Risk assessment in a hypothetical network pipeline in UK transporting carbon dioxide

Localization of CO2 gas leakages through acoustic emission multi-sensor fusion based on wavelet-RBFN modeling

“…Here the time difference is chosen as one of the feature vectors. Because the [3,0] node of wavelet packet decomposition contains the characteristic frequency of the leakage signal, the cross-correlation analysis of the signal S30 of each channel of wavelet packet decomposition is taken to obtain the cross-correlation time difference of any two channels as a feature vector. The cross-correlation results for any two channels are shown in Fig.6.…”

“…Xiaojuan Han 1 , Song Zhao 1 , Xiwang Cui 1,3,4 and Yong Yan 1,2 method. The fiber optic method [10] does offer high-precision leak localization; however, it requires digging up the soil above the pipe for its installation and maintenance.…”

“…CO 2 transportation by large-scale, long-distance pipelines may pass through factories, ports and cities. Any leakage accident will seriously endanger the ecological environment and human health [3]. Therefore, leak detection and localization of pipelines is indispensable for CO 2 transportation [4].…”

Aprioristic Integration of Process Operations and Risk Analysis: Definition of the Weighted F&EI-Based Concept and Application to AG2S Technology

“…In this framework, the industry has put significant resources into managing hazards and risks associated with large plants, hazardous materials, and processes . A structured approach to process risk management requires hazard identification and classification, risk analysis, and measures for reduction and control to the lowest practical level while optimizing other business targets. , Hazard identification and scenario definition are still the weakest and most uncertain parts of risk assessment . The well-known methods result in the incompleteness of identifying possible hazards and unfolding scenarios, among those also are contexts leading to severe damage, albeit with a relatively low occurrence frequency .…”

Pressurized CO 2 releases in the framework of carbon sequestration and enhanced oil recovery safety analysis: Experiments and model

“…In this framework, Carbon Capture and Storage (CCS) and the Enhanced Oil Recovery (EOR) activities emerged as promising solutions in governing CO 2 emissions, and forecasts expect several pressurized pipelines transporting large quantities of CO 2 over long distances to be built within the next decades (Mazzoldi et al, 2012;Vianello et al, 2016). However, although pipeline transmission is a mature and safe technology, the lack of operational experience in CO 2 handling infrastructures poses difficulties in the hazard identi-fication and QRA (Quantitative Risk Assessment) procedures (Barrie et al, 2005;Ahmad et al, 2013).…”
