A ship safe speed identifying method from risk perspectives in arctic waters

Increasingly melting of sea ice in the Arctic makes it possible for merchant ships with or without ice class to sail along the North Sea Routes, in particular during the summer seasons. However, ships sailing in the Arctic may still encounter thick (brash or level) ice in certain areas. It can chall...

Description
Summary:Increasingly melting of sea ice in the Arctic makes it possible for merchant ships with or without ice class to sail along the North Sea Routes, in particular during the summer seasons. However, ships sailing in the Arctic may still encounter thick (brash or level) ice in certain areas. It can challenge a ship's sailing safety. For safety concern, the ship speed selection is recognized as one of the leading challenges for the operators in the Arctic area. To figure out safe speed selection problem, the two most common accident scenarios- ice stuck and ship-ice collision have been analyzed. Through installing this risk analysis model, the safe speed under various ice conditions can be identified and the relevant results can provide beneficial information on speed selection for Arctic ships.
