| Summary: | Interest to sailing in arctic zone is increasing, as due to the climatic change, the seasons when northeast and northwest passages are open enough for see transportation, are getting every year longer and longer. Some other activities like oil and gas exploration and drilling at Barents Sea require also regular sea traffic connections to be opened. Sea operations at arctic zone are challenging, because thick ice generates a high magnitude dynamic load against the hull and the propulsion units. Turning and backward sailing in thick ice field are the most critical operations, in which the steerable propulsion units are in totally different service as in the regular open sea cruising. In such operations the ice field, when guided downwards along the slope of the hull, is broken to large plates, which then are fed against the propulsion unit. The |
