| Summary: | Abstract Based on the classification results of marine structure accidents induced by sea ice, the risk assessment index system of sea ice disasters was established. The possibility coefficient of risks was proposed based on risk factors of sea ice disasters, including sea ice conditions, ice risk status, ice resistance in the design phase, the current defense ability in the operation phase, and management behaviors in the freezing period. The severity index should be determined according to the affected scope, the distribution of affected personnel, and the monitoring ability in emergency. According to the case study and expert evaluation method, the scores and levels of sea ice disaster risk assessment indices were determined. Finally, the sea ice disaster risks of two offshore oil platforms and a coastal nuclear power plant were assessed.
