The issues of using the geographical information system of the Northern sea route to monitor the movement of tankers intended for the transportation of liquid natural gas in waters of Arctic seas are considered. The examples confirming of begin the actual realization of the Complex project plan about development of Northern sea route are given. Particular attention is paid to the description of marine Arctic transport projects for the transportation of hydrocarbons by large-tonnage tankers and gas tankers. The list of the most significant transitions that were performed in the water area of the Northern sea route by large-tonnage tankers from winter 2017 to 2018 is given. Based on the above list of implemented transport projects and analysis of the prospects for commercial use of the Northern sea route, a list of trends in the use of large-tonnage tankers in the waters of the Arctic seas has been formed. It is noted that the presented work is a continuation of the research on the development and use of geographical information systems for the analysis of the parameters of the movement of ships in the waters of the Northern sea route and the characteristics of marine Arctic transport flows in General in different navigation periods, in which the author was directly involved since 2016. An analytical review of scientific publications on the use of geographical information systems in the regulation of the movement of tankers, which were used for the export of hydrocarbons from offshore fields in the Gulf of Mexico, is presented. A comparative evaluation of the criteria used in the regulation of the movement of ships in the non-freezing seas and in the waters of the Northern sea route is carried out. The necessity of collecting and analyzing the actual data on the characteristics of the movement of large-tonnage tankers used for the transportation of liquefied natural gas in the waters of the Northern sea route in an experimental mode and during the first regular passage is substantiated. The paper presents the actual data and their analysis about speed regimes of five Yamalmax class tankers while performing their independent navigation in the waters of the Northern sea route in the period from November 2017 to March 2018. The direction of further use of the received data is defined.

Nowadays, both in the Russian Federation and in foreign countries, the use of global navigation satellite systems (GNSS) for solving various applied problems is an extremely popular solution. Taking into account the current level of development of satellite radio navigation systems, ordinary users have been able to determine their position with a sufficiently high accuracy. However, some tasks require the use of high-precision equipment of geodetic class. Such equipment allows obtaining navigation solutions with an accuracy of better than 10 cm. Unfortunately, the cost of navigation-class navigation equipment is extremely high. Specialists working in the field of satellite navigation are particularly interested in the possibility of using mass-produced GNSS modules to obtain high-precision navigation solutions. In this paper, the possibility of such an application will be considered, taking into account the results of laboratory tests of a mass-produced navigation module.

The development of information modeling technologies for construction offers new tasks to develop operational models for facilities, which are locate in most difficult conditions, here an important example is the marine Arctic ports. To build a life cycle model, reliable long-time information about hydrometeorological conditions for the selected port facility is needed. It also requires accurate data on the design and past loads. We offer the basic methods for obtaining the initial data for operation BIM model subject to the technical and design documentation are absent, what is a common practice for old facilities. The main theses for development of information BIM model for a marine port’s facilities exploitation in the Arctic are proposed in this paper. At the initial stage of description of the structure life cycle, it is necessary to develop an electronic passport of the facility that would contain the basic geometric characteristics of the structures elements, the information about the applied materials and their physical and mechanical properties, coordinates of the plan and deformation geodetic network in the digital format. At the next stage, it is necessary to provide automated monitoring for measuring the main parameters of loads, deformations and climatic conditions, which in combination ensure the safety of the port’s structures.
