Natural nanomaterials as a basic for improving the environmental safety of transport systems

The economic crisis being overcome by the Russian economy, on the one hand, combined with the inevitable globalisation processes, on the other hand, brings to the forefront the economic efficiency of technical processes associated with environmental safety and the possibility of introduction into the world system. One example of effective use of innovative technologies in the interaction of transport systems in the world is the piggyback transportation. Aim: The author has conducted the analysis of international experience of the organisation of the piggyback transportation in order to identify technological solutions suitable for efficient use in the Russian market of intermodal transportation. Methods: To assess the efficiency of different technological systems, the author uses comparative analysis methods, inductive reasoning, system approach method. The author has also synthesised the world experience in the organisation of the piggyback transportation. Result: The results of the analysis have revealed that the current economic situation in Russia allows the evaluation of innovative transport systems in the first place in terms of the possibility of rapid return, which draws attention to the most economical technologies. In this regard, the use of the rolling highway and Lift-on – Lift-off (Lo-Lo) piggyback systems seems to be the most rational at this stage. Conclusion: Since 1990s Russia has made a number of attempts to organise regular piggyback service on certain routes. However, due to the lack of demand for this type of services in the Russian market at the moment, investing in the development of piggyback technology involves high risks. The experience of other countries shows that regardless of the chosen technology, stimulating the demand for innovative "green technologies" is not possible without the participation of governmental bodies. At the same time, the creation of the necessary methodological framework for the organisation of piggyback transportation in Russia is possible by virtue studying the multifaceted world practice of piggyback technology operation in the world.

Economic Ties

New economy - an innovative economy - forms new challenges and new solutions in all spheres of human activity. A key feature of the new economic ties is their global nature. Transport systems based on existing technologies cannot provide the necessary growth of new economic ties and the effective provision of the existing business. New transport systems based on new technologies for transporting goods and passengers in compliance with the principles of energy and financial efficiency, as well as environmental safety, create the foundation for sustainable development of countries and regions, including improving the quality of life of the population and human potential. The rapid speed economic is been formed for nowadays commercial transportation communication. And a realization of any transport project has always tight connection and mutually conditioned with another project type energetics. So, the problem of energy efficiency and energy supply becomes a key factor of a choice of the most energy efficiency of a base system in any transport complex!

Pipeline Monitoring

Environmental safety issues are of particular importance when we design and operate underwater transport systems. To ensure the transport systems function safely, special systems to monitor their condition are being created. Underwater pipeline monitoring systems should continuously operate to detect and prevent emergency and pre-emergency situations in a timely manner. The purpose of this article is to demonstrate the possibility of using a mathematical model of a k-out-of-n system to support decision-making in the preventive maintenance of an unmanned underwater vehicle to monitor the condition of a subsea pipeline. The novelty and feature of this study are that we investigate a strategy of preventive maintenance for a model of a k-out-of-n system, where failures depend not only on the number but also on the location of the failed components in the system. The method to solve this problem, based on the distribution of the members of the variational series of the failing components, is also new. Since the distributions of the system component lifetimes are usually known with an accuracy of only one or two moments, we paid special attention to how sensitive the decision making about preventive maintenance is to the shape of the distributions. Numerical examples are conducted in order to support the theoretical investigations of the paper. The results of the study are applied to specific equipment to monitor the state of the outer surface of the pipeline.
