The area around the waterline, where contact with the ice is particularly severe, is called the ice belt, and thicker shell plates are used around the entire periphery than other areas. Special low-temperature steel that can withstand temperatures as low as -50°C is used for the structural materials.

*Some of the terminology that refers to "ice belt" is listed below.
