Abstract: The problem of reliability ensuring of marine facilities in the conditions of interaction with the ice is actual. Existing standards of reliability indirectly reflect the rules of Russian Maritime Register. The corrosion wear additives of shell plating and ice strake is important. Increase additives leads to an increase in the weight and cost of the ice reinforcement designs. In this paper, there are shortcomings in standardization of additives for corrosive wear for icebreakers and ice navigation vessels. The icebreaker service life may exceed 50 years. Corresponding additives for corrosion wear may exceed 25 millimeters. It is shown that project surcharges for corrosive wear should be related to wear rates in operation. It is also advisable to take into account the relationship between the rate of corrosion and ice pressures. The issue of development of norms for surcharges for corrosive wear is considered in the work. First of all, this is accounting for protective coatings. A scheme for harmonizing the norms for surcharges of corrosive wear depending on the ice category for icebreakers, tugboats and other vessels is proposed. A way of differentiating surcharges for corrosive wear in different areas of the hull is proposed. Questions of planning and monitoring the life cycle of vessels are considered. The prospect of changing the ice category of the vessel during the life cycle is noted. Proposals can be used to develop the Russian classification system.
