The International Ice Patrol (IIP) was established after the Titanic collided with an iceberg off the eastern coast of Canada in 1912 and sank, killing more than 1,500 people. Recently, the IIP has analyzed satellite images and provided safe operation information to vessels by tracking the occurrence and movement of icebergs. A large number of recent arctic studies mainly deal with sea ice formed by freezing seawater related to sea routes and resource development. The iceberg that collided with the Titanic was land-based ice that dislodged from a glacier and fell into the sea. The properties of these two types of ice are different. In addition, vessels operating in ice-covered waters such as the Arctic sea have an ice-breaking function or minimum ice-strengthened functions. Ships operating on transatlantic routes including the eastern coast of Canada do not necessarily require ice-strengthened functions. Hundreds to thousands of icebergs are discovered each year near the area where the Titanic sank. In this study, the status of ship-iceberg collision accidents was investigated to provide useful information to researchers, and the physical and mechanical characteristics of icebergs were investigated and summarized.

It is prospected that commercialization of the Arctic route come to faster than an anticipation due to acceleration of the melting of Arctic ice as a result of global warmness and etc. Since 1979 from the start of the satellite observation, the ice areas of the Arctic ocean came to decrease about 40 % in summer season For the commercial use of the Arctic route, it must be settled some problems including the navigation for the vessels in the EEZ of the related nations before considering about economic basis. It is also needed to build special ships which satisfy to the condition of the Arctic climate for the technical factors of ship handling and should be carried out completion of the special educational program to be approved for the seamen through the cooperation with the coastal nations. The information system for the Arctic route should be developed.

The need for ice-breaking research ships is growing as interest in the Arctic grows. In Korea the 7,500 ton ship Araon, launched in 2009, is the only icebreaker, and difficulty remains when conducting research at the North and South Pole. Thus, the Ministry of Maritime Affairs and Fisheries is pushing for the construction of a second icebreaker, and an economic valuation of a second icebreaker is needed. Such a study will help reduce controversy about the construction of a second icebreaker and help ensure reasonable decisions. The economic benefits of a second icebreaker were calculated using a contingent valuation method. In this study, a Bayesian Approach was applied, in contrast to previous methodology utilizing the maximum likelihood estimation method. According to this analysis, the average WTP per household was estimated at 1,999 won per year, and the total benefit from the construction of a second icebreaker was estimated at 373.9 billion won per year.
