Assessment of risks of occurrence and consequences of oil spill in the area of the Cheboksary river port

Due to the significant number of oil spill incidents, spill forecasting plays an important role in developing plans for their prevention and response. In this article, the authors propose an analysis of the risk of oil pollution from ships in the region of the Cheboksary river port. The analysis was performed by determining the frequency of oil spills in the vicinity of the specified port, assessing the consequences (losses) and summarizing the estimates. At the same time, using mathematical modeling of oil spills in the region of the Cheboksary river port, the authors developed regression models for assessing damaging factors and calculated the size of the damage to the components of the environment (water, soil, air). The results of the studies performed in this work can be used in the development of measures to prevent or reduce the adverse effects of emergency situations, taking into account the natural and climatic conditions.
