Presently the most perspective hydrocarbons fields in terms of pre-explored reserves and exploitability can be listed as: deposits in the Barents Sea; deposits in the Kara Sea and Sakhalin offshore deposits in the Sea of Okhotsk (Piltun-Astohskoye, Lunskoye, Arkutun-Dagi, Chaivo etc.). Applicable construction methods and technical solutions for oil platforms are determined by ice regime in those areas. Operational use of GBS in ice-covered shelf seas within areas of intensive ice drifting appears to face a number of problems. One of those problems is ice abrasion that results in reinforcement exposure, accelerated seawater corrosion, and decrease of concrete thickness and durability. Due to dynamic ice effect, concrete surface contacting with ice is permanently abraded with consequent endurance cracks resulting in frequently accelerated concrete corrosion. This reduces concrete density and increases porosity which respectively causes lower freeze-thaw cycles resistance. Maximum abrasion depth shall be defined in order to determine protective layer thickness of GBS. Hence, the intensity of structure's material abrasion due to drifting ice has become the topical issue of the day.
