Thermal Insulation Handbook for the Oil, Gas, and Petrochemical Industries

In permafrost regions, long distance buried pipelines are widely used to transport oil and natural gas resources. However, pipeline problems occur frequently due to the complicated surrounding environment and transportation requirement of positive temperature. In this study, a thermal insulation layer was applied to mitigate permafrost degeneration around the buried oil-gas pipelines. Based on engineering background of the Sebei-Xining-Lanzhou natural gas pipeline in China, an indoor model test was designed and carried out in which many key indices, such as the temperature regime, vertical displacement, pipeline wall stress, and water content, were closely monitored. The test results indicate that the large heat loss of the buried pipeline produces a rapid increase in ground temperatures which seriously reduces the bearing capacity of the permafrost foundation. The buried oil-gas pipelines with a thermal insulation layer can effectively reduce the thawing range and vertical displacement of the permafrost foundation around the buried pipelines, so as to control the stress of the pipeline wall in the normal range and protect the safe and stable operation of the buried oil-gas pipelines. The experimental results can serve as a reference for the construction, operation, and maintenance of buried oil-gas pipelines in permafrost regions.

Introduction: To prevent accidents and minimize the risk of unexpected disasters in the oil, gas, and petrochemical industries, an inspection of equipment in terms of mechanical integrity and safe and consistent service providing are of utmost importance. The purpose of this study is integrated risk and asset management by implementing risk-based inspection techniques in the oil, gas, and petrochemical industries. Methods: Firstly, this systematic review study identified a list of keywords based on RBI and then exclusively on the internal and external databases of Science Direct, Pub med, Google Squalor, SDI, Google Searcher, and Scopus without a time limit. Afterward, keywords, including risk management, probability of failure, asset integrated management, risk-based inspection, consequences of failure, and corrosion management, were searched. Result: A review of various studies showed that the risk-based inspection approach provided the necessary platform for upgrading and formulating new inspection, repair, maintenance, equipment risk management systems and asset integration in the oil, gas, and petrochemical industries and played a significant role in reducing the risk levels to its acceptable limits. Conclusion: By analyzing the results of studies, it was found that using this method will lead to the effective implementation of risk management, reliability, and corrosion management in oil, gas, and petrochemical industries. In fact, the system intended to provide process safety, increase risk perception of damage in line with the respective risk management, and ensure the integrity of the assets in operational units.

Robots have emerged as a force in infrastructure inspection. That is especially true in the oil, gas, and petrochemical industries, which are not an obvious test bed for new technology. Because their assets range into the billions of dollars, their managers are very cautious about entrusting their facilities to any new technology. Yet even something as simple as inspecting storage tanks for corrosion and leaks shows why robots are increasingly popular. This article delves into the current status and future outlook for robotic inspection efficiency.
