This book was released on 2020 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pipeline integrity management refers to an approach of understanding and operating pipelines in a safe and reliable manner. In this work, firstly, a probabilistic predictive model for internal corrosion of natural gas pipelines subject to aqueous CO2/H2S environment has been proposed. The model regards uniform and pitting corrosion as two main corrosion mechanisms and has been calibrated with the experimental data in a deterministic framework. Methodologies of simulating and accounting for temporal and spatial variabilities of operating parameters have been proposed and applied to the model for field applications. The model has been validated against field data from eight wet gas gathering pipelines in a probabilistic framework. Secondly, a reinforcement learning (RL)-based maintenance scheduler has been proposed for pipeline maintenance optimization problems by leveraging the proposed predictive corrosion model and the Q-learning and Sarsa algorithms. A case study has shown the superiority of the proposed maintenance scheduler over the periodic maintenance policy in reducing the maintenance costs. Finally, the previous two parts of work have been integrated into a pipeline system integrity management software featuring pipeline health monitoring, corrosion prognosis, system-level failure analysis, sensor placement optimization, and inspection/maintenance optimization. A case study has been provided to demonstrate the capabilities of the software.

Book Synopsis Recommended Practice for Corrosion Management of Pipelines in Oil & Gas Production and Transportation by : Bijan Kermani
Download or read book Recommended Practice for Corrosion Management of Pipelines in Oil & Gas Production and Transportation written by Bijan Kermani and published by CRC Press. This book was released on 2017-12-02 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: First Published in 2017. Pipeline integrity is key to maintaining operational success, safety and security and minimising harm to the environment. Corrosion is a dominant contributory factor to failures, leaks and integrity threats in pipelines. Therefore, its optimum control within an integrity management framework is paramount for the cost-effective design of facilities and ensuring continued, uninterrupted and safe operations within the expected design life. This recommended practice (RP) is a compendium of current best practices and state-of-the-art knowledge by major operators, engineering contractors and service companies involved in hydrocarbon pro-duction and transportation. The RP incorporates some minimum operational requirements and practices to ensure that when man-aging corrosion in pipelines, fundamental principles are followed. It covers management of corrosion for pipelines carrying hydrocarbons, injection water and/or produced water from design to decommissioning. It is structured to follow the logical steps of a basic corrosion management process and makes references to relevant and available international standards and/or recommended practices. It is intended for use by personnel from the petroleum industry having knowledge of corrosion and materials. It is hoped that this RP will prove to be a key reference document for engineers, suppliers and con-tractors working in the oil and gas industry, paving the way for corrosion-free operation of pipelines with the ultimate goal of improving safety, security and minimising the impact on the environment
Book Synopsis Reliability-based Management of Buried Pipelines Considering External Corrosion Defects by : Seyedeh Azadeh Miran
Download or read book Reliability-based Management of Buried Pipelines Considering External Corrosion Defects written by Seyedeh Azadeh Miran and published by . This book was released on 2016 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corrosion is one of the main deteriorating mechanisms that degrade the energy pipeline integrity, due to transferring corrosive fluid or gas and interacting with corrosive environment. Corrosion defects are usually detected by periodical inspections using in-line inspection (ILI) methods. In order to ensure pipeline safety, this study develops a cost-effective maintenance strategy that consists of three aspects: corrosion growth model development using ILI data, time-dependent performance evaluation, and optimal inspection interval determination. In particular, the proposed study is applied to a cathodic protected buried steel pipeline located in Mexico. First, time-dependent power-law formulation is adopted to probabilistically characterize growth of the maximum depth and length of the external corrosion defects. Dependency between defect depth and length are considered in the model development and generation of the corrosion defects over time is characterized by the homogenous Poisson process. The growth models unknown parameters are evaluated based on the ILI data through the Bayesian updating method with Markov Chain Monte Carlo (MCMC) simulation technique. The proposed corrosion growth models can be used when either matched or non-matched defects are available, and have ability to consider newly generated defects since last inspection. Results of this part of study show that both depth and length growth models can predict damage quantities reasonably well and a strong correlation between defect depth and length is found. Next, time-dependent system failure probabilities are evaluated using developed corrosion growth models considering prevailing uncertainties where three failure modes, namely small leak, large leak and rupture are considered. Performance of the pipeline is evaluated through failure probability per km (or called a sub-system) where each sub-system is considered as a series system of detected and newly generated defects within that sub-system. Sensitivity analysis is also performed to determine to which incorporated parameter(s) in the growth models reliability of the studied pipeline is most sensitive. The reliability analysis results suggest that newly generated defects should be considered in calculating failure probability, especially for prediction of long-term performance of the pipeline and also, impact of the statistical uncertainty in the model parameters is significant that should be considered in the reliability analysis. Finally, with the evaluated time-dependent failure probabilities, a life cycle-cost analysis is conducted to determine optimal inspection interval of studied pipeline. The expected total life-cycle costs consists construction cost and expected costs of inspections, repair, and failure. The repair is conducted when failure probability from any described failure mode exceeds pre-defined probability threshold after each inspection. Moreover, this study also investigates impact of repair threshold values and unit costs of inspection and failure on the expected total life-cycle cost and optimal inspection interval through a parametric study. The analysis suggests that a smaller inspection interval leads to higher inspection costs, but can lower failure cost and also repair cost is less significant compared to inspection and failure costs.

Download or read book Natural Gas Pipeline Safety written by Government Accountability Office and published by Createspace Independent Publishing Platform. This book was released on 2017-09-13 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Pipeline Safety Improvement Act of 2002 established a risk-based program for gas transmission pipelines-the integrity management program. The program requires operators of natural and other gas transmission pipelines to identify "high consequence areas" where pipeline incidents would most severely affect public safety, such as those occurring in highly populated or frequented areas. Operators must assess pipelines in these areas for safety risks and repair or replace any defective segments. Operators must also submit data on performance measures to the Pipeline and Hazardous Materials Safety Administration (PHMSA). The 2002 act also directed GAO to assess this program's effects on public safety. Accordingly, we examined (1) the effect on public safety of the integrity management program and (2) PHMSA and state pipeline agencies' plans to oversee operators' implementation of program requirements. To fulfill these objectives, GAO interviewed 51 gas pipeline operators and surveyed all state pipeline agencies.
Book Synopsis Development of Probabilistic Corrosion Growth Models with Applications in Integrity Management of Pipelines by : Shenwei Zhang

This book was released on 2014 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal-loss corrosion is a major threat to the structural integrity and safe operation of underground oil and gas pipelines worldwide. The reliability-based corrosion management program has been increasingly used in the pipeline industry, which typically includes three tasks, namely periodic high-resolution inline inspections (ILIs) to detect and size corrosion defects on a given pipeline, engineering critical assessment of the corrosion defects reported by the inspection tool and mitigation of defects. This study addresses the core involved in the reliability-based corrosion management program. First, the stochastic process in conjunction with the hierarchical Bayesian methodology is used to characterize the growth of defect depth using imperfect ILI data. The biases, random scattering errors as well as the correlations between the random scattering errors associated with the ILI tools are accounted for in the Bayesian inference. The Markov Chain Monte Carlo (MCMC) simulation techniques are employed to carry out the Bayesian updating and numerically evaluate the posterior distributions of the parameters in the growth model. Second, a simulation-based methodology is presented to evaluate the time-dependent system reliability of pressurized energy pipelines containing multiple active metal-loss corrosion defects using the developed growth models. Lastly, a probabilistic investigation is carried out to determine the optimal inspection interval for the newly-built onshore underground natural gas pipelines with respect to external metal-loss corrosion by considering the generation of corrosion defects over time and time-dependent growth of individual defects. The proposed methodology will facilitate the reliability-based corrosion management for corroding pipelines.
