“…Wang et al [8] found that stress concentration at the base of corrosion pits can facilitate the transition of pitting corrosion from a metastable state to a stable one. In addition, atmospheric corrosion, which occurs as a result of electrochemical and other reactions between a material's surface and the constituents of the surrounding atmosphere, encompasses various forms of corrosion [9]. The utilization of GIS tools, which encompass computer software, hardware, and data, enables a wide range of functionalities such as data entry, satellite image processing, manipulation, analysis, spatial analytics, transportation management, and data presentation related to specific locations on the earth's surface [10].…”

This study integrated geographic information system (GIS) and remote sensing technology to identify areas around pipelines that are more susceptible to corrosion having the Kurdistan pipeline as a case study. Geospatial data are used to target factors such as rainfall, temperature, rivers, and minerals which increase the corrosion rate. Spatial data such as, the direction of slope, rainfall, proximity to rivers, and minerals, were collected and analyzed; maps were created for every individual factor to visualize their distribution. By overlaying these maps, regions that are at higher risk of corrosion were identified, which can be prioritized for further investigation or preventive measures. This paper’s findings are significant for oil and gas industries, including pipeline operators and designers as corrosion can lead to devastating consequences. The novelty of this study is to identify areas along the pipeline at higher risk of corrosion through the application of geospatial information systems and remote sensing. This methodology holds immense potential for industries looking to proactively prevent corrosion through the implementation of preventative maintenance, monitoring programs, and the application of protective coatings and inhibitors. The results of this research demonstrate that environmental data, GIS, and remote sensing can predict corrosion in oil pipelines, offering valuable insights for better managing corrosion risk.

Pipelines transport fluids especially petroleum and its products, the transportation process may face some problems due to the defects that can occur in the pipes. Cracks are the main defects that attack the pipes and reduce their performance. It is known that the flow around cracks in pipelines are complicated and affected by various factors, it worth to be considered before decision making on the pipeline integrity. In this study flow characteristics around the crack inside the pipeline has been investigated. The part of the pipe within the crack is the crack zone, where the flow behaviour is different with the rest of the pipe. The work carried out at the laboratory using pipes with different crack length and crude oil with known properties to observe the flow at the crack zone. Then the work theoretically analysed with computational fluid dynamics to model the flow. It is found that the fluid at the crack zone is going to be more viscous lead to accumulation and changes in the characteristics of the flow. The results revealed that the flow characteristics in cracked pipeline with no leakage depend on several factors; the size of the crack, temperature, pressure, velocity and fluid viscosity.

PurposeThe aim of this study is to employ the failure mode and effect analysis (FMEA) for risk management in cross-country pipelines, coupled with the utilization of Geographic Information System (GIS). The objective is to enhance the significance of the project, considering the potential severe consequences of pipeline failures. These consequences encompass environmental damages, loss of life and disruptions to critical services like energy and water supply. By identifying the most frequent causes of pipeline failures and developing a predictive model, the intention is to contribute toward the prevention of such incidents and minimize their impact.Design/methodology/approachA total quality management (TQM) technique for risk management; FMEA, was employed in this study integrated with GIS. Eight specific failures were identified and analyzed, exploring their effects and severity, causes and likelihood of occurrence as well as control and detection value. To find the likelihood of occurrence along the pipeline, the GIS was utilized to survey a 10 km wide area along the pipeline of 180 km long. Occurrence spatial mapping for each individual failure was generated. Subsequently, the risk priority number (RPN) was calculated for each failure, presenting the values as separate maps. By overlaying the RPN maps, a final map was generated, illustrating the areas with the highest risk along the pipeline.FindingsA modified risk management model has been developed to detect potential pipeline failures before they escalate into catastrophic events. The results provide a visual representation of the average failure modes along the pipeline, clearly highlighting regions with varying probabilities of failure based on RPN values. The RPN has been meticulously calculated across the entire pipeline, with results presented through both 2D spatial mapping and a comprehensive line graph. This comprehensive approach sets our study apart from others in the field. Our emphasis on a thorough and inclusive risk assessment methodology represents a key novelty in this research. The findings underscore the paramount importance of proactive maintenance and regular inspection practices, with these measures emerging as critical strategies for enhancing the reliability and safety of pipeline infrastructure.Research limitations/implicationsThis research study aims to enhance the safety and quality of cross-country pipelines. The main limitations of the study include the inability to consider the risks associated with the flow characteristics inside the pipeline and the exclusion of the future master plan from our analysis.Practical implicationsThe current integrated model is significant for pipeline operative companies and the oil and gas industries. These pipelines are susceptible to failures that can have alarming negative impacts on the environment, human safety and public health. It can improve the quality of risk management and elevate the safety integrity level of their pipelines. Focusing on the high-risk areas, taking action and implementing proactive measures can reduce the risk of failure and improve the safety and reliability of the pipeline system. It utilizes GIS-detailed surveying of the areas along the pipeline without the necessity of making on-site visits.Originality/valueThis study introduces a novel framework incorporating FMEA for quality risk management with advanced spatial mapping GIS software. This approach stands out as a unique contribution to the field, as prior studies have not undertaken the comprehensive task of highlighting risks along the entire pipeline using such a sophisticated methodology. This research makes a significant contribution to the field of crude oil transportation through pipelines, ultimately mitigating the risk of undesirable events.
