Design of an ice-resistant structure for offshore drilling in the conditions of the Arctic

The authors of the work analyzed the existing domestic and foreign concepts of drilling rigs capable of conducting exploratory drilling in ice conditions. Architectural and structural solutions for an ice-resistant drilling platform designed for year-round exploratory drilling in the Arctic have been formed. The concept of separating the offshore drilling rig into its component parts (steel platform and reinforced concrete stand) with the possibility of their separate transportation and installation at the point of operation is proposed, the advantages of this concept are determined. A set of calculations was performed to confirm the viability of the platform, aimed at assessing the adoption of the optimal form in terms of the perception of ice loads, ensuring stability. A general approach to the selection of the minimum acceptable characteristics of the soil base, their bearing capacity for the options for operating a drilling rig without a reinforced concrete stand and with a stand is determined.
