The article is devoted to the current state of the problem of ship waste management. The paper deals with the problem of anthropogenic impact on water bodies and adjacent territories resulting from shipping, ship repair and industrial production. The classification of hazardous impacts of ships on the environment in accordance with Russian and international regulations. The main methods of solving the problem of ship waste that are currently used are indicated, the main equipment of engineering environmental protection is classified. Comparative analysis of Russian regulatory documents (The Rules of Russian River Register) and international regulatory documents (MARPOL) was held. The conclusion was made about more stringent requirements for emissions of polluting substances on inland waterways. The definition of operational wastes from vessels was proposed. The general trend was shown for toughening of rules and regulations for handling and disposing of ship-generated waste.

The paper estimates the impact of various factors on the oil pollution area for the purpose of solving the problems concerning forecasting during oil spills from the inland waterways vessels (on the example of the Middle Volga region). The following factors were considered: current velocity, air temperature, water temperature, volume and type of spilled oil product, wave height, river bank tortuosity, wind speed and wind direction, bank type, river width. A fractional two-level factorial plan of Box and Hunter has been developed aiming to test the significance of the studied factors. Mathematical modeling of a group of oil spill scenarios in the Middle Volga region has been carried out. It has been revealed that the volume of the spilled oil product, the wave height and the river bank tortuosity impact the oil patch area to a large extent. Based on the results obtained, the authors suggest the order for ranking factors into four groups according to the degree of impact on the oil patch area, depending on the specified effect quantity: extremely significant, especially significant, highly significant and moderately significant. The research results have been applied in the working out of more than 30 object plans for the prevention and elimination of oil spills of organizations engaged in oil transportation and handling, vessel bunkering in the Middle Volga region, as well as the plan for oil spill prevention and elimination in the Volga basin of inland waterways.

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.
