... ABSTRACT The article discusses seasonal variability of the strength properties of ice formations typical for the Arctic offshore. Thermal states of stamukhas and ice ridges were experimentally studied in the Khatanga Bay of the Laptev Sea in 2019-2020. Maps of temperature distribution...

..., the article considers the interaction of ice formations in the form of flat ice fields and their fragments with the legs of the Jack- Up platform, and their geometric parameters (area and thickness) are determined at which the ultimate state of the marine engineering structure does not occur.

... activities and, thus, costs optimization of exploration drilling. Duration of ice-free period depends on the date of the sea clearing from the ice and on the date of the stable ice formation. Data analysis was based on historical ice maps and satellite information for a 30-year period from 1989 to 2018...

... capacity. During expeditions for ice mechanics study organized in the Kara and Laptev seas in 2014–2015 two types of large-scale experiments were carried out in order to estimate the atomic icebreaker "Yamal" (Russia) breaking effect on ice formations and to evaluate the integral physical and mechanical...

... ABSTRACT The paper presents 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 area of Franz Josef Land with the diesel icebreaker "Novorossiysk" as a part of the "Kara-Summer...

... ABSTRACT Icebergs are ice formations that confer high risks for marine activities. Drifting and entering the Arctic offshore waters, icebergs greatly influence the operational regime of hydrotechnical structures, choice of supply vessels and ice management system, etc. To track ice formations...

... This article is a sequel of the paper Krupina at al. (2009). The analysis of results of in situ experiments for definition of loads applied to the ship during interaction with various types of ice formations is presented in this paper. The experiments were conducted in the framework...

... Sea. The target was to define global ice load applied to the ship by ice formations, namely, level ice, different types of hummocks and bergy bits. To define forces applied to the ship she was equipped with 2 measuring systems based on various physical principles. The first system allowed monitoring...

..., the average monthly temperature of air in January in the north of the sea reduces down to –10°C at an absolute minimum down to –30°C. Hence, there the intensive ice formation occurs. That complicates winter navigation, fishing, and also production of mineral resources and hydrocarbons from a seabed. Literary...

... ABSTRACT As it known, the ice cover renders significant abrasion effect on surface of the offshore structures, especially in the seas with the high dynamics of drift. At present oil and gas fields of Northeast Sakhalin where the drift velocity of ice formations reaches 1.5 m/s are under...

... ABSTRACT Experimental results on hydrate and ice formation conditions in the pores of sandy sediments during temperature cycles are presented. To better understand how hydrate accumulates in sandy sediments, we measured the accumulation of CH4 and CO2 hydrate and ice in sandy sediments under...
