Forecast and emergency response of oil spill on the arctic shipping route
北极通航船舶溢油的运动数值预测与应急处置

Based on the fragile ecosystem of arctic environment, the oil spill pollution in arctic shipping route was discussed. The simulation of oil spill in ice waters was built by FLUENT. The movement characteristics of oil spill in ice waters were analyzed. The results showed that the oil adhered to the ice lower surface easily, while its diffusion area was less than that on the free sea surface at the same temperature; some oil was entrained to the ice upper surface and was further transported, which accelerated the ice melting. The pollution area caused by oil spill near the ice sheet was less than that caused by oil spill far away from the ice sheet. In view of the data, the prevention and treatment methods of oil spill were discussed. The containing combination of boom and pack ice, spraying oil dispersant in icy waters and burning oil in the sea far away from arctic continent were suggested for the arctic sea waters, which could help China to establish the environment management methods for fragile ecosystem.
