description: The object of the study was accidents on main oil pipelines. The subject of the study was the modeling of the processes of spreading an oil spill formed during an accident on a main oil pipeline. The purpose of the work is to develop, based on existing mathematical models of computational fluid dynamics, a methodology for modeling the oil spill process in case of accidents on main oil pipelines. To achieve the goal of the work, the following tasks were solved: 1. The technical documentation of hazardous production facilities and regulatory legal acts were analyzed in order to study existing methods of modeling oil spills during accidents. The shortcomings in the studied methods are identified. 2. Scientific works in risk management domain were analyzed in order to find alternative ways of accident modeling, risk assessment and management, in order to justify the need to develop a new methodology. 3. The physical processes occurring during emergency oil spills were described using a mathematical apparatus. 4. A computational algorithm necessary for modeling an accidental oil spill has been formed and the architecture of a software package implementing the specified algorithm has been developed. 5. Modeling of accidents with oil spill on the main pipeline using the developed software package has been conducted. The research methods used to solve the tasks set in the work included analysis, comparison, abstraction, formalization and modeling. The list of information technologies used included: the official Internet portal of legal information (pravo.gov.ru ), Polytechnic Electronic Library (elib.spbstu.ru 7 ), scientific electronic library (www.elibrary.ru ), Microsoft Visio, Microsoft Excel, Microsoft Visual Studio. As a result, a software package for emergency oil spills modeling was developed. Using the developed software, accidents on the main pipeline and on the oil storage tank were simulated. Modeling of accidents on the oil pipeline was conducted by various experiments with different parameters. Modeling of accidents on the reservoir was conducted by two experiments: leakage through the hole and quasi-instantaneous depressurization. The results of this work can be used in the development of different obligatory technical documents specifically developed for needs of industrial safety and due the expertise of this documents.
