Problem solving of the ice navigation depends not only on ships operation safety in ice, but also the safety of operation of freezing harbors. Such questions are particularly important for navigation in Russia, as the number of the icebreakers reduces and increases the number of foreign ships calling at these harbors. In 2012 the Russian Maritime Register of Shipping has introduced the technical procedures of vessels ice survey and the assigning of the Ice Navigation Certificates. Requires the accumulation of the experience and the development of appropriate techniques to determine the most important characteristics that affect the ice navigation properties, as well as, the criteria of these properties. This study reports on the methodological approaches to assess the safety of navigation in broken ice and the ice-going properties of vessels in autonomous navigation, and in following the icebreaker in the convoy. One of the most important characteristics related to safety of ice navigation is the vessel velocity. Changing the vessel operation parameters affecting the ice-going property serve: the displacement of the vessel with cargo and characteristics of the structures technical condition and the shell plating. Evaluation of ship ice-going properties is determined depending on the thickness of the ice, the density of ice (cohesion) and compression. Safety and efficiency of ships navigation in ice depends not only on the sea ice conditions, but to a large extent on the design characteristics of ship and it’s particulars. A key issue is the definition of the optimality criterion based on the concepts of ship’s economic efficiency and on the evaluation of design constraints, in other words, the input data to determine the design characteristics of the ship. It should be noted that the effectiveness and safety of the vessels for operation in ice, to a large extent linked, and in assessing the effectiveness of the ship with the economic criteria required to take into account the additional costs required to provide a given level of safety of the ship in the ice conditions that influence on the value of the economic effectiveness criterion.
Key words: merchant ship; ice navigation; technical condition; ice capture; running property; hull strength; navigation safety; effectiveness criterion; Ice Navigation Certificate.

In the grounds of the theory of ship design is the systematic approach according to which the vessel is studied as a complex probabilistic system consisting of subsystems in the design process. At the methodological combination of subsystems a new property of the vessel arises, which is not in the individual subsystems. Typically, if the subject is the determination of the ship characteristics planned for the mass construction for shipping company fleet renewal, the concept of a systems approach leads to the conclusion that the ship is part of a more general system. The concept of a systematic approach allows determining the initial data and constraints for ship design, as well as the direction of the design process, – from the general to the specific. In determining of the characteristics of new classes of ships, to be built with the shipbuilding development programs in those jurisdictions that do not have characteristic mass shipbuilding, can occur atypical problem. Designing of those ships would be directed to meet the special requirements set depending on the characteristics of devices and special equipment planned to be installed on the vessel. For the purpose of new classes of ships designing the system concept of the levels need to be redefined. In the systematic attitude the more general object than ship of new class is not an isolated set of assets of the shipping company for the design of the vessel, planned in series production, and special equipment, which corresponds to an innovative purpose of ship, the projected ship is the general object as a total in terms of the satisfaction of the particular set of specific requirements, from a methodological sense is also more general object than ship. As examples of the merchant ships, which design can start with the separate equipment or special purpose device, can start with project constraints and special requirements include the following: tankers for liquefied natural gas (LNG-tankers), which basis of the design is the development of cargo system and equipment of cargo tanks, which constructing is the technological achievement today; icebreakers, which construction and design depends largely on the construction of power plants; various classes of ships for navigation in Arctic seas, which design is subject of navigation in ice requirements, and other classes of ships, which construction is decided by the strategy of shipbuilding industry development.
Key words: systematic approach, the design optimization, batch vessel, innovative ship, vessel subsystem, the main system, the criterion variables, parameters, initial data, constraints, characteristics of the vessel, the vessel particulars, comparability of options.

The electrochemical and mechanical properties of the coatings whish are formed on low carbon steel St3 at different modes of anodic and cathode ac-polarization at plasma electrolyte oxidation (PEO). Anticorrosion properties of the obtained surface layers were studied with methods of electrochemical impedance spectroscopy and potentiometric polarization. The morphology, phase, elemental and chemical compositions of the coatings and its thermostability were examined. It is determined that input of cathode component into the polarizing signal at PEO causes forming of surface layers, which are more sustainable in corrosion-active environments and have improved mechanical characteristics in comparison with layers obtained at only anodic polarization. The effect of PEO-coatings on the processes of scale formation at ship heat exchangers working on sea water is shown.
Key words: corrosion, scale formation, ships power equipments, protective coatings.

The three-antenna GPS-compasses determine the position of the vessel, the parameters of the absolute velocity vector, the real course and its rate of change, as well as the angles of roll and pitch. Therefore, it became necessary to examine the possibility of using such compasses to determine vessel’s stability by the period of roll. For this purpose, the experimental observations were conducted at work compass JLR-20. The treatment was found that the accuracy of the measurement of ship rolling angles reaches 0.05 degrees.
