Abstract

Recent exploration of natural resources and their transportation in the arctic or sub-arctic regions and the increase of traffic through the Northern Sea Route (NSR) have stimulated new structural concepts and ship designs. To evaluate the design and performance of these structures and ships, model tests in an ice tank are the preferred evaluation tool. The Maritime Ocean Engineering Research Institute (MOERI) is building the first ice tank in Korea to meet the increasing research and development challenges and opportunities arisen from the recent demands. A study to review the state-of-the-art modeling techniques and methodologies used in existing refrigerated model basins, including model ice production and ice modeling techniques, is being conducted to assist their adaptation to the new tank. This paper reviews and summarizes the ice modeling techniques used in different ice modeling facilities worldwide. The physical and mechanical properties of different types of model ice and their scalability are critically assessed. Comparisons of mechanical properties from sea ice and model ice are presented and discussed.
