The paper presents the results of experimental iceberg towing operations performed in ice fields during the early stages of ice formation. Experiments were conducted in October 2017 in the Kara sea. Towing techniques and scope of works are described. Limitations of iceberg towing under different ice conditions are determined and discussed. Technological features of towing operations within negative air temperatures and the presence of sea ice are also highlighted. Optimal tactics for towing icebergs of different sizes under conditions of early ice formation are proposed. A one-day non-stop experiment towing an extra-long iceberg for 50 miles in ice conditions is described.
Iceberg towing experiments in ice conditions performed during the “Kara-Summer-2017” expedition, as far as the authors know, are unique and first in the world in their real-scale tests with monitoring of all parameters.
Numerical simulations and ice basin modeling (Eik and Marchenko, 2010; Yulmetov and Loset, 2017) show a fundamental possibility of iceberg towing in ice conditions, as well as its significant difficulties. It is noted that a lack of information about the actual behavior of the iceberg and towing system under the influence of ice cover seriously complicates interpretations of the obtained results (McClintock et al., 2002; Randell et al., 2009; PAL, 2010). This work describes experiments of iceberg towing under conditions of newly formed ice as well as ice effects and thus gives unique data for further research.
