Over 85 per cent of oil and gas resources of the Russian shelf are concentrated in the Arctic seas. As a result, it is high time and relevant to talk about oil and gas recovery in extreme conditions of the Arctic shelf. Fields development of the Arctic region is going on in extremely adverse climatic and geotechnical conditions, such as a disturbance of photoperiodicity during polar day and polar night, an altered geomagnetic activity, increased non-ionizing cosmic rays, sharp fluctuations in atmospheric pressure, a reduction of partial oxygen pressure, a polar tension syndrome, etc. Considering the above conditions, likelihood of accidents, injuries and occupational diseases of the staff is greater. In these circumstances, in order to ensure safety in the workplace, it is necessary to assess and manage occupational risks on the basis of a systematic analysis of the possible causes of occupational diseases and accidents at work, to forecast their consequences and make adequate technical and organizational decisions. Annual aggregate damage to property caused by industrial accidents, costs of liquidation of accidents and their consequences in the Russian Federation amount to tens of billions rubles. A significant share of these costs is associated with accidents at hazardous production facilities. Thus, assessment and management of occupational risks on the Arctic shelf is a priority. The author in his article considers basic provisions of the theory of occupational risk, provides an overview of current qualitative and quantitative methods of risk assessment, their advantages and disadvantages, some results of the assessment of occupational risks at marine structures on the Arctic shelf and some recommendations for the management of occupational risks taking into account the specific offshore working conditions.
