The PyHum library
In May-June 2020 two early transits through the Northern Sea Route to the east were made by LNG carriers «Christophe de Margerie» and «Vladimir Voronin». The first voyage was accompanied by the nuclear icebreaker «Yamal» all the way down, the second voyage «Vladimir Voronin» covered independently. In this paper, on the example of the pair «Christophe de Margerie» and «Vladimir Voronin» and one more pair «Georgy Brusilov» and «Vladimir Rusanov», followed the pioneer tankers a month later, it was analyzed two types of navigation: independent and with an icebreaker escort. The results of the analysis did not reveal sufficient differences in time and velocity of tankers, navigating independently or under icebreaker escort in those ice conditions, which had developed by the beginning of summer navigational season.The article presents the results of using the PyHum open source library for decoding and analyzing data received from Humminbird sonars. The structure of the code, functionality, as well as the advantages and disadvantages of this library in comparison with proprietary software are considered. As a result of the work done, we came to the conclusion that the PyHum library is a convenient and functional tool for data analysis, while the proprietary software has limited functionality. PyHum is open source to extend the functionality of this library. In the near future, we plan to rewrite the code of this library in Python 3, since support for Python 2 is currently discontinued.
