In this study, the design parameters of the world's ice-transiting vessels, currently in service or under construction, were collected and a database of principal particulars for each ship was established. To understand the recent design trend, ice-transiting vessels were categorized into 4 groups: conventional icebreakers, icebreaking tug/supply/research vessels, icebreaking passenger/car ferry and ice-strengthened cargo vessels. The changes in the principal particulars for each group were reviewed and summarized. It was found that the most significant change in the design of ice-transiting vessels was the increment of large commercial cargo vessels. It is believed that the recent hike in oil prices and the booming Russian economy have resulted in the need for year-round operations with bigger ships in the Baltic Sea and in the Sea of Okhotsk as well as along the Northern Sea Route in the Russian Arctic Sea.
