On the relationship between sea ice deformation and ship damages in the Gulf of Finland in winter 2003

Abstract

Sea ice ridges and other types of deformed ice are the main obstacles for the winter navigation. During the severe winter 2002/2003, about 60% of the ship hull damages, registered in the Baltic Sea, occurred in the Gulf of Finland. We have analysed ice deformation features, derived from the HELMI sea ice model in relation to two ship damages that occurred in the Gulf of Finland this winter. The damages happened close to the high growth rate area of deformed ice at the interface of different ice conditions with notable ice thickness gradients. It is concluded that the rate of ridged ice production is an indicator of the compression of the ice pack and a potential indicator of ice-induced danger to shipping.

Machine Learning-Based Image Processing for Ice Concentration during Chukchi and Beaufort Sea Trials

“…In particular, from a resource development perspective, the Arctic contains more than 13% of the world's undiscovered oil, 30% of gas, and several times more hydrates than gas [3]. Since various ice conditions affect the working performance of offshore structures [4][5][6], it is considered important to develop an accurate ice concentration model for the development of the Arctic route and ensure safe and efficient navigation in the Arctic Ocean. Silva et al [7] predicted the sea ice concentration using a mesoscale eddy-resolving ice ocean coupled model to reduce an uncertainty in the narrow region prediction of a general numerical model.…”
