Simulation Results

One of the most significant systems that can be expressed by partial differential equations (PDEs) is the transmission pipeline system. To avoid the accidents that originated from oil and gas pipeline leakage, the exact location and quantity of leakage are required to be recognized. The designed goal is a leakage diagnosis based on the system model and the use of real data provided by transmission line systems. Nonlinear equations of the system have been extracted employing continuity and momentum equations. In this paper, the extended Kalman filter (EKF) is used to detect and locate the leakage and to attenuate the negative effects of measurement and process noises. Besides, a robust extended Kalman filter (REKF) is applied to compensate for the effect of parameter uncertainty. The quantity and the location of the occurred leakage are estimated along the pipeline. Simulation results show that REKF has better estimations of the leak and its location as compared with that of EKF. This filter is robust against process noise, measurement noise, parameter uncertainties, and guarantees a higher limit for the covariance of state estimation error as well. It is remarkable that simulation results are evaluated by OLGA software.

In this paper an integrated approach to a problem related to minimization of gas supplier’s reputation losses connected with accidents on a gas pipeline and disruption of gas delivery to a consumer with the help of smart contracts is stated. Nowadays analysts and methodologists of pipeline companies perform assessment of expected and actual material expenses at an accident on GTS objects. Account and analytics of reputation losses either isn’t conducted in all, or is implemented in the frame of separate business processes which aren’t integrated into processes of enterprise budget’s management and planning. Such situation is disconcertingly. In the era of globalization the cost of a company and its business reputation depends significantly on the attitude towards it in society. In Europe and USA the major oil and gas companies invest huge money in increasing of their positive image in the eyes of population. Any significant accident which has happened in unforeseen time and unsuccessful place can completely destroy reputation of any company. Modern corporate IT-decisions allow unite a number of data flows in the uniform analytical module now. Information collected in such modules in Gazprom PJSC helps to solve optimizing problems both within planning of material inputs, and within accounting of reputation expenses. In this work a theoretical model for assessment of reputation losses at an accident on a linear part of a gas transmission system (GTS) of Gazprom PJSC is given. Modern theoretical models for definition of function of supplier’s reputation losses have been used. The review of possible application for SAP decisions and Blockchain technology in current business processes of Gazprom JSC in the frame of the problem solution is given. For a clear understanding how to integrate this decision into existing business processes the graphic description of the decision work scheme is given. The principles of this approach can be applied not only in working processes of Gazprom PJSC, but also adapted according to other pipeline companies’ needs. Possible fast introduction of cryptoruble in Russia can offer new prospects for mass introduction of this tool in the context of smart contracts.

Process Safety Management (PSM) is an integrated approach to managing loss prevention. At Enbridge, as with many organizations, several PSM elements of practice have been implemented with different levels of rigor, maturity and/or alignment with best practices. This paper presents Enbridge Liquid Pipelines’ approach to assess a strategy to adopt a formal PSM system. A description of the current regulation framework for PSM and the drivers for adoption are presented to explain the considerations during the scoping and design of a PSM system for an international oil and gas pipeline system that operates across numerous state and provincial boundaries, and one international border. The paper also discusses the requirements for organizational governance to ensure accountability for and ownership of individual elements of a PSM program throughout a large, geographically diverse organization such as Enbridge. Finally, a strategy to develop and potentially implement and manage PSM in a large organization such as Enbridge is proposed.

For long distance oil and gas pipeline system has the characteristics of high accident rate tending to happen in personnel job activity, this paper expounds the necessity and application steps of HAZOP (Hazard and Operability Analysis) analysis for long-distance pipeline system key operation procedure (SOP). The HAZAOP analysis of deviation, causes of deviation, consequences, existing control measures and recommending measures, make the key operating procedure safer, and also contributes to the improvement of the oil and gas pipeline system safety and fitness between operating procedures and hardware facilities. The results of application examples show that HAZOP is able to identify key operating procedure loopholes, helps enterprises optimize key operating procedures, improves the hardware facilities, and has an important role to improve the security of the key operation of oil and gas pipelines.

Raphson Method

Oil and gas pipelines are the main channel to ensure national energy security and national economic development due to the safety and efficiency of the transportation coast. To achieve an optimal state of pipeline operation in terms of safety and efficiency is the crucial important issue throughout the life cycle of a pipeline system. However, the optimization problem of the pipeline network system is a typical Mixed Integer Non-Linear Problem (MINLP) which are extremely difficult to solve. An optimal solution to keep pipeline operated in most efficient state under the premise of safe operation is given in the paper by using the dynamical programming method. Firstly, the improved Newton-Raphson method is used to solve the discrete pipeline system, and the operating parameters such as temperature, pressure and flow of any section surface in the pipeline are obtained. The fluid parameter values of the each discrete nodes can ensure the safety of the pipeline. Based on this, the total energy consumption cost is set as the objective function, and the oil and gas pipeline operation optimization model is then established, and the dynamic programming method is used to solve it, so that it can obtain the optimal solution of the current working conditions in a reasonable computational cost. The actual example shows that the energy cost of the optimized operation scheme can be reduced by 6.8% compared with the pre-optimization scheme.
