviewing material properties of model ice for possible use in the future MOERI ice model basin. The purpose is to correctly reproduce and to check the properties of model ice prior to the completion of MOERI ice model basin facilities. The elastic modulus and the flexural strength of EG/AD/S model ice originally developed by Timco (1986) were evaluated through a series of beam bending test. A cold room facility at the Korea Maritime University (KMU) was used for making model ice specimen. Since the cold room adopts a different freezing procedure in making model ice, the material properties of model ice grown and measured in a cold room slightly differ from published test results grown in the ice model basin. The reason for this difference is discussed in this study and future refinement techniques in making and testing of model ice specimen in a cold room are recommended.
