One of these scientific problems is the intellectual planning of the Arctic fleet operation at tactical level,as well as modeling its development over a long-term strategic horizon.It is no longer possible to plan an ever-increasing number of ships based on simple expert-analytical methods.The ongoing digitalization and computerization of this sphere require the development of specialized and science-based solutions.Indeed,the traffic of the Northern Sea Route(NSR),which in 2010 was about 8 MTPA(Million tons per annum),in 2020 increased to 33 MTPA,and by 2030 must reach enormous 160 MTPA.The number of large ice-going transport vessels will have to increase from the current 50 to about 200-250 ships.Therefore,the task of intelligent planning of the joint operation of ships and icebreakers is becoming one of the most urgent scientific problems.
An illustration of the practical significance of this research field is that,starting from 2017-2019,all the largest companies that operate the Arctic fleet began to create their own situation centers designed to monitor and plan the operation of ships.However,IT specialists that work on the creation of such centers are aimed mainly at developing a software infrastructure in the field of monitoring and management control.Therefore,these projects hardly ever have a research component aimed at solving the scientific problem described above.For this reason,Russia is experiencing an acute shortage of applied scientific research focused on the creation of new intelligent solutions and means of information support and planning of Arctic shipping.
Within the framework of this project,we will develop a set of new models and solve a number of scientific problems related to various subject areas and aimed at the intellectualization of the Arctic shipping,namely:
• application of combinatorial optimization methods in the tasks of Arctic fleet planning,
• stochastic spatiotemporal modeling of the dynamics of ice conditions and its application to increase the spatiotemporal resolution of deterministic climate models,
• creation of models for predicting the operation parameters of ships and caravans in ice based on analytical approaches and artificial intelligence methods,
• development of methods for direct optimization design of ice-going ships to ensure the versatility and efficiency of design solutions,
• creation of new methods for simultaneous optimization of the speed and trajectory of the vessel in ice under the uncertainty of ice parameters.
The scientific novelty of the project is due to the combination of these areas to solve the described interdisciplinary scientific problem.Theoretical and applied solutions that will be obtained within the framework of the proposed project are of a great practical value and can be implemented in the form of specialized services integrated into digital platforms for intelligent support of Arctic shipping.
Expected results:The project will result in new scientific and methodological solutions in the field of intelligent planning of Arctic fleet operation:
1.To solve the problem of a joined planning of ships and icebreakers,we will apply combinatorial optimization methods on the graph and take into account the multiple types of ships,as well as their different propulsion performance.The solutions obtained are supposed to be further used as the basis for specialized digital services that can be applied in practical tasks.
2.We will use the approaches of scenario-based stochastic spatiotemporal modeling of local ice parameters to predict the future navigational ice conditions and form typified ice maps.This task is necessary to form the scenarios of changes in the navigational ice situation in the Arctic on the horizon up to 2050,which has a direct impact on the required number of icebreakers and transport ships.
З.The project involves the creation and validation of the models to predict parameters of ship and caravan operation in ice based on the results of experiments in the ice basin,as well as the artificial intelligence methods.The importance of this problem is due to the fact that all the practical results of the Arctic fleet modeling and planning are directly related to the accuracy and adequacy of the models of ship operation in changing ice conditions.The results of work in this area are expected to be used in various scientific and practical studies on the modeling of Arctic marine transport systems.
4.In order to improve the quality of the initial design of Arctic ships and increase their energy efficiency,the we plan to develop methods for the optimization ship design analysis and create new algorithmic solutions to implement shipbuilding CAD systems of a conceptual type.The results of solving this problem will form the basis for practical solutions that are relevant for Russian shipbuilding design bureaus.
5.Within the framework of the project,we will pay special attention to the development of new methods of ice routing and improvement of previously developed solutions.The work will be carried out taking into account the experience of the authors in industrial projects.In particular,we will propose solutions for the problem of joined optimization of the trajectory and speed of the vessel on each segment.It is planned to carry out a comprehensive validation of the obtained solutions based on the full-scale data.
The described results correspond to the advanced world level of research in this area,and in terms of the practical component are many times greater than similar foreign developments.This is due to the fact that at present Russia is the only country that has practical experience in Arctic shipping and actively develops the solutions in the field of its intellectualization.Access to up-to-date data will be provided due to the involvement of our scientific team in industrial projects.

Ice cover is one of the main parameters describing the state of various water areas. The simplicity of calculation determines the frequency of using the indicator in research both for reading the seasonal course and interannual changes in the state of the ice cover and for verifying model data or reanalysis data. In this paper, ice cover is calculated based on five data sources. The comparison is based on satellite data from the NSIDC DAAC archives (October 26, 1978, to March 31, 2023; spatial resolution is 25 x 25 km, temporal resolution is 1 day; the data were collected by SMMR, SSM/I, and SSMI/S sensors on the DMSP program satellites, as well as the Nimbus-7 satellite and OSISAF (product code OSI-401-d; March 1, 2005, to present; spatial resolution is 10 x 10 km and temporal resolution is 1 day; the data were collected by the SSMI/S sensor on the DMSP program satellites). Model data from the international CMIP (Coupled Model Intercomparison Project) project are used for comparison and verification. Of the more than 40 models of the sixth phase of the project, two were selected that provided the necessary data and were suitable in terms of spatial and temporal resolution: MPI-ESM1-2-HR and AWI-CM-1-1-MR of the Max Planck Institute and the Alfred Wegener Institute, respectively. For all obtained coverage series, the mean, standard deviation, range, correlation intervals, trend coefficients, and standard error were estimated relative to the NSIDC series for the data intersection period of September 19, 2016 to June 31, 2023, in each of the Russian Arctic seas, as well as for the water area as a whole. Using the statistical characteristics, satellite data on ice cover were compared with the results of modeling in accordance with different socioeconomic trajectories (Shared Socioeconomic Pathways (SSPs)) for both models, the quality of ice cover modeling was assessed, and scenarios were selected that most closely matched the satellite data for both the entire Russian Arctic water area and for individual seas. Based on the optimal scenarios, possible changes in ice content were predicted.

This study examines the seasonal and interannual variability of the location and area of flaw polynyas in the Laptev Sea. It uses Arctic and Antarctic Research Institute (AARI) regional charts of ice conditions in the SIGRID-3 format covering the years from 1997 to 2023 as initial data. The analysis is based on an algorithm developed previously for calculating the frequency of occurrence of multiple vector polygon intersections. To visualize areas with a 50% polynya occurrence frequency, a series of monthly charts was produced for December through May. The annual average time series for this indicator reveals a positive trend. Seasonally, the polynyas exhibit a distinct pattern, beginning as open and extensive features in the western part of the sea. During spring, this pattern reverses, with the eastern polynyas increasing in extent as the western ones decline. This positive trend is observed in both parts of the sea throughout the season, with significant values noted during the spring months (April and May) in the western area. This is particularly important, as the polynya during this period marks the beginning of summer melting, which can have significant implications. By analyzing all polynyas polygons from the period under study (1997-2023), we identified polygons of recurring polynyas (with a 75% occurrence frequency) and stable polynyas (with a 50% occurrence frequency). It was discovered that the criterion for recurring polynyas corresponds only to a small section along the fast ice of Teresa Klavenes and Thaddeus bays. Notably, the Western New Siberian polynya has a 50% occurrence frequency and is located in a narrow strip northwest of Kotelny Island. Previous studies indicate that this section is part of the Great Siberian Polynya; however, it is evident that its development has been limited in recent decades. In contrast, the sections of the Northeastern Taimyr and Anabar-Lena polynyas are significantly larger and exhibit high occurrence frequencies. This scenario may be linked to changes in large-scale atmospheric circulation and the dominance of western circulation patterns.

The paper presents the results of a study of the morphometry of a first-year ice ridge formed in November during the drift of the "North Pole-41" station from December to August using thermal drilling and thermistor strings. The dynamics of the consolidated layer thickness include an increase in the thickness in winter-spring, continued consolidation in the first half of summer, and subsequent melting. Keel consolidation increased from 31% in early January to complete freezing in early August; the contribution of summer processes to the increase of the consolidated layer thickness during the period of its maximum development was 8%.

Landfast ice of the Laptev Sea was analyzed with the help of the previously developed effective algorithm for calculating the frequency of occurrence of an unlimited number of vector polygon intersections. Arctic and Antarctic Research Institute (AARI) electronic ice charts for 1997-2022 were used as initial data. As a result, occurrence frequency charts of fast ice distribution were obtained and analyzed. The seasonal variations and the growth of fast ice during the winter period were considered in detail; the probability was calculated and charted for each ten-day period. Interannual variability was estimated. The relation of fast ice and bathymetry were analyzed.

Production interruption caused by an unfavorable combination of weather factors have a significant impact on the integral performance of objects and systems operating outdoors, which should be properly taken into consideration in their simulation models ("digital twins"). The paper proposes a method for stochastic modeling of a random process of "weather windows" dynamics in continuous time, i.e., with an arbitrary time resolution. Discrete records of regular meteorological observations are used to identify the parameters of this continuous stochastic generator. The proposed technique makes it possible to obtain an accurate model description of the random process from indirect and incomplete measurements, provided that certain assumptions about its nature are met. Examples and prospects of using the proposed approach in simulation models of marine transport systems are considered.

The article describes the results of calculating the characteristics of ice drift in the area of port of Sabetta (Gulf of Ob, Kara Sea), observed in the summer of 2022 during the period of breaking of landfast ice. We determined ice drift with help of the maximum cross-correlation method using images obtained from a coastal radar station. The drift vector analysis was carried out using vector algebra methods. The maximum cross-correlation method was verified and the main statistical characteristics of ice drift were obtained: the mean ice drift in the area of port of Sabetta, the standard deviation of the drift were estimated, and the spectral density of the drift was calculated. It was found that the average drift vector is directed to the northwest and has a speed of up to 6 cm/s. The main variability of the drift is determined by the semidiurnal tidal component. The experience gained in the article shows the potential of using data from coastal radar stations for monitoring, calculating the regime characteristics of ice cover drift and calculating ice loads on port hydraulic structures. © 2025 by the International Society of Offshore and Polar Engineers (ISOPE).

This study presents a stochastic model for simulating landfast ice, a critical component of Arctic sea system. We developed a probabilistic approach to describe landfast ice spatial and temporal variability. The model incorporates long-term trends, seasonal cycles, and stochastic fluctuations, with its validity being substantiated by empirical data. Results reveal significant regional differences in landfast ice behavior, with western areas showing stronger trends. The proposed method offers a flexible tool for simulating landfast ice dynamics under changing climate conditions, addressing limitations of traditional deterministic models. © 2025 by the International Society of Offshore and Polar Engineers (ISOPE).
