dc.description.abstract To correctly estimate ice load and ice resistance on ship's hull, it is essential to understand the material properties of sea ice during ice field trials and to perform the proper experimental procedure by gathering ice strength data. The first Korean-made icebreaking research vessel ARAON had her second sea ice trial in the Arctic Ocean during July and August, a summer season of 2010. This study describes test procedures to obtain proper sea ice strength data which provides the basic information to ship's performance in ice-covered sea and to estimate the correct ice load and ice resistance on the IBRV ARAON. The data gathered from three sea ice field trials during the Arctic voyage of the ARAON includes ice temperature, ice salinity, ice density, ice compressive strength, ice flexural strength and failure strain of sea ice through the sea ice thickness. This study analyses the gathered sea ice data in comparison with data from the first voyage of the ARAON during her Antarctic Sea ice trial in January, 2010, sea ice field tests in Svalbard in April, 2010 and another Arctic sea ice trial in August, 2011. -
