Ice freezing for hydrotechnical structures

Abstract

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.

Sustainable development and challenges in Arctic harbors

“…Coastal erosion further exacerbates this issue, as it undermines the integrity of harbor facilities and threatens to engulf them in the sea. These environmental changes necessitate the development of resilient infrastructure designs that can withstand shifting ground conditions and rising sea levels [22][23][24][25][26][27][28].…”

Arctic waters: port Sabetta development

“…Infrastructure investments not only enhance connectivity and accessibility in the region but also catalyze economic development by attracting investment, facilitating trade, and promoting tourism. Improved infrastructure also strengthens the resilience of local communities to natural disasters and extreme weather events, mitigating socio-economic vulnerabilities in the Arctic environment [26][27][28][29][30][31][32][33].…”
