Ice sheet exerts a force on the hydraulic structures and vessels with developing and transporting hydrocarbons in the offshore waters of the Arctic causing to strengthen their design and/or provide additional measures against ice loads. The risk of ice impacts on objects of offshore oil and gas fields of the Arctic region determines the existence of the problem of ensuring the sustainability of these objects in terms of iceberg danger and ice formations. Reducing these risks involves the development of organizational and technical measures for improving the sustainability of the facilities in terms of iceberg danger through the use of international experience and development of advanced technologies to prevent dangerous effects of ice formations. Based on the fact that ice management is a specific activity that requires special effort and funds which as part of the rescue security (RS) forces at sea are missing, as well as on the basis of the fact that the system of RS at sea is not assigned to prevent accidents and to ensure the smooth operation of offshore facilities, an ice management is seen as an independent kind of ensuring the proper functioning objects of hydrocarbons production and marine transportation. The paper considers the analysis and synthesis of domestic and foreign experience of ice and iceberg management. A system of security measures for functioning marine oil and gas facilities in icy conditions on the basis of technology of preventing dangerous effects of ice formations has been worked out. It has been shown that the system of ice and iceberg management of marine objects of hydrocarbon production and marine transportation should be a practical mechanism for reducing deposits' operation risks in ice conditions. The work relates to the safe operation of mining platforms in the Arctic seas, and more particularly, to methods and means of influence on the icebergs in order to prevent collisions with fixed or floating production units.
