Objective: To determine the main approaches to safety management of high-speed railway transport on the basis of modern international and domestic practices in the specified sphere. Methods: Analysis methods of security risks on railway transport were considered in accordance with modern international standards of management of interconnected indices’ complex, which include reliability, availability, maintainability and safety and cost (Life Cycle Cost – LCC) at all stages of transportation systems’ life cycle: EN 50126 (IEC 62278), EN 50128 (IEC 62279), EN 50129 (IEC 62425) and IEC 60300-3-3. Results: The main approaches to safety measures of high-speed railway lines (VSM) were detected. The former involve using a lifecycle concept of engineering systems and facilities, management methodology of RAMS/LCC interconnected indices’ complex at all stages of a life cycle, wide application of the process approach and the tools of quality and safety management systems, development and implementation of technological maturity assessment methodology for security management activities, as well as object-oriented and coherent improvement of regulatory base, the systems of administrative and control and permission authorities, technical and technological development, management of external, inland and allocated risks under market relations. Practical importance: The examined approaches of VSM safety control make it possible to obtain a priori estimates of safety control processes and thus determine the achieved level of safety together with the levels of technological maturity of railway organizations’ processes.

In article regulatory framework of maglev are considered, the international experience is analysed and conclusions for Russian practice are drawn. Modern management methods of safety of transport systems are based on principles of advance to occurrence of dangerous events. These principles include: - application of forecasting methods (aprioristic estimation methods) at an estimation of safety and substantiation of safety measures - a principle of «the new approach»; - estimation of safety taking into account risk from action of casual and systematic failures; - safety management in a complex with management of reliability, availability, maintainability, material support and life cycle cost. Necessity of application of «the new approach» to railway safety, including the high-speed railways, formally has been established by the Railway Safety Directive 2004/49/EC. This Directive orders to use: - analysis and management of risk at all life cycle stages of the technical systems participating in formation of traffic service, and at early stages of life cycle are made look-ahead estimations of risks which are compared with admissible values of risk; - common safety targets, common safety indicators and common safety methods on all space of the European Union; - common approaches to certification of safety and the harmonised supervision bodies; - common typical safety management system, based on ISO 9001principles. For activity expansion on performance of Railway Safety Directive of the European Committee for Electrotechnical Standardization CENELEC have been developed and now frame standards EN 50126, EN 50128, EN 50129 are applied.

AbstractThis study focuses on the evaluation of the benefits and ecological costs that occur in the life cycle of a wind power plant. The study constitutes an attempt to expand upon previously conducted research on the analysis of costs and benefits in the stages of production, operation and post-consumer management of wind turbines. The aim of the study adopted research methodology, analysis and assessment of the benefits and environmental impacts of the Vestas V90/105m 2 MW wind turbine throughout its life cycle. Original assessment indicators of the benefits and ecological costs occurring throughout a wind power plant’s life cycle for environmental safety management, were proposed and verified.

Abstract The article presents the FMEA method application, which is relevant in verification of design of two separated railway signalling systems. The efficiency of the method at the stage of the design was discussed. The method was identified as an important element of safety management process and as safety analysis method, which is included in the Safety Case and is applied for the sake of safety arguments and its assessment. Safety process management comprises several phases and appropriate actions, linked with each other in the way to create safety life cycle consistent with system life cycle. The safety case is a set of documents demonstrating that the product is compliant with defined safety requirements including analysis that indicates the correctness of the design and the correct reaction of the system to the failures, with appropriate and requested fail-safe reaction. It is necessary that railway signalling system should fulfil SIL4 requirement and remain safe in case of occurrence any kind of single failure of the equipment considered as possible.
