Norwegian Sea
The Norwegian Sea is part of the Northern Sea Route for ships from European ports to Asia. The travel distance from Rotterdam to Tokyo is via the Suez Canal and only through the Norwegian Sea. Sea ice is a common problem in the Arctic seas, but ice-free conditions along the entire northern route were observed at the end of August 2008. Russia is planning to expand its offshore oil production in the Arctic, which should increase the traffic of tankers through the Norwegian Sea to markets in Europe and America; it is expected that the number of oil shipments through the northern Norwegian Sea will increase from 166 in 2002 to 615 in 2015.
