The security of the functioning systems represents, through the four specific components (security, availability, reliability and maintenance), a basic component of the processing requirement. Monitoring of all specific intrinsic and operating parameters of oil and gas pipelines can be technically detected and diagnosed by: • existing defects. • rapid and effective intervention to eliminate the damage, if they occurred. To establish the maintenance programs that can ensure the proper functioning of the oil pipelines, it is necessary to establish their technical status. The research done helps reduce the risk of oil pipeline damage.

Oil And Gas Pipelines

Pipelines have been recognized to be one of the most effective means of transportation in any oil producing state. It however has its technicalities, hence the provision of regulations and guidelines for their operation. Nigeria as an oil producing state has been operating with pipelines for many years now, but in all ramifications it has not had the best and efficient oil pipeline system. This research work was as a result of the failure of the Oil Pipelines Act and its subsidiary Regulation, Guidelines and Procedure for the Construction, Operation and Maintenance of Oil and Gas Pipelines and their Ancillary Facilities, to create for an effective pipeline operation. This research applied a doctrinal type of methodology and adopted an analytical, comparative and descriptive approach. It was found that the problem with the Nigerian Oil Pipelines Act, is that it is outdated. The Act has been in existence for more than 50 years; and because of this, it cannot meet the current needs and trends in the country. Some of the needs are: meeting up with Technological Advancements, Managerial and maintenance skills, Environmental Protection, Efficiency in transportation and Security issues. More importantly it cannot take care of the current exigenecies in the country with regard to transportation of oil. This research has offered some recommendations to improve the oil pipeline system. Some of which includes a proper creation for an effective monitoring system. This should be done by qualified personnel and also with the use of advanced technology obtainable in some countries like the US. This advanced technological monitoring system will not only report any vandalization, but will also indicate when there is need for maintenance especially pipeline corrosion. There should be more creation of oil and gas pipelines in all the cities to discourage transportation of petroleum products through tanker which over the years have been the cause of so many road accidents and fire outbreaks. There should be an improvement on the types of pipelines operated; this should include new age pipelines. These problems associated with the Oil Pipelines Act necessitated the call for its amendment.

As a well-known means for pumping crude oil with high pour point, the economic effect of a hot oil pipeline to be built will depend on such factors as pipeline capacity, pipeline length, properties of the oil to be pumped, environmental conditions along the right of way, design scheme and operation scenarios. Generally speaking, engineering-economic characteristics of oil and gas pipelines are a complete set of the economic relationships relevant to engineering factors of the pipelines, each relationship involving at least an economic index or parameter. The engineering-economic characteristics of hot oil pipelines reflect basic regularities governing the general economic effect and each economic index of the pipelines, so it is helpful understanding these characteristics for the decision-making about whether and how to build a hot oil pipeline. In some cases, for a specific hot oil pipeline project, a decision or judgment on macro level may be made only from some common engineering-economic characteristics of hot oil pipelines, without the need for the engineering design and the economic analysis of the project in detail. The frame of engineering-economic characteristics of oil and gas pipelines is outlined in this paper, and some key elements are discussed on the basis of a large amount of engineering calculation and economic analysis of virtual hot oil pipeline projects, including the optimal pipe diameter and the optimal flow velocity for a given pipeline capacity, the economic capacity limits and the economic flow velocity limits for a given pipe diameter, the economically feasible maximum pipeline length for a given pipeline capacity, and the economically feasible minimum pipeline capacity for a given pipeline length. Though the basic economic data used in our research come from China, its research results and conclusions on engineering-economic characteristics of hot oil pipelines also would be helpful for hot oil pipeline projects in other countries all over the world.

Dynamics And Vibration

In this paper, the transient motion of an intelligent Pipe Inspection Gauge (PIG) while moving across anomalies inside a typical gas/oil pipeline has been investigated. The pipeline fluid has been considered as isothermal and compressible. In addition, the pipeline itself has also been considered to be flexible. The fluid continuity and momentum equations along with the 3D dynamic equations of motion of the pig comprise a system of coupled dynamic differential equations which have been solved numerically. Pig’s position, orientation and velocity profiles as well as upstream and downstream fluid’s pressure waves are presented as simulation results which provide a better understanding of the complex behavior of pig motion through pipelines. This study has been conducted as a part of the design procedure for the Pig which is currently under construction.

Western China is rich in oil and gas resources, and many oil and gas pipelines are under construction or have been completed. However, many water-related natural hazards, such as landslides, collapses, rockfalls, and debris flows, have developed in the areas passed through by oil and gas pipelines and seriously threaten the operational safety of these pipelines. Therefore, it is urgent to carry out large-scale identification and assessment of pipeline geological hazards. At present, conventional on-site investigation, evaluation, monitoring, and early warning methods are difficult to apply for rapid identification and evaluation of pipeline geological hazards across large-scale areas. Based on this, this study takes the pipeline of Sinopec Marketing South China Branch in Yunnan Province as the research area. In this research, unmanned aerial vehicle (UAV) and photogrammetry technology were used to quickly and accurately obtain multi-phase images of an oil pipeline passing through the study area, and the images were post-processed to obtain multi-phase high-resolution, high-precision digital orthophoto maps and digital terrain models (DTMs) to identify landform changes and deformation. The focus of this research is to propose a set of technical methods for UAV point cloud filtering. The DTMs obtained based on this method can effectively identify unstable areas of oil pipelines. In addition, we have carried out numerical simulations under different motion scenarios in unstable regions, providing scientific support for future geological hazard prevention and mitigation and engineering practices in oil pipeline areas.

Abstract. Landslide disasters are one of the main risks involved with the operation of long-distance oil and gas pipelines. Because previously established disaster risk models are too subjective, this paper presents a quantitative model for regional risk assessment through an analysis of the patterns of historical landslide disasters along oil and gas pipelines. Using the Guangyuan section of the Lanzhou–Chengdu–Chongqing (LCC) long-distance multiproduct oil pipeline (82 km) in China as a case study, we successively carried out two independent assessments: a susceptibility assessment and a vulnerability assessment. We used an entropy weight method to establish a system for the vulnerability assessment, whereas a Levenberg–Marquardt back propagation (LM-BP) neural network model was used to conduct the susceptibility assessment. The risk assessment was carried out on the basis of two assessments. The first, the system of the vulnerability assessment, considered the pipeline position and the angle between the pipe and the landslide (pipeline laying environmental factors). We also used an interpolation theory to generate the standard sample matrix of the LM-BP neural network. Accordingly, a landslide susceptibility risk zoning map was obtained based on susceptibility and vulnerability assessment. The results show that about 70 % of the slopes were in high-susceptibility areas with a comparatively high landslide possibility and that the southern section of the oil pipeline in the study area was in danger. These results can be used as a guide for preventing and reducing regional hazards, establishing safe routes for both existing and new pipelines, and safely operating pipelines in the Guangyuan area and other segments of the LCC oil pipeline.

Abstract. Landslide disaster is one of the main risks involved with the operation of long-distance oil and gas pipelines. Because previously established disaster risk models are too subjective, this paper presents a quantitative model for regional risk assessment through an analysis of the laws of historical landslide disasters along oil and gas pipelines. Using the Guangyuan section of the Lanzhou–Chengdu–Chongqing (LCC) Long-Distance Products Oil Pipeline (82 km) in China as a case study, we successively carried out two independent assessments: a hazard assessment and a vulnerability assessment.
