Drift of Sea Ice Ridges in the Pechora Sea
The drift of sea ice ridges and hits on an offshore structure with dimensions 200 m by 200 m have been studied for the Dolginskoye oil field in the Pechora Sea. The calculations were made with the computer program ICEBERG. The mean drift speed of the ice ridges was found to be 0·21 m/s with a maximu...
