“…The method was tested under semi-natural conditions. In case of real freezing on the underlying surface, the freezing time also includes the time of flooding, spreading over the ice surface, the time of water cooling to the crystallization temperature, the time of solidification and the time of cooling of newly frozen ice or its cold accumulation [7][8][9][10].…”

In the domain of hydrotechnical structures, novel methods are emerging to increase ice thickness, notably in the context of ice islands. The layer-by-layer freezing process serves as a cornerstone, where freezing time determines efficacy. The article explores diverse freezing techniques, their stages, and implications. Layer-by-layer freezing entails water pouring, followed by freezing after each layer. Augmentations involve introducing ice rubble and inclined plane freezing. Sprinkling accelerates freezing through water droplet adhesion. The block method uses extracted ice blocks, creating vertical surfaces without formwork. Volumetric freezing involves pipelines and refrigerants. One method blends ice rubble with additives for versatility. Combined methods expedite construction, especially for substantial projects. These techniques cater not only to ice island creation but also to temporally reviving deteriorating structures such as moorage contractions.

“…Types of structures and methods of construction The main method of building ice islands is the method of layer-by-layer freezing. This method of building the island at the expense of the salinity of sea water reduces its strength, and the removal of the brine increases both the time and cost of construction [7][8][9].…”

The development of the regions of the Far North is currently the most important task for the extraction of the mineral resources. However, when conducting offshore drilling in the Arctic seas, the selection of appropriate hydraulic structures is crucial. Factors such as severe natural and climatic conditions, remoteness from developed areas, and the presence of permafrost soils necessitate specific considerations. This paper examines the limitations and advantages of different offshore hydraulic structures for exploration and development drilling in the Arctic. It is concluded that artificial island structures, particularly ice islands, offer the most effective solution for year-round prospecting and exploratory drilling in shallow Arctic shelf zones. Ice islands provide increased resistance to ice loads, lower costs, and minimal environmental impact. However, their usage is restricted to the winter period, as they melt or collapse during the summer. Additionally, ice islands cannot be converted into production platforms if a commercial deposit is discovered. Understanding these limitations and advantages is crucial for successful offshore drilling operations in the challenging Arctic environment.

“…These harbors provide essential infrastructure for transporting goods and commodities to and from the Arctic, connecting remote communities to global markets and facilitating international trade. Moreover, Arctic harbors serve as hubs for scientific research and exploration, enabling scientists and researchers to study climate change, biodiversity, and environmental dynamics in one of the world's most extreme environments [8][9][10][11][12]. The strategic importance of Arctic harbors is further underscored by the melting of Arctic Sea ice, which has opened up new shipping routes and opportunities for economic development in the region.…”

Arctic harbors serve as crucial gateways to economic development and scientific exploration in the Arctic region, yet they face unique challenges stemming from environmental, social, and cultural factors. This article provides a comprehensive analysis of the multifaceted dimensions of Arctic harbor development, exploring the economic importance, technological innovations, environmental challenges, and social and cultural considerations shaping the future of Arctic harbors. We highlight the significance of sustainable development principles in guiding harbor planning and management, emphasizing the importance of integrating indigenous perspectives, fostering community engagement, and embracing innovative technologies to achieve long-term resilience and well-being in the Arctic. By navigating the complexities of Arctic harbor development with foresight, collaboration, and a commitment to sustainability, we can chart a course toward a more prosperous, resilient, and inclusive Arctic future.
