Mechanical and microstructural characterization, along with optical and electronic microscopy of the fracture surface, were performed to determine the cause of the CT failure. The CT meets the requirements of minimum tensile stress, chemical composition and hardness. However, the strain (18%) was below the minimum required value (19%), which was attributed to strain hardening by the cycle of spooling and unspooling of CT. Visual inspection revealed the presence of some cracks and mechanical deformation close to the failure zone, which could have been generated during the attempts to unclog the CT. Additionally, external corrosion near the failure zone in the CT was observed. Analysis of the collapse pressure in relation to the CT ovality indicated that the collapse pressure was significantly affected by ovality, and as the ovality increased, the collapse pressure decreased noticeably. Different collapse modes are obtained and discussed. The effects of the ovality on the collapse pressure are discussed. The collapse responses of CT subjected to external pressure and tension forces were studied using Finite Element Method (FEM). The failure of the CT after becoming trapped in the oil well was attributed to the combined effect of a series of operations carried out to recover the CT string, which was trapped at a depth of 6,750 m. It is inferred that these operations, combined with the fatigue experienced by the CT due to physical deterioration from spooling and unspooling, contributed to mechanical damage, deformation, and finally the collapse of the CT.</div></div>","PeriodicalId":100824,"journal":{"name":"Journal of Pipeline Science and Engineering","volume":"6 1","pages":"Article 100303"},"PeriodicalIF":4.9,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145996437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, pipeline corrosion poses significant risks, leading to loss of containment, operational interruptions, and potential loss of life if undetected or unmitigated. The introduction of novel and corrosive fluid, such as hydrogen and carbon dioxide (CO<sub>2</sub>), is expected to exacerbate corrosion-related issues. Consequently, pipeline inspection techniques, particularly in-line inspection (ILI), are increasingly vital for corrosion monitoring. This paper establishes a framework for utilizing ILI data to develop machine learning models for corrosion prediction. Four tree-based machine learning techniques—eXtreme Gradient Boosting (XGBoost), Dropouts meet multiple Additive Regression Trees (DART), Light Gradient-Boosting Machine (LightGBM) with linear trees, and random forests—were employed to predict the maximum depth of corrosion defects based exclusively on historical ILI data. All models significantly outperformed the Naïve forecasting benchmark, with the best model achieving a root mean square error (RMSE) of 0.368 mm on the test set, surpassing the benchmark by 41.5 %. Furthermore, the accuracy of these models exceeded that of most service-based corrosion prediction models in the literature. This was achieved using an ILI dataset that exhibited extreme variations in maximum depth distribution and changes in reporting criteria. These findings indicate that the proposed framework is a superior alternative to service-based models, leveraging the vast amount of ILI data available to pipeline operators. Additionally, the service-agnostic framework supports the integration of process and service parameters, further enhancing the efficacy of machine learning models for corrosion prediction.</div></div>","PeriodicalId":100824,"journal":{"name":"Journal of Pipeline Science and Engineering","volume":"6 1","pages":"Article 100308"},"PeriodicalIF":4.9,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145996502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper collates pertinent research literature on NGD forecasting from 2011 to the present and examines and analyses the various scopes, cycles, and models of NGD prediction. This section first displays an overview of the scope of NGD forecasting projections in recent years, including global, national, regional, and local levels (e.g., by province, city, state, or enterprise), as well as household users. Secondly, it divides the forecasting cycle into short-term expectations (i.e., forecasts made on an hour-by-hour or daily basis) and medium-term forecasts (i.e., weekly or monthly forecasts). In addition, the paper analyses the mainstream forecasting direction in recent years, examines the methods of using and processing raw data, and explores the forecasting models, analyzing the difference between single and combined forecasting models. Finally, it considers how to select forecasting models. Furthermore, as NGD forecasting continues to present numerous challenges and deficiencies in both theoretical and practical terms, this article examines some of the key issues currently facing NGD forecasting. The article concludes with a summary of the current research status and an analysis of the future improvement and development direction of NGD forecasting.</div></div>","PeriodicalId":100824,"journal":{"name":"Journal of Pipeline Science and Engineering","volume":"6 1","pages":"Article 100319"},"PeriodicalIF":4.9,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145996504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In pipeline systems, a sudden change in cross-section leads to a sudden increase in the flow rate of cryogenic fluids and a sudden drop in local pressure. When the local pressure is lower than the saturation vapor pressure at that temperature, bubbles are generated and cavitation occurs. Cavitation damage caused by cavitation of cryogenic fluids is the main cause of leakage and even failure of pipeline transportation systems. Understanding the unsteady characteristics and mechanisms of cavitation in cryogenic fluids is crucial for accurately predicting and preventing cavitation, ensuring the safe and stable operation of pipeline systems. Compared with water, the ratio of liquid-vapor phase density and thermal conductivity of cryogenic fluids are smaller, and the saturated vapor pressure is more sensitive to temperature, so the cavitation mechanism is more complicated. This article reviews the research progress of numerical calculation, flow field characterization, cavitation damage properties and inhibition methods of cryogenic fluids cavitation, focusing on the inhibition of cryogenic cavitation by thermal effects and the classification and modification of cavitation models. In addition, this article discusses the morphological characteristics, unsteady state properties and the complexity of the cavitation flow field of cryogenic fluids cavitation. Finally, the outlook and challenges of the current research on cryogenic fluids cavitation are further summarized, and it is proposed that the exploration of cryogenic cavitation fluid-solid coupling, the microscopic simulation of cavitation bubbles, and the strengthening of the dynamic measurement capability of the flow field are the important directions for the further research on cryogenic cavitation of pipelines in the future.</div></div>","PeriodicalId":100824,"journal":{"name":"Journal of Pipeline Science and Engineering","volume":"5 4","pages":"Article 100269"},"PeriodicalIF":4.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145753881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The competition among gas molecules primarily occurs on the metal surface, where differences exist in the adsorption states of these gases. However, the mechanisms underlying their effects on hydrogen dissociative adsorption remain unclear. In this study, density functional theory (DFT) and first-principles molecular dynamics (FPMD) calculations were employed to model the adsorption of H<sub>2</sub>, O<sub>2</sub>, and H<sub>2</sub>O on Fe(100) surface. The aim was to elucidate the mechanisms by which O<sub>2</sub> and H<sub>2</sub>O affect hydrogen dissociative adsorption and to clarify the dynamics of the hydrogen dissociation process. The results reveal that O<sub>2</sub> exhibits high adsorption and dissociation activity. The adsorbed O atoms increase the energy barrier for hydrogen dissociative adsorption and weaken the interaction between hydrogen and iron atoms. In contrast to strong inhibitory effect of O<sub>2</sub>, H<sub>2</sub>O presents a more complex behavior. On one hand, H<sub>2</sub>O can physically adsorb onto the pipeline surface, and reduces the stability of subsequently adsorbed H atoms without inhibiting hydrogen dissociation. On the other hand, charge exchange between H<sub>2</sub>O molecule and substrate atoms causes the Fe surface to acquire a negative charge. This charge redistribution decreases the surface potential, making the steel more prone to corrosive cathodic hydrogen precipitation reactions, thereby promoting hydrogen entry.
