IMPROVEMENT OF MATHEMATICAL MODEL OF OIL SPOT INTERACTION WITH MARINE ENVIRONMENT
For modern person the resource requirement continue to be very relevant, and among the variety of them oil is allocated. It is an important strategic resource that determines the economic and political sentiment of the many nations in the world. But neglect of safety issues in its development, transportation, conversion and other production processes jeopardizes the environment quality, since when spilled due to a multicomponent structure, oil changes its physicochemical properties significantly. A significant mark is the environment itself, especially characterized by considerable dynamic parameters. So, despite sufficient experience in the field of studying the oil behavior in the marine environment and the patterns established by this, there is still no reliable model that allows to obtain unambiguous quantitative parameters determining all oil conversion processes in the sea water area. The many uncertainties that characterize the risk concept make it necessary to adjust existing models to predict the oil spill behavior. In accordance this in the article the issues of improvement of mathematical model of oil spot natural dispersion process, its spatial movement in marine environment under action of external forces, as well as drift of particles suspended in water column under the influence of hydrodynamic factors are considered. Taking into account these features, more accurate results close to reality are obtained, which contribute to more effective decision making when planning the respond to emergencies caused by oil and oil products spills.
