Geoinformation system use for transportations planning in water area of Northern Sea Route

[摘要] The possibilities of the geoinformation system (GIS) using for the planning of transportation and export of mineral and raw materials from the water area of the Northern Sea Route (NSR) are considered. In the near future, in 2018-2020, the number of large-capacity vessels in the western part of the NSR can be increased due to LNG (liquefied natural gas) tankers in the Yamal-LNG project to 16 units (currently only 5 gas tankers are in operation), due to the petroleum tankers in the New Port project and due to the vessels with general cargoes to the new projects - Arctic LNG and VostokUgol. The analysis of maritime transport flows in the NSR significantly differs from other kinds of transport, navigation follows the recommended routes, i.e. there are no clear boundary conditions for the movement, the parameters of the vessel's movement substantially depend on the ice situation and the hydrometeorological conditions, with which there is a constant interaction. The developed GIS for the NSR make it possible to calculate the models of potential hazard, which are taken depending on the following criteria: a distance between the vessels, courses crossing, an ice situation and hydrographic study of the navigation area. The developed model of the ship security domain is a geographic area associated with the route, course and speed of the vessel movement, for which security conditions were determined in the selected time period. The calculated analysis of the number of vessels and their average speed in the water area of the NSR along several zones during the summer and winter navigation was performed. The completed study of the movement routes of LNG tankers in the NSR water area (Kara Sea - port Sabetta) showed that the most stable traffic parameter is the average speed on the certain sections of the route, which coincides for each of the vessels. The relative values of speed, route distance, ice situation, flow complexity, etc. with the processing of AIS data of previous periods are the most logical to use for construction of a model of marine transport flows in the NSR water area.
