Opis:: In the article the impact of the structure of pipeline transportation systems on the efficiency of their operation is examined. It is shown that, depending on the assumed structure, transport systems can be characterized by different performance characteristics. It is established that the structure of the system influences the development of the aging process and decrease system performance. Recommendations on the choice of the structure of systems that can be used at the design stage are given.

Opis:: The estimation of leak and break frequencies in piping systems is part of the probabilistic safety assessment of technical plants. In this paper, the statistical method based on the evaluation of the German operational experience for piping systems with different diameters is described because an earlier estimation has been updated and extended introducing new methodical aspects and data. Major point is the inclusion of structure reliability models based on fracture mechanics calculation procedures. As an example of application the statistical estimation method for leak and break frequencies of piping systems with a nominal diameter of 50 mm (the volume control system of a German pressurized water reactor) was updated. Moreover, the evaluation of the operational experience was extended to 341 years with respect to cracks, leaks and breaks in the volume control system of German pressurized water reactors (PWR). Using the actual data base, new calculations of leak and break frequencies have been performed and the results have been compared with the previous values.

There are distinguished three different processes for the corresponding piping operating area. Further, using identified parameters of the piping operation process and the piping operating area climate-weather change processes, there are determined the unknown parameters of those processes. Namely, there are determined the probabilities of the processes staying at the initial states, the probabilities of the transitions between the states and the mean values of the processes' conditional sojourn times at particular states. Finally, there are predicted the main characteristics of the piping operation process related to climate-weather change processes at the distinguished operating area.

Opis:: The paper explores the mathematical and computer modeling of complex technical systems related to their operation processes. The complex technical system with the reliability structure and components’ reliability parameters changing at the various operation states is defined. The selected system operation process parameters and the hypothetical distribution functions of the conditional sojourn times at the operation states are defined and identified. The reliability functions of the multistate system and components are introduced and their parameters are identified. The Monte Carlo simulation method is proposed to the complex system reliability evaluation. Moreover, the proposed theoretical and simulation tools are supported with the practical application to the multi-state port oil piping transportation system reliability analysis.

Opis:: A new approach to safety investigations of multistate complex systems with dependent components at variable operation conditions called critical infrastructures is proposed. The safety function of the critical infrastructure system is defined and determined for an exemplary “m out of l” critical infrastructure. In the developed model, it is assumed that the system components have the multistate exponential safety functions with interdependent departures rates from the subsets of the safety states. The approach is adapted to safety prediction of oil piping transportation system operating at a maritime port.

Opis:: The problem of finding the parameters of the gas transmission system in terms of its operations under unsteady operating modes are considered. We show mathematical models of gas flows in the basic facilities in the system with a complicated piping diagram. The solution is built to solve a system of partial differentia equations with the finite element method of large dimension with boundary conditions, some of which are designed in the process of solving the system of equations. This is due to the provision of technical and technological constraints on the pressure of the controlled points of the system. On the resistance to finding a solution significantly affects a step of the time coordinate. The proposed algorithm in the editing process of flow diagrams provides an increase in stability of solving systems of equations, and significantly reduces the time for the simulation.
