The group working with ice mechanics and offshore engineering performs field, laboratory and theoretical investigations of thermo-mechanical properties of ice and ice actions on offshore and coastal structures. Fieldwork is focused on in-situ tests on ice strength performed on land fast ice, drift ice and ice ridges, monitoring of ice and icebergs drift characteristics using ice trackers, investigation of morphological characteristics of icebergs and ice ridges, monitoring of thermal changes in sea ice and ice ridges, monitoring of ice actions on fixed and floating quays located in the fjords Isfjorden and Van Mijenfjorden. Laboratory works are focused on mechanical testing of ice samples under uniaxial loading and investigation of thermo-mechanical processes in saline and fresh ice. In-situ tests are performed with original equipment designed in the Arctic Technology department in close cooperation with NTNU. Laboratory investigations are performed in the cold laboratory of UNIS. Theoretical investigations and numerical simulations are focused on the modeling of performed in-situ and laboratory tests, ice and icebergs drift, iceberg towing, ice actions on floating and fixed structures, and thermo-mechanical processes in saline ice.

Completed research projects

Sustainable Arctic Marine and Coastal Technology (SAMCoT)

Sustainable Arctic Marine and Coastal Technology (SAMCoT)

SAMCoT was a centre for research-based innovation, established by the Research Council of Norway. The research activities in SAMCoT were carried out by the host institution NTNU together with UNIS, SINTEF and 14 other partners.

SAMCoT Objectives:

  • To provide the research based knowledge necessary in order forthe industry to develop Arctic technology for the energy sector in particular and for society as a whole.
  • To specifically address the implications of the presence of ice and permafrost, as well as to produce knowledge that will ensure sustainable and safe exploration, exploitation, and transport from and within the vulnerable Arctic region.
  • To provide the foundation for further development of environmentally adapted coastal infrastructure.

UNIS professor Aleksey Marchenko was leader of the WP 1: “Collection & analysis of field data and properties”.

Safety of Industrial Development and Transportation Routes in the Arctic, 2015–2019 (SITRA)

SITRA was funded by Norwegian Centre for International cooperation in Education (SIU) via the High North Programme for 2015–2019. This SMIDA sister project expanded the collaboration in the field of Arctic Technology overseas.

UNIS and Memorial University of Newfoundland (Canada) were the main partners. Moscow Institute of Physics and Technology (MIPT), NTNU (Norway), University of Alaska Fairbanks (USA) and Dartmouth College (USA) were co-partners

UNIS professor Aleksey Marchenko was project leader of SITRA.

Experiments on waves in oil and ice, 2014–2016 (WAVES)

Experiments on waves in oil and ice, 2014–2016 (WAVES)

WAVES was hosted by the University of Oslo (UiO) and funded by the Research Council of Norway.
The project provided experimental data from the laboratory and the field, to be used to validate existing theories pertaining to wave damping caused by flexible surface covers (due to elastic surface films, oil slicks or grease ice), wave dependent fluxes of momentum and energy, wave-induced currents in the presence of flexible surface covers, for example the wave-induced drift of oil slicks or the streaming beneath sea ice caused by incoming swell.

Project leader was professor Atle Jensen (UiO). UNIS professor Aleksey Marchenko led the UNIS group.

Field studies and modelling of sea state, drift ice, ice actions and methods of icebergs management on the Arctic shelf, 2015–2017 (FIMA)

FIMA was hosted by UNIS and funded by the Research Council of Norway through the NORRUSS program (Russia and the High North/Arctic). NTNU, VNIIGAZ GASPROM and the State Oceanographic Institute (Moscow) were project partners.

Objectives:
Investigation and quantifying of physical environment in the regions of offshore development and navigational activity on the Arctic shelf; contribution to estimates of physical environmental actions on offshore structures and a reduced risk level related to operating offshore in the High North; strengthening of long-term research cooperation with leading research institutions in Russia involved in the industrial development in the High North.

UNIS professor Aleksey Marchenko was FIMA project leader.
