Davis Strait Route Planning Based on AIRSS and Artificial Potential Field Method
The complex sea ice conditions in the Arctic region seriously affect the navigabili-ty of Davis Strait,and ships with different ice classes face different navigational risks when navigating in waters with different ice conditions.Based on the ice number(IN)calculated by the Arctic Ice Making Navigation System(AIRSS)and artificial potential field method,combined with the information of sea ice density and growth stage in Davis Strait,this pa-per completed the quantification of navigation risk in Davis Strait,and calculated the risk index of Davis Strait region.Combined with the artificial potential field method,the accessi-ble and supervised area is regarded as the repulsive area,while the strait navigation destina-tion is regarded as the attractive area.The comprehensive sea ice risk of the strait is evalu-ated according to the risk grade and ice number.Thus,the shortest route avoiding/to avoid the high-risk sea ice area in the Davis Strait region is generated,which improves the safe-ty and efficiency of navigation.
