ABSTRACT
Accidental spills from oil pipelines are one of the most common man-made disasters in Russia. An accidental spill can happen from any point of a linear pipeline. Oil may spread over the ground and then, due to landform peculiarities, it may flow down to rivers. Big oil spills attract the attention of the society and usually require some urgent measures from the state authorities. Geographic information systems (GIS) are the most useful tool for solving the problems concerning the analysis of oil spill impacts on various objects. GIS methods provide the simulation of consequences of accidents, as well as the evaluation of environmental and economic damage. GIS technologies also provide developing the three-dimensional (3D) models that make possible determination of oil flow direction and spill length, as well as places of oil accumulation; position and direction of oil patch movement, considering such factors as multidirectional affection of river flow and wind on the spread of oil patch on the water surface. For example in 2006 on the territory of Yakutia was the accident of oil-pipe line Talakan – Vitim, there was chop of oil products in the river basin Peleduy, which flows into the Lena river. The purpose of the study: developing of the three-dimensional GIS model for “East Siberia – Pacific Ocean” (ESPO) oil pipeline at the territory of Yakutia (the Russian Federation) for further analysis of accidental spill consequences. Main results of the study: A 3D model of the land surface is generated using GIS technologies in order to prevent environmental risks caused by ESPO oil pipeline operations. The maps representing a negative impact of the pipeline on the neighbour areas are performed. The validity and colligation of the layers of geographical and specific data provide rapid integrated assessment of the environmental impact and the damage evaluation, as well as forecast of consequences for possible accidental situations along with environmental monitoring is also available. Maps and models developed in electronic format are recommended for forecasting and simulating of possible accidental situations at ESPO pipeline as well as for substantiation of the regional policy in order to optimise the nature management in Southern Yakutia.

Keywords: 3D GIS, oil pipelines, accidental oil spills.
