Abstract: The article covers a methodology for the optimization of the life cycle parameters of technological equipment based on the linear dynamic programming method.
This methodology provides for setting and solving of the following tasks:
• controlling of the upgrade of existing technical systems;
• controlling of the operating equipment life cycle;
• optimizing the schedule of design and experimental work on development of radically new technical systems or certain elements of them.
In order to solve the tasks listed above the authors used mathematical statistical and probability models. The models allow defining of the necessary values of the equipment characterizing its life cycle and the application of the results to certain types of products purchased by Transneft.
According to the defined values of the life cycle of the specific modifications of several types of equipment, the need of its updating, discarding, replacement with advanced analogs is determined. In case a decision is to be made on the current modification efficiency, the defined parameters are used to identify the rational operation time period, after which the equipment should be replaced with an advanced analog. The analog development is done in accordance with the research and development schedule (further – R&D). In order to solve this task it is necessary to identify the optimal R&D cost and time for its implementation, during which the analog is made, tested and installed at production sites without any downtime and productivity decrease.

Keywords: technical systems, equipment upgrade, prospective analog, research and development schedule (R&D), principal product types (PPT), PPT list, equipment life cycle, decision making person.

Abstract: The development of construction technological approaches for accident-free operation of pipelines is a task of state importance that requires research in material science, design and technologies. The article covers the review of certain aspects of improving the performance of demountable pipelines (further – DPL), in particular, by assuring during manufacturing the reliability of their linear parts achieved by using composite materials. The shortcomings of existing metal constructions are listed. The authors define methodological approaches to creating demountable pipelines from composition materials physically based on multi-layered constructions and chemically on epoxy polymers with various hardeners. The chemical stability of the proposed materials to aggressive media confirms the possibility of their using for manufacturing lightweight DPLs for the Russian Ministry of Defense. One of the problems in developing the linear part of demountable pipelines is the cracking resistance of complex structures. Static loading might become the cause of cracks formation in fiberglass pipes. Most probable areas of thorough permeability channels in the wall are the boundary moment areas adjacent to pipe fasteners, which is experimentally proven. Decreasing the stress condition of the composition material in those areas is possible by increasing the pipe wall thickness or strength.
One of the main causes complicating the use of fiberglass pipes for dismountable pipelines is the design imperfection of joints. The rational design of joints predetermines the analysis of construction, technological and operation factors influencing their carrying capacity.
The authors give the principal tasks of further research based on the presented methodological approaches to the creation of DPLs made from composite materials.

Keywords: pipeline transport, demountable pipelines, linear part, pipeline reliability, composite materials, cracking resistance, permeability, chemical stability, static loading, construction, technological and operation factors.

Abstract: Uplift of pipelines can take place due to either thermal upheaval buckling or floatation during earthquake-induced soil liquefaction. Despite similar global uplift failure being observed in both cases, the deformation of the soil surrounding the lifted pipe differs. The use of the Particle Image Velocimetry (PIV) technique showed a wider spatial deformation mechanism occurring during the seismic uplift of the buoyant pipe in liquefied soil as compared to the localised soil movement from monotonic uplift of a pipe in full-scale and centrifuge tests. This is mainly due to the difference in soil conditions between the near and far field regions of the pipe. In the former case, cyclic response of the pipe under horizontal earthquake shaking exerts external stresses onto the adjacent liquefied soil, thereby causing soil dilation to occur near the pipe. A large difference in soil stiffness between near (less liquefied) and far field (fully liquefied) regions is therefore developed which encourages the liquefied soil at far field to fill the expanding void beneath the uplifted pipe. This is unlike the more uniform stiffness of soil at drained condition in the latter case, which thereby induces displacement of soil at near field towards the invert of the pipe.

Keywords: pipe, uplift, floatation, upheaval buckling, liquefaction, PIV

Ivan Y. Lobodenko a, Alena A. Fedorenko a

a Transneft R&D, LLC, 47a, Sevastopolskiy prospect, Moscow, 117186, Russian Federation

Abstract: The goal of the article was to improve the system for providing accident-free operation of the trunk pipelines (further - TPs) of Transeft JSC operated under difficult natural and climatic conditions. The authors faced the task to draw the composite list of hazardous natural processes and events that can have a negative impact on TPs and review the measures for protecting the pipeline facility from such consequences. In the framework of the research, such list was prepared for the factors, the protection against which is currently provided. It was also found that the actual regulatory documents do not account for a number of currently existing technical solutions for preventing the negative impact of the environment, and that the definition for certain hazardous processes does not exist. The authors have identified the processes and events the effects of which requires the development of TP sites engineering protection with the account of the geological safety threshold. Besides, they formulate a need to create a single regulatory document that sets requirements for the protective system design. The authors point out that the descriptions of engineering solutions used in related areas are also applicable to the system of trunk pipeline transport.
The article is written for the TP system engineering protection research and design specialists and also for a broad scope of specialists performing monitoring of trunk pipeline facilities technical conditions.

Keywords: trunk pipelines, engineering protection, engineering protection methods, hazardous natural processes and events, complicated engineering-geological conditions.

Abstract: The article covers the review of the existing technology of tank corner weld joint assembly. During the assembly and welding of the corner weld, deviations in the assembled walls and edge gap dimensions are visually observed, which may lead to compromised performance. The authors propose solving the corner joint precision manufacturing problems by modifying the edge construction with a reverse bend intended to guarantee minimizing of the gap to normative dimensions.
The authors present the distribution of residual welding stresses and deformations in the corner joint cross-section calculated in the ANSYS software suite using the finite elements method for the proposed and existing design implementations. The obtained results allow us to conclude that further research in the given direction is practicable for integrating of the proposed corner joint manufacturing technology in the production of tanks by sheet assembly. This, in turn, will not only increase the part’s service life significantly, but also decreases the complexity of its manufacturing under assambley conditions.

Abstract: The analysis of actions on oil and gas recovery on-site makes it possible to conclude that one of the most perspective methods is pumping of gas-liquid mixture along one pipeline by twin-screw pumps. However, the practice of the use of twin-screw pumps on-site often reveals the wrong choice of units. It leads to unreasonably high pressure in the head of the pipeline, to the elevated vibration, heating of the pump and its early breakage.
The reliability and efficiency of the system of gas-liquid mixture gathering depends on the correct definition of the system parameters and its correct design and assembly.
The cross-country terrain can have an essential impact on the movement of gas-liquid mixture in the pipeline and cause its losses. Under such conditions of transportation, it is necessary to prevent the loss of water on downhill areas (it is possible when the Froude number is not less than six) and gas on elevations.

Practice of state regulation of the subjects of natural monopolies: transition to system approach whith the account of economical growth prospects

Pavel Y. Serikov a

a Transneft, 57, Bolshaya Polyanka, Moscow, 119180, Russian Federation

Abstract: The author reviews the practice of state regulation of the subjects of natural monopolies, use of both price and administrative regulation as well as the consequences of “frozen tariffs” policy.
It is demonstrated that during the twenty-years history of the state regulation of natural monopolies its “balance point” has shifted from price methods to administrative methods. The author believes that the policy of limiting tariffs for the services of natural monopolies is leading the national economy into an “investment abyss”.
He proposes to return to the tax profit relief that the subjects of natural monopolies could use the means received for investments. Besides, it is necessary to transfer to the system regulation based on economically substantiated decisions and the balance of state interests (budget needs), subjects of natural monopolies (availability of the necessary tariff means including for investments) and service consumers (affordability of goods or services) with the account of the need to lead the national economy to the path of long-term economic growth.

Abstract: As recent as ten years ago in the Russian legal system, the possibility of concluding labor contracts based on the foreign practice of Shareholders Agreements used to cause disagreements at the level of general civil law principles governing the freedom of the implementation of non-defined contracts. Since such agreements have been and remain effective instruments for the implementation of large-scale projects (as a rule with foreign participation), the documents were signed in practice, but were subject to foreign norms and jurisdictions.
However, in 2008–2009 laws on corporations (Federal law of 12.26.1995 No 208-FZ “On joint stock companies” (further – Law No 208-FZ) and Federal law of 02.08.1998 No 14-FZ “On limited liability companies” (further – Law No 14-FZ)) were amended to allow participants of limited liability companies to conclude contracts on exercising company member rights (p. 3 article. 8 of Law No 14-FZ), and shareholders to conclude shareholder agreements (p. 32.1 of Law No ¹ 208-FZ). It looked like the aim of the new revision of the Russian Federation Civil Code (further - CC) was to unite the provisions of the laws mentioned above under the single principle of “corporate contract” (which, actually, can be concluded only in corporations) and clear up several aspects. It is quite interesting that the Civil Code and the agreement on the establishment of a corporation subject to the law on corporate agreement (although the requirements of special legislation have the priority).
In such agreement the parties (all or a part) agree on certain actions (the law does not include a full list) on exercising their corporate rights. There exist a direct prohibition regarding mentioning in the agreement the participants’ obligation to follow the instructions of the company’s governing bodies (i.e. the participants may not be subjugated to the decisions of the management) or to form governing bodies in a certain composition.
The article includes the analysis of the provisions of the Russian Federation CC on corporate agreement. The authors evaluate current requirements to the content of such contract, the composition of its parties, and the aims of its conclusion. They also point to the discrepancy of the Russian Federation CC and special normative acts on the regulation of relations between the parties of a corporate deal.
Beyond any doubt most of the changes recently introduced to the Russian Federation CC merit approval, but a number of novelties raise questions. In this respect, those norms require further elaboration and itemization at the corporate legislation level.

Keywords: shareholders’ agreement, corporate relations, shareholders’ right, corporation, corporate law, labor contract, corporate governance, source of corporate law, law-making treaty.
