Permafrost engineering

Permafrost engineering survey is performed by the specialists of MSU Centre of Permafrost Research, which focuses on surveys in the eternally frozen grounds such as the northern part of European Russia, Western Siberia, Southern Yakutia, Transbaikalia and the Khabarovsk Territory. The specialists have acquired extensive experience in research on permafrost, engineering ecology, hydrogeology, geophysics, geodesics, cartography and applied programming.

The intellectual property owned by the specialists includes the following issues:

  • proprietary analysis software;
  • the database of permafrost survey data.

Permafrost engineering survey comprises the following types of work:

  • cryogenic engineering geological survey;
  • sampling of the rock material;
  • long-term thermometric observations;
  • geophysical works (seismic and electrical exploration, acoustic profiling);
  • preparation of the reports.

Comprehensive surveys are implemented during all design stages of linear and areal features (feasibility study and proposals, pre-investment feasibility study, working design, reconstruction, abandonment).

The «Institute of Environmental Survey, Planning and Assessment» runs trials of experimental and industrial piles by permanent load on thawed and permafrost grounds. The tests are conducted on the linear objects as well with the subsequent processing of the results and report preparation on the pile load capacity.

Experimental observations include the following types of work:

  • evaluation of freezing and cooling equipment effectiveness applied on the test fields and facilities in operation;
  • test fields operational control through implementation of geophysical research.

The key types of geoinformation support of the permafrost engineering surveys:

  • computer-based geological and permafrost mapping at any scale, applying GIS technologies;
  • production and operation of thermometric devices for temperature conditions research in the bedrocks;
  • expertise with engineering survey data and programmes of works, monitoring research, environmental impact assessment (EIA);
  • elaboration of the standard regulations on geological engineering surveys for the permafrost areas.

Permafrost engineering survey aims to accomplish the following works:

  • assessment of the harshness of environmental conditions for construction activity;
  • risk assessment of generation of dangerous cryogenic processes during the development of the territory;
  • ecological assessment of the permissible human-induced disturbance of natural environment;
  • feasibility studies of the measures taken for protection of the buildings from dangerous cryogenic processes;
  • assessment of the design decisions concerning construction of objects built on the permafrost;
  • monitoring observations of the permafrost state, spreading of the hazardous cryogenic processes and sustainability of the buildings;
  • assay of greenhouse gases and gas hydrate content in the perennially frozen grounds;
  • development of new methods of determining permafrost characteristics and prediction calculations.

The «Institute of Environmental Survey, Planning and Assessment» implements a variety of works concerning the design of buildings foundation owned by oil and gas industry, located within the perennially frozen grounds. Strict requirements with regard to industrial and environmental compliance must be applied to construction of these facilities.

High operational integrity of the survey facilities is provided by the specialists of the company. The projects in which the «Institute of Environmental Survey, Planning and Assessment» participated are presented below:

  • infrastructure development of the Chayandinskoye oil-and-gas-condensate deposit (Yakutia);
  • infrastructure development of the Kharasavey gas-condensate deposit (the Yamal-Nenets Autonomous District);
  • infrastructure development of the Vankor deposits and the connection to the main pipeline system OAO «AK Transneft» (Krasnoyarsk Territory).
