Abstract:

To address the limitations of evaluating the emergency response capability of port ships for oil spills in a single stage and reasonably allocate resources, the cloud gravity center evaluation method was adopted to evaluate the comprehensive emergency response capability of port ships for oil spill. Facing the entire process of emergency preparedness, early warning, response and recovery, and referring to the theory of "man-machine-environment-management" system and international and domestic regulations, a comprehensive emergency response capability evaluation index system was established. To address the issue that the traditional evaluation indicators were not fuzzy and random, a weighted deviation degree was used to determine the transformation relationship between qualitative indicators and quantitative values. AHP was used to optimize evaluation opinions and compensate for accuracy deficiencies caused by insufficient evaluation samples. Finally, taking Shanghai Port as an example, an empirical study was conducted on the comprehensive emergency response capability evaluation of ship oil spills. The results show that the cloud gravity center evaluation method can reasonably evaluate the comprehensive emergency response capability of port ships for oil spills. This method provides a theoretical basis for improving and perfecting emergency response capability, and provides a new approach for the comprehensive emergency response capability evaluation of port ships for oil spills.
