Precaution advice for ice trapped ship based on DEMATEL
The sea ice trap is an important factor affecting the safety of navigation and other productive activities in this water.The study used DEMATEL to inverse the sea ice trap in the northern waters of Liaodong Bay during the winter of 2012-2022,and analysed the sea ice trap and its variation characteristics,including channels and anchorages.The results show that:tides are most severe during the bloom period,while attention should be paid to the increase of tides.It can be seen that the ice trap characteristics of the northern waters of Liaodong Bay and navigable waters can provide an important decision basis for the traffic organization and risk prevention in the waters.
