Evaluation of the geoecological and fire situation in case of the oil spillage on the water surface

Abstract

Abstract The work provides an assessment of the geoecological situation during an oil spill on the water surface. The modeling of the process of oil burning on the water surface is carried out, and also a model for estimating the oil burning time during depressurization of the underwater passage of the main oil pipeline is proposed. The assessment of individual and social risk in case of ignition of an oil spill as a result of depressurization of the underwater crossing of the main oil pipeline is given. The fire risk assessment was carried out under the condition of a guillotine rupture of the underwater pipeline, since, despite the lowest frequency of this type of depressurization, the levels of exposure to damaging factors, due to the largest volume of oil spills, will be maximum and will make the main contribution to the magnitude of the fire risk. When forecasting an emergency, a model of the spread of an oil slick along the water surface of a watercourse was developed, which takes into account the wind speed and the speed of the river flow.
